Cumulus.ini (preserving history)

Introduction

• Cumulus.ini is a text file containing initialization parameters used by the Cumulus 1.x.x, or Cumulus MX, application.
• It is only read when Cumulus (of either flavour) starts up. When Cumulus (either flavour) is run for very first time, the file does not exist, as it is not included in the download (of either flavour). For MX only, if the file does exist as MX starts, a backup is taken so if you subsequently change any settings you can go back to how it was before you made those changes.
• Cumulus (1 or 2 or MX) creates a new version of this file when it shuts down, if this is the first run of the software this will create the file for first time.
• The file shows as 'modified date' the last time that Cumulus was shut down, the file will contain the contents of the application's configuration screens and also any parameters that were in any previous copy of the file that cannot be configured within Cumulus.
• Note this Cumulus save action may change the order, or add lines, compared to any file that you manually edited.
• For Cumulus MX only, a back up copy of Cumulus.ini is stored at end of each day (together with some of the log files).
• If you do need to edit the file, close Cumulus first to ensure you are working on latest contents, and your edit cannot conflict with any edit Cumulus may be making. When Cumulus restarts it will read the file again and see any edits you have made.

The parameters listed can change the look of Cumulus, can hold basic information about your location, can amend the way Cumulus interfaces with your weather station, can hold the settings used to interface with your website, and with various external websites.

Later on this page there is a table showing parameters that may be in the configuration file, the default value for each attribute is mentioned, and it is made clear whether that parameter can be set through the settings screen in the software or must be manually added to the file. The list was created for Cumulus 1.x.y, and all of it applies to the final formal release. The majority of the parameters are also used by Cumulus MX, which can edit in its settings screens some that Cumulus 1 cannot edit. There are also extra parameters that only apply to MX, plus some extra values available for some attributes like weather station make.

If you are using an older Cumulus 1 version, then checking the release information may be advisable to identify the sections applicable to your build, and to identify if the parameters allowed within those sections may be a subset of those listed below as available in latest release of Cumulus 1.

Similarly, the parameters available may vary between different versions/builds of MX, again checking the release information may be advisable to identify the sections applicable to your build, and to identify if the parameters allowed within those sections may be a subset of those listed below.

Creating Configuration File

When you download Cumulus 1 or MX, there is no configuration file included in the download. So when you first use the software, either flavour of Cumulus, you will need to enter some settings, and that will lead to creation of the main configuration file. How to enter these minimum settings will be described next.

Cumulus 1

1. If you start Cumulus 1, without a configuration file, then it will open at the station settings screen. Follow the link to see what the screen looks like for old builds and newer builds.
2. At the very minimum, you must select a station type in the top left frame, and units in the middle of the screen.
3. Most other entries on the screen have defaults, but you might want to change some of these. Click the Help button at bottom right of the screen for guidance on what each choice means.
4. Optionally, move to other settings screens, accessed from the main screen using the Configuration menu. Again click Help on each screen for more information.
5. Optionally create a Strings.ini file (look up the cross reference if you want to do this now, but you can leave it to later) where you can tailor a number of texts that Cumulus produces.
6. Back on the main screen, in the File menu click Exit. This is the action that creates the configuration file, the first part of the name is taken from the name of the executable, but the extension is .ini (instead of .exe).
7. Restart Cumulus 1, it will read the configuration file, and connect to your weather station. Note that on this run, it does not read any archive data, it just reads what the weather station holds from now on. See this FAQ for a way to change this behavoir.

Cumulus MX

1. If you start Cumulus MX without a configuration file, and you have a screen attached so you can see the output from the engine, it will show this:
2. As you can see, it is running, but it does not know what station type, so it cannot connect to it, and will not do anything more.
3. At this stage, MX creates a very basic Cumulus.ini with the default settings (shown below).
4. Open the user interface, and select the station settings if necessary:
   
5. At the very minimum, you must select a station type and units (as shown in image here)
6. Optionally, move down the page, entering more settings, or move to other settings pages accessed from the menu seen in the image
7. Optionally create a Strings.ini file (look up the cross reference if you want to do this now, but you can leave it to later) where you can tailor a number of texts that Cumulus produces.
8. If you have a screen attached to the device running the MX engine, you can click in that screen and terminate Cumulus MX. Otherwise do whatever is needed to end the MX executable on your installation. This is the action that will create the main configuration file.
9. Restart Cumulus MX, it will read the configuration file, find the weather station, and start reading the weather data from it. On this first access to your weather station, it will not read any archive data, just the live data while MX remains running.

Swapping from Cumulus 1 to MX

If you swap from Cumulus 1 to MX, your Cumulus 1 configuration files can be read by MX provided the initial letter of the file name is a capital 'C' and the other letters are in lower case. Once it has been processed by MX, the ex Cumulus 1 main configuration file will gain a lot of new entries, and a number will be ignored.

Configuration File names

Cumulus MX

Don't rename the CumulusMX.exe file name as it must use that mixture of upper and lower case. The main configuration file is always called Cumulus.ini (it must start with a capital 'C') and is located in the directory in which you installed CumulusMX.exe. All the characters used within the configuration file must be within ASCII range. No other "Cumulus.ini" files are required. Most of the sections are same in both flavours of Cumulus, but MX does not use [MainForm].

Cumulus 1

As downloaded, the Cumulus 1 executable is called cumulus.exe and all in lowercase. The configuration file that it creates on first use will take the name of the executable file (keeping to the same case) and add the extension .ini (instead of .exe) and will be stored in same folder as the executable, it will contain all sections.

If you renamed that executable file to say Cumulus1.exe it will still work in the same way so the main configuration file then takes that name (i.e. Cumulus1.ini) in the same folder but this file will be lacking one section, and another configuration file will be created called Cumulus.ini in that folder, this second one will have the one missing section.

An additional configuration file, also called Cumulus.ini, can be created by Cumulus 1 to store the position of the NOAA parameter editing screen, this will be created the first time you edit NOAA parameters and will be stored in the "Reports" folder this only contains a single section and relates to the screen used for NOAA reports.

Upgrading to New Build

Installing a new build of Cumulus (whatever version) over the existing installation does not affect this settings file. No build of Cumulus contains a 'Cumulus.ini' file. If Cumulus software detects a 'Cumulus.ini' when it starts, it looks in that for settings; if it does not find the file, then Cumulus will expect you to tell it some settings, others have defaults. See Cumulus Help, release announcement, and other provided documentation for more.

Moving from Cumulus 1 to MX

There are differences between parameters available in these flavours of Cumulus.

Parameters changed

Replace: IncludeSTDImages=1 by IncludeGraphDataFiles=1 in [FTP site]

Replace: Port=n where n is a number, by ComportName=COM1 where the value is a string and might be different to the default shown

Parameters added

This depends upon which version of MX you are running, please see all release announcements for details.

File Structure

The main file consists of a number of sections, each with a heading delimited by '[ ]', (although the order in the file may be different to that in this article). Parameter lines are in the form 'attribute=value' and grouped by those sections. Those attributes can be listed in any order, Cumulus software will always add new attributes to the end of the section. If you are manually adding attributes, it may be best if you sort the attributes so they appear in alphabetical order and thus ensure you do not duplicate attribute names with different values.

Some sections relate to the external websites that Cumulus can optionally supply with updates. These are set by configuration screens and the whole sections will always be present. If you do not use those external services their parameters will be set to the defaults.

Each new version of cumulus may add additional parameters set by revised configuration screens (these initially appear at the end of the relevant section), and/or permit additional parameters to be added manually (these can be inserted anywhere within the section).

Completeness of this list

Please note that this list is not updated by the developers when they change the software to react to a new attribute, therefore there is no guarantee that all attributes available appear in this documentation.

If you spot a parameter that is missing from this list (check you are looking in the right section, and under the correct sub-heading where a section is sub-divided for ease of using this article), then please add it to this Wiki article. None of the authors who have contributed so far can claim completeness. Sometimes a search on the forum for something else reveals a mention of an additional parameter that can be added to the file but has not been previously added to this list.

There have been over a thousand builds of Cumulus version 1 and much of this article has been written based on experience in using Cumulus, it may not reflect every parameter that can be manually added to the file, although it does reflect all those linked with settings made on various screens.

Beta builds

There are no beta builds of either Cumulus 1 or Cumulus MX. Although much of the content is identical (and shown below), there are differences between this configuration file for Cumulus 1 as shown here and for MX, the differences for MX are given in this article.

When there is a beta build, there may be changes to the information shown below with additional sections and/or additional parameters (attribute=value) under test. Brief details of such changes will be given in the support forum announcement for the relevant build. New sections and/or attributes and/or values for beta versions of Cumulus are not listed here until the version becomes 'live', but for details of beta tests see the forum.

CURRENTLY CUMULUS MX specific parameters are listed on another page.

Editing the file

Initialisation

When Cumulus 1.x.y is run for the very first time, the Station settings screen within the Configuration menu is displayed, so that the basic minimum settings can be entered into a 'Cumulus.ini' that it will then create. Should you accidentally delete Cumulus.ini this would happen again, so it is always best to take a backup of the complete Cumulus directory and sub-directories so nothing is lost in such a situation.

For Cumulus MX, again when it is run for first time, unless it has been given a Cumulus.ini file created for Cumulus 1, you will need to set some settings. However, Cumulus MX does save a back up automatically at the end of each day.

See Setup for further advice, noting in particular that some settings (such as units, date/time formats) should stay unchanged, because if you do change those you will need to edit all the other files that Cumulus creates to reflect those changes.

Settings controlled by application

Many configuration parameter lines are changed from the various application edit, view, or configuration screens, and so making any amendments using those screens should ensure your replacement values are acceptable. You should never edit these parameter lines directly in the file while Cumulus is running, as when Cumulus shuts down it will replace your amendments to these parameters with the contents of the relevant application Edit/View/Configuration screens.

You can edit them in the file with Cumulus stopped, but beware of selecting invalid values for these parameters, generally it is safer to use the application to edit them (unless you are importing values from another setup), and Cumulus will read the new values when it is next restarted.

Settings independent of application

Some configuration settings can only be applied by editing this file to insert a new parameter line; they do not appear anywhere in the configuration screens. When Cumulus is creating a configuration file it does not write any parameters that are not in its settings screens, so they do not appear with default values - in other words, you need to add them if you want to set them. Make sure you place these additional parameters in the correct section as listed below.

Editing outside Cumulus

• If you are using Cumulus 1, it is best to take a copy of the existing cumulus.ini file before you make any changes (either by using application screens or by editing the file), so you can return to the original if necessary. MX automatically takes back ups, so you can return to an earlier version if necessary
• If your system is configured to use a comma for a decimal separator, then you should use a comma in any decimal values that you set in this file.
• You should use a simple text editor (not a rich text editor nor word processor) to edit this file as only letters, numerical digits, decimal separators and the equals symbol are allowed in any parameter. If you use a spreadsheet program to make use of the manipulation it offers, ensure it is set to output in pure text.
• The parameter lines (attribute=value) can be in any order, but must be in the correct section. You might find it helpful to sort the attributes within a section into alphabetical order, to ensure you have no duplicates and to make it easier to find the particular parameter line you may wish to edit in the future.

File Contents

The section called "[FTP site]" should obey that use of capitals and lower-case. Other sections should be named as shown.

Minimum Content of "Cumulus.ini"

The minimum content of the main configuration file is an entry for every setting that can be defined in the software (whichever flavour you are using, there are more options in MX).

Default and Example Values

The entries shown in the 'parameter line entry' column include the default value from the configuration screen where applicable, a typical example value where appropriate, or just the attribute and an equals sign where there is no default nor typical value.

Section by Section

Section: MainForm

This section applies to Cumulus 1 only.

There are two actions that will create this section in a file that is always called Cumulus.ini stored in different locations according to the creating action:

• If you edit NOAA parameters then One file with this section is stored in the reports sub-directory and it stores the position of your last saved NOAA screen.
• If you have set 'Save main window position' on Display settings screen, this section appears in the Cumulus.ini file found in same directory as cumulus.exe, and it stores the position of the main Cumulus screen on your monitor.

Parameter Line Entry	Function
[MainForm]	Section name - the following parameters relate to the Cumulus or NOAA screen position.
Left=100	The last saved Cumulus main or NOAA screen position, in pixels from the left-hand edge of the screen.
Top=50	The last saved Cumulus main or NOAA screen position, in pixels from the top edge of the screen

Section: Station

See individual parameters for specific instructions on setting them.

In many cases this is by using Station Configuration Screen in Cumulus 1, but if the parameter line does not exist in your file, then insert it using a file editor as per instructions above.

There is a station settings page in MX. Again, it does not cover every setting, and for some you need to stop MX and edit this file directly.

Parameter Line Entry	Function
[Station]	Section name - the following parameters relate to all weather stations.
Both Cumulus flavours - in MX edit in Station Settings, for Cumulus 1 edit in Station Configuration Screen
Type= -1	Station Type as set by the checked radio box in the Station Configuration Screen, Station Type block. For details of Supported_Devices click that link. -1= default value, before a selection from those below is made. In Cumulus 1, this causes the configuration screen to be shown so that you start set up. In MX a message appears in the terminal (Windows command) screen saying that station type not known (see #Cumulus_MX section above. 0=Vantage Pro station 1=Vantage Pro2 station 2=WMR-928 station 3=WM-918 station For Oregon Scientific stations and similar re-badged stations (Huger, Radio Shack etc) which have a serial port connection, if your model is not listed, try WM-918 if your station has wired connections, and WMR-928 if it is wireless. 4=Reading from file EasyWeather.dat (using EasyWeather software version 6.2, or earlier, running continuously with Cumulus). Fine Offset weather stations that record Solar and UV measurements output to EasyWeatherPlus.dat file when Easyweather software version 6.x is running. This has the same fields as easyweather.dat, plus two extra fields for Solar and UV data at the end, and so Cumulus can understand the fields you must also have LogExtraSensors=1 set. NOTE: You can also use Type=4 if you want to run Cumulus with reduced functionality without a weather station attached, to view historical observations. A full set of (historic) files in the data subfolder copied from a system with a weather station attached is needed, but in this case, the EWFile= attribute should be at its default of not having any filename value. 5=Fine Offset, Maplin, Chas Olsen, MyDEL, Nevada, Watson, Tycon Power, Aercus, etc as defined in Fine Offset section in Supported_Devices article (without solar measurement sensors (with or without solar recharging)) 6=WS2300 (For all La Crosse WS23xx models) 7=Fine Offset/Watson/MyDel etc with Solar Sensors as defined in Fine Offset with UV/Light sensor in Supported_Devices article. 8=WMR100 9=WMR200 10=Instromet (with optional extra solar sensors or without) Additional values available in MX only: 11=Davis WLL 12=Ecowitt GW1000 and Froggit DP1500 (and any equivalents)
Model="your Model description"	The weather station model description that you want output by the web tag <#stationtype> - you choose what text appears for this on (from version 1.9.x) 'Display' settings screen within Configuration menu - the field is at the bottom left of that screen). - this does not appear in the station settings, stop MX, and add it directly into Cumulus.ini within this [Station] section.
RecordSetTimeoutHrs=24	Available in MX version 3.5.1 onwards only, allows the time from when a record is set to when it is cleared to be varied. The web tags: TempRecordSet, WindRecordSet, RainRecordSet, HumidityRecordSet, PressureRecordSet, HighTempRecordSet,LowTempRecordSet, HighAppTempRecordSet, LowAppTempRecordSet, HighHeatIndexRecordSet, LowWindChillRecordSet, HighMinTempRecordSet, LowMaxTempRecordSet, HighDewPointRecordSet, LowDewPointRecordSet, HighWindGustRecordSet, HighWindSpeedRecordSet, HighRainRateRecordSet,HighHourlyRainRecordSet, HighDailyRainRecordSet, HighMonthlyRainRecordSet, HighhHumidityRecordSet, HighWindrunRecordSet, LowHumidityRecordSet, HighPressureRecordSet, LowPressureRecordSet, LongestDryPeriodRecordSet, LongestWetPeriodRecordSet, HighTempRangeRecordSet, LowTempRangeRecordSet will all return 1 from when relevant record is set for the period of time set here (default 24 hours) and then reset to 0.
Latitude=0	You are advised not to directly edit this parameter in the file, but to enter the settings via the screen provide in software where you type Latitude (unsigned) Degrees, Minutes, Seconds and select 'N' or 'S'. Do this in the Station Configuration Screen Location block. Exactly same entries, enter using station settings by expanding location section. Value in this parameter is Latitude in Decimal Degrees based on what you have entered, Positive for North, Negative for South
Longitude=0	You are advised not to directly edit this parameter in the file, but to type Longitude (unsigned) Degrees, Minutes, Seconds and select 'E' or 'W'. The place to do this is as described for Latitude depending on Cumulus flavour. Value in this parameter is Longitude in Decimal Degrees based on what you have entered, Positive for East, Negative for West
LatTxt=	You are advised not to directly edit this parameter in the file, it contains Latitude in text string format of hemisphere D, M and S. HTML ampersand codes are used for spaces and unit characters.
LonTxt=	You are advised not to directly edit this parameter in the file, it contains Longitude in text string format of hemisphere degrees, minutes and seconds. HTML ampersand codes are used for spaces and DMS characters.
Altitude=0	your station altitude (default is zero) as entered in same place as other parameters. See Cumulus Help for that screen. See next parameter to choose unit.
AltitudeInFeet=1	Altitude measurement unit for value in previous parameter. 0 = metres Above Sea Level 1 = feet ASL
SpecialLog=1	This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. If the parameter is not included in the file or the parameter is 'SpecialLog=0', the special log file is not updated. If you do include this parameter then the inside and outside temperature, humidity and dew point are logged at the same interval as values are logged to Standard log files. Not implemented in MX.
PeakGustMinutes=N	This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. This line can be added in the [Station] section of the Cumulus.ini. With this parameter, N is the number of minutes over which Cumulus calculates its highest wind gust. Without this parameter, the default of 10 minutes, the international standard duration, is used. If you select 60, then Cumulus would calculate rolling 60-minute highest wind gust speeds. To be in line with met stations in Cz, select 30.
AvgSpeedMinutes=N	This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. This line can be added in the [Station] section of the Cumulus.ini, if you have set the next parameter so that Cumulus does its own calculation of average wind speed. With this parameter, N is the number of minutes over which Cumulus calculates its average speed, if you have Cumulus set to do this with the next parameter enabled. Without it, the default of 10 minutes, the international standard duration, is used if Cumulus is set to calculate average wind speeds. If you selected 60, then Cumulus would calculate rolling 60-minute average wind speeds. To be in line with ASOS stations in USA, select 2.
Wind10MinAverage=0	Selected on same screen as other parameters. 0 = Disabled (default), Cumulus will display the value supplied by the station. This is a 10 minute average for Davis stations, but an average over a shorter period for Oregon Scientific and Fine Offset stations, see FAQ#Cumulus_is_showing_a_different_wind_speed_compared_to_my_console. 1 = Enabled, Cumulus will calculate and display a N-minute average wind speed where N is defined by the previous parameter if present, otherwise defaults to 10, the international standard duration used to calculate average wind speeds.
UseSpeedForAvgCalc=0	Selected on same screen as other parameters. 0 = Disabled (default), Cumulus will display the average wind speed value supplied by the station, see FAQ#Cumulus_is_showing_a_different_wind_speed_compared_to_my_console. 1 = Enabled, Cumulus will use the longer-term 'speed' values in the average speed calculation. The preceding 'Wind10MinAverage' option must be enabled for this parameter to have any effect. Note that there isn't really any point enabling this option for Davis stations, as their 'longer-term speed' is a 10 minute average anyway; neither for La Crosse stations, as they only supply one wind speed anyway.
RoundWindSpeed=0	Selected on same screen as other parameters. 0 = Disabled (default), Cumulus will display the wind speed value to the precision used by the station. 1 = Enabled, this setting causes wind speeds to be rounded to the nearest integer.
AvgBearingMinutes=N	This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. This line can be added in the [Station] section of the Cumulus.ini, with this parameter N is the number of minutes over which Cumulus calculates (by treating the wind as a vector and taking into account the speed as well as direction) its average bearing. Without it, the default sampling time = 10 minutes. Note the max number of wind samples stored by Cumulus is 720, so the maximum effective value for N for Fine Offset stations that are read every 10 seconds is 120 (2 hours) while for Davis stations that are sampled every 2 to 3 seconds the maximum effective value is only about 30 (minutes). See next parameter for behaviour when calm.
CalculatedDP=0	Selected on same screen as other parameters. 0 = Disabled, Cumulus will display the dew point value supplied by the station. 1 = Enabled, Cumulus will calculate the dew point instead. This avoids the restriction in the Oregon Scientific stations where the dew point can never be below freezing point.
CalculatedWC=0	Selected on same screen as other parameters. Available only from version 1.8.3 0 = Disabled 1 = Enabled, Cumulus will calculate the wind chill instead of using the value supplied by the station. You should set this if you have specified any calibration values for wind and/or temperature, so that Cumulus can also apply those adjustments to the wind chill. Note that some stations (Fine Offset, for example), do not make a wind chill value available to Cumulus. For these, Cumulus always calculates it.
UseWindChillCutOff=1	This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. If the parameter is not included in the file, the default value is assumed. Purpose is to disable 'calculate Wind chill only if temperature less than 10°C rule'. 0 = Disabled, Cumulus will use any wind speed of 3 mph or more, to modify the temperature, and determine the wind chill ignoring the temperature criterion 1 = Enabled (default), Cumulus will use both 10°C temperature and 3 mph wind speed criterions to determine if wind chill applies. Note if your station is a type that supplies wind chill to Cumulus; that CalculatedWC=1 is needed for this setting to have any effect [i.e. you need to set Cumulus (see parameter directly above) to calculate the wind chill as this setting cannot change how your weather station calculates wind chill].
ChillHourThreshold=45	This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. The temperature threshold is specified in the units that you use in Cumulus (see Heat/cold_degree_days_and_Chill_hours). The default is exactly 45 degrees Fahrenheit (or exactly 7 degrees Celsius, note that is not exactly 45oF depending on which units you use) if the parameter has not been included.
ChillHourSeasonStart=10	This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. The season start figure is the calendar month number (1=January to 12= December). The default if this parameter is not specified is October (month 10).
RolloverHour=0	Log roll over time as selected on the same screen as other parameters 0 = midnight 9 = 9am/10am
Use10amInSummer=1	Daylight saving correction for 9am roll over, Selected on same screen as other parameters. 0 = Use 9am in summer (use 10am not checked on Station Configuration Screen) 1 = Use 10am in summer selected on Station Configuration Screen
SnowDepthHour=9	This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. If the parameter is not included in the file, the default value is assumed. This line needs to be added in the [Station] section of the Cumulus.ini, it is the Snow lying/falling roll over time (time when yesterday's values in log.xml are forgotten) - Allowed values are 0 to 23 and represent the time to the nearest hour that snow depth measurements are taken. 0 = midnight (default) 9 = 9am, 13 = 1pm etc. Note this time is independent of your rollover time selections in the two preceding parameters.
WarnMultiple=0	Set as 'Stop 2nd instance' in the Station Configuration Screen Program Settings block. Controls behaviour for Multiple Instances of Cumulus running on PC. Requires a Cumulus restart if value toggled, before new behaviour will take effect. 0 = Disabled, (default) Multiple instances allowed. 1 = Enabled, prevents multiple instances of Cumulus from running. Not available in earliest builds of any Cumulus flavour.
ConfirmClose=0	Selected in the Station Configuration Screen Program Settings block. Toggles Confirmation you wish to close Cumulus application after telling it to close 0 = Disabled, application will close immediately 1 = Enabled, application will prompt for confirmation that you wish to close it (do not use this if you might suspend/standby/hibernate your computer) Ignored by MX.
CloseOnSuspend=1	If this is selected, in the Station Configuration Screen Program Settings block, Cumulus will close if you suspend/standby/hibernate your computer. You should not select the previous parameter 'ConfirmClose' if you use this option. 0 = Disabled, application will not close if you suspend/standby/hibernate your computer (it is highly recommended you close Cumulus manually before your computer is put into suspend/standby/hibernate state) 1 = Enabled, application will close on suspend/standby/hibernate of your computer (recommended if your computer can go into any of these states when left alone) Ignored by MX
DataLogInterval=2	Selected in the Station Configuration Screen Data log interval block on the right hand side and defines frequency for Cumulus to log weather readings and derived figures in the Standard_log_files and, when applicable, in Extra_Sensor_Files. 0 = 1 min 1 = 5 mins 2 = 10 mins (default) 3 = 15 mins 4 = 20 mins 5 = 30 mins Notes: Some weather station types do not have an in-built logger, so Cumulus cannot read any archive data from them, and they don't have a station console logging interval, to determine what this Cumulus logging interval should be. For a Davis station MUST set Cumulus logging interval to match your station console logging interval. (Otherwise you may activate the 'feature' in the Davis stations where they send the entire contents of the data logger when Cumulus asks for the data since it was last running). See Readme.txt. For other station types, normally set so matches station console logging interval, but this is not mandatory. For other makes as Cumulus on restarting is able (see next parameter) to read logged data from your station you can choose to match Cumulus and station logging intervals, then the frequency of logged information will be same regardless of whether Cumulus is running continuously or restarted (this improves accuracy of any averages calculated). Some Cumulus users set this Cumulus logging interval to be one of the two shorter times so they retain the maximum measurement detail in case of any need to correct rogue measurements, but have set their station logging interval at a longer time so that the station does not overwrite the memory locations over the longest period they might be away. In this case, the frequency of logged information will change between the periods Cumulus is running and the catch-up readings from station logger when it is restarted, and all averages calculated will be less accurate if Cumulus is not running all the time.
UseDataLogger=1	Cumulus 1.x.y: Selected in the Station Configuration Screen Settings block. Cumulus MX: This parameter (attribute=value) is added directly to the file in the [Station] section if you want to change the default, it does not appear on the settings screen. 0 = Disabled, at start-up, Cumulus will not download data from the station's data logger (if it has one) but just start with next observations. 1 = Enabled (Default), at start-up Cumulus will download data from the station's data logger (if it has one) to catch up from the point where Cumulus was last shut down. See last parameter for advice re station logging interval.
WindUnit=0	Wind speed measurement unit used by Cumulus (as selected in the Units block of Station settings screen within Configuration menu) 0 = m/s 1 = mph 2 = km/h ("kph" prior to version 1.8.3) 3 = kts These are the labels that Cumulus applies on its screens and web pages, most weather stations can only output in one unit (e.g. dm/s for Fine Offset). If that is not the unit selected here, Cumulus will ensure the values are converted to that selected from the 4 listed during processing.
PressureUnit=0	Pressure_Measurement unit used by Cumulus (as selected in the Units block of Station settings screen within Configuration menu) 0 = mb 1 = hPa 2 = in These are the labels that Cumulus applies on its screens and web pages, most weather stations can only output in one unit (e.g. hPa for Fine Offset). If that is not the unit selected here, Cumulus will ensure the values are converted to that selected from the 3 listed during processing
RainUnit=0	Rain_measurement unit used by Cumulus (as selected in the Units block of Station settings screen within Configuration menu) 0 = mm 1 = in These are the labels that Cumulus applies on its screens and web pages, most weather stations can only output in one unit (e.g. dm for Fine Offset). If that is not the unit selected here, Cumulus will ensure the values are converted to either of the 2 listed during processing
TempUnit=0	Temperature measurement unit used by Cumulus (as selected in the Units block of Station settings screen within Configuration menu) 0 = Celsius 1 = Fahrenheit These are the labels that Cumulus applies on its screens and web pages, most weather stations work in one unit (e.g. for Fine Offset a positive integer (a 12 bit value) that uses 0 at -40 degrees Celsius/Fahrenheit and 500 at 10 degrees Celsius/50 degrees Fahrenheit; i.e. you get the actual temperature in Celsius by subtracting 400 and dividing by 10). If that is not the unit selected here, Cumulus will ensure the values are converted to either of the 2 listed during processing
LocName=	A Name for the location (as entered on the same screen as other parameters) - used for title of tab in browser and main heading on each standard web page
LocDesc=	A Description for the location (as entered on the same screen as other parameters) - inserted after 'Welcome to ' on 'Now' web page.
StartDate=13/08/2009	This parameter is automatically inserted into Cumulus.ini and given a value when Cumulus is first run. By default this will be set to the date of initial installation of the Cumulus application (whichever flavour). See FAQ#I_have_inserted_pre-Cumulus_data_making_.27Records_began_on.27_date_wrong
CreateWxnowTxt=0	This parameter (attribute=value) is added directly to the file in the [station] section, it does not appear on a configuration screen. If the parameter is not included in the file, the default value is assumed. 0= turn off creation of wxnow.txt file (stored in main Cumulus folder) 1= (default) create wxnow.txt file (an alternative way to get data to CWOP/APRS)
ListWebTags=0	This parameter (attribute=value) is added directly to the file in the [station] section, it does not appear on a configuration screen. If the parameter is not included in the file, the default value is assumed. 0= (default) turn off creation of WebTags.txt file (stored in main Cumulus folder) 1= create WebTags.txt file when Cumulus is restarted (contains an unordered list of all the web tags your Cumulus build will recognise and process)
LastLoggerDownload=13/08/2008 12:48:52	The date/time of the last down load from your weather station (note: no longer used, so only present if you used an early Cumulus 1 version); Later Cumulus 1 builds and all 2 and MX builds use [[today.ini] to track date/time. This date/time (regardless of whether this parameter is present) is available on your website by using <#LastDataReadT>
RainSeasonStart=1	Selected in the same settings page as other parameters. The month (1 to 12) of the year that is used as the start of the annual 'rain season'. Default = 1 meaning January.
YTDrain=0	Selected in the same settings page as other parameters. Year to date correction if starting part way through rainfall year (see previous parameter). Value is entered in your current Rain_measurement units. Default is 0.
YTDrainyear=0	Selected in the same settings page as other parameters. The year for which the previous parameter (YTDrain) is to be applied. Default is 0 meaning not applied to any year. Note if you selected a month other than January in "RainSeasonStart" parameter, you will need to change this "YTDrainyear" when the calendar year changes during your first 'rain season' and change it to 0 when you reach the same "RainSeasonStart" month and start your second 'rain season'.
RainDayThreshold=-1	This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. If the parameter is not included in the file, the default value is assumed. The threshold value which the daily rainfall has to equal or exceed for the day to be considered a 'rain day'. Default -1 = 0.2mm or 0.01in. Value is entered in your current Rain_measurement units.
NoFlashWetDryDayRecords=1	This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. When set to 1 stops new Longest Wet/Dry Period records being 'flashed'
UseCumulusForecast=0	Selected in the same settings page as other parameters, if selected Cumulus will generate a simple weather Zambretti forecast, if your station does not supply a forecast, or as an alternative to the one supplied by your station. See the Forecast webtag for more information. See next parameter for interval between forecast updates. 0 = Disabled (default) 1 = Enabled
HourlyForecast=0	Selected in the same settings page as other parameters, applies only if Cumulus is set (see previous parameter) to generate a forecast (see FAQ#My_forecast_says_.22Not_available.22), 0 = Disabled, (default) Cumulus will use Zambretti Forecaster every time it updates the web pages. 1 = Enabled, this setting causes the forecast to be updated only once an hour (on the hour).
UseCumulusPresstrendstr=0	Selected in the same settings page as other parameters. If selected Cumulus will generate the name for the current pressure trend, e.g. "Falling", "Rising quickly" etc, instead of the one supplied by your station. The names used are those in the UK Shipping Forecast. Note that some stations do not supply this anyway, so setting this has no effect (Cumulus always generates the names for those stations). 0 = Disabled 1 = Enabled
FCPressureThreshold=0.1	This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. It specifies the threshold (in mb per hour averaged over 3-hour period) for a pressure change to count as rising or falling rather than steady when determining the Zambretti forecast. The default is 0.1 mb/hr averaged over the previous three hours. If the parameter is not included in the file, the default value is assumed.
FCpressinMB=1	Selected in the same settings page as other parameters. The units you use here are not related to the units you use for pressure (PressureUnit=x parameter earlier) in Cumulus; the option is given here simply as a convenience for the next two parameters. 0 = inches of mercury 1 = mb
FClowpress=950	Low Pressure extreme limit (in units specified by previous parameter). Selected in the same settings page as other parameters in the Forecast area, using either millibars or inches of mercury. Default is 950mb
FChighpress=1050	High Pressure extreme limit as entered in the same Forecast area as last 2 parameters. Default is 1050mb
CloudBaseInFeet=1	Cloud base measurement unit as selected in same screen (here from version_1.8.8) as other parameters. In MX you cannot change the default without adding this directly into file with MX stopped. 0 = metres 1 = feet (default)
RTdisconnectcount=N	This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. By default, the 'realtime' ftp connection stays connected. If the parameter is not included in the file, the default value is assumed. You can make it disconnect periodically by adding an Option to periodically disconnect the realtime FTP connection, the theory being that it will not get stuck if the server dies, and will keep trying to reconnect. N must be a positive integer. For example set N to '60'; it represents the number of realtime ftp uploads between disconnections - so 60 would give an hour if 1 minute realtime interval selected.
Logging=1	This parameter (attribute=value) determines if when you next start Cumulus it will send enhanced information to the debug file. Set it to 1 to enable this. Debugging can also be switched on while you are running Cumulus of any flavour. By default, enhanced debugging will stop when you exit Cumulus and the value will be reset to 0.
ErrorLogSpikeRemoval=0	This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. ??keeps the number of messages in the error log window to a maximum of 256?
UVdecimals=0	This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. UV values are now displayed and logged as whole numbers by default. You can change this by adding this entry specifying the number of decimal places. (added 1.9.3 build 1038) 0 = Integer Values (default) n = Number of decimal places e.g. 1
NoSensorCheck=1	This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. If the parameter is not included in the file, the default value is assumed. The option (for 'incomplete' stations) to disable the sensor check described in this FAQ 0 = Sensor check enabled (default) 1 = Sensor check disabled
Cumulus 1 only
Port=0	Selected in the Station Configuration Screen Settings block. Com port in your computer which is connected to your weather station if connected via a serial port. Defaults to port 0. This parameter is ignored by MX, best to remove it, MX uses a Comport parameter instead, see #Parameters_changed section above.
SpecialLog=1	This optional parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. If the parameter is not included in the file, the default of no special log is assumed. Add this entry to start updating a file called 'speciallog.txt' in the data folder with the following fields: date(dd/mm/yy),time(hh:mm),inside temp,inside humidity,inside dew point,outside temp,outside humidity,outside dew point See forum
Cumulus MX only
RecordSetTimeoutHrs=24	From version 3.5.1, Cumulus MX will set new records (available in Extreme Records Web Tags) from the time of the record until a timeout value (default 24 hours). You can change the default timeout by adding this parameter, and changing the default '24' to the number of hours that suit you. This parameter is not available in any earlier versions.

Davis family specific:

These settings apply to Cumulus 1.9.x, check with release notes for your version and previous versions to see all settings applicable to any earlier version you use. Some of the settings below apply to Cumulus MX too, but check the MX support forum to check if individual ones do or do not apply.

• For example 'Port=' is specific to Cumulus 1.
• 'DavisRainCollectorModel' is not available to Cumulus MX users as that does not use the DLL interface.
• At time of writing "RestartIfDataStops" is not available to MX users.

"The DLL" is a Windows Dynamic Link Library supplied by Davis for third parties to use when writing software for Davis stations. It handles fetching data from the console, and does all kinds of useful things like converting the data into the units you require.

ADDITIONAL CUMULUS MX parameters - see beta page here.

Parameter Line Entry	Function
[Station]	Section name - the following parameters relate to the station configuration.
Both Cumulus flavours - in MX edit in Station Settings, for Cumulus 1 edit in Station Configuration Screen
DavisRainCollectorModel=X	This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. (Available from Build 1096 of version 1.9.4) Option to specify rain collector model for Davis stations for situations where the Davis DLL is unable to read it from station, and your rain figures in Cumulus are incorrect as a result (can happen when using Virtual VP, for example). Value X is an integer from 0 to 5 with the following meanings: 0 = 0.1 inch 1 = 0.01 inch 2 = 0.2 mm 3 = 1 mm 4 = 'other' inch 5 = 'other' mm Davis have not documented what calculations the DLL does for options 4 and 5. If this line is not included in cumulus.ini the DLL will use whatever type the station tells it to use
ForceVPBarUpdate=0	Set this in the Station Configuration Screen Settings block. Select to force the Vantage Pro (and Pro2) barometer to update once a minute instead of the default 15 minutes. Note that you may not need this, more recent stations already update every minute 0 = Disabled 1 = Enabled
SyncDavisClock=0	Set this in the Station Configuration Screen Settings block where called Synchronize station clock. When set, at Cumulus start-up and at a fixed time (default 04:00, see next parameter) each day, Cumulus will set the Davis VP/VP2 clock to within a minute of the same time as the PC. (From build 3015 for MX). 0 = Disabled, default (as deselected on the Station Configuration Screen) 1 = Enabled, ensures that when Cumulus asks the station for data since time X, both recognise X!
ClockSettingHour=4	Configuration file only setting, controls what hour of the day the SyncDavisClock activity will take place if it is enabled. 4 = 04:00 (default value) 0-23 = 00:00 to 23:00
VP2ConnectionType=1	Weather station connection type that is selected in the Station Configuration Screen Davis type block 0 = serial (see next parameter to specify COM port) (1 = usb - setting no longer available on screen, remains as default in cumulus.ini for those not using a Davis) 2 = TCP/IP (see later parameters to specify ports) Default is type 1, i.e. neither option on screen selected, so if you use a Davis you must select either serial or TCP/IP..
Port=0	Set this in the Station Configuration Screen Serial Port block. Identifies COM Port used if Davis type is serial. Default is 0.
VP2TCPPort=22222	Set this in the Station Configuration Screen Davis TCP/IP Settings block. Comunications port used if VP type has TCP/IP selected. Default is 2222
VP2IPAddr=0.0.0.0	Set this in the Station Configuration Screen Davis TCP/IP Settings block. Weather station IP address if VP type has TCP/IP selected. Default is 0.0.0.0
VP2SleepInterval=500	This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. This is the period which Cumulus waits between reads of the data from Davis stations, the value is in milliseconds. The default is 500 ms; if you suspect that data is being missed, you could try reducing this figure. For VirtualVP users, tests revealed that VP2SleepInterval = 1100 seems to work the best. It updates every two seconds with few exceptions. See note in readme.txt about VP2SleepInterval - in v1.9.3 release it is around line 50. Related FAQ: FAQ#My_Davis_station_shows_a_higher_maximum_wind_speed_than_Cumulus
VPClosedownTime=x	This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. x is the number of seconds after the start of the re-connect attempts that you want the program to close itself (added v.1.8.5 b.726).
VP2PeriodicDisconnectInterval=0	Set this in the Station Configuration Screen Settings block with the Discon period value. When the clock minute changes, Cumulus stops the current stream of data from the console, disconnects, waits for the specified number of milliseconds, to allow the Weatherlink IP to briefly connect to the Davis Weatherlink site. Cumulus then attempts to reconnect. Set it to zero to disable, if you are not using the Weatherlink site.
DavisCalcAltPress=1	This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. Davis stations calculate Sea Level Pressure from Station Pressure using a formula based on several parameters such as temperature, humidity, etc, rather than just using altitude as most other stations. CWOP require 'Altimeter Pressure' to be uploaded, i.e. a value calculated simply using altitude. Note for MX, use of the LOOP2 (see here) means s.l.p. can be obtained from the Davis station. The following note applies to Cumulus 1.x.x: The station does not provide this value directly, nor the station pressure, so Cumulus 1.x.x has to read some extra data once a minute in order to do the calculation. This can take several seconds, so it means that a 'normal' data reading may be missed. If you don't use CWOP, or you are happy for Cumulus to send Sea-Level pressure to CWOP (the difference is small unless you are at high altitude), set this value to 0. Cumulus will then use the Sea-Level Pressure value instead of the Cumulus calculated Altimeter Pressure. 0 = Disabled 1 = Enabled (default)
LogExtraSensors=0	This is set in the Settings block on the Station settings screen off the configuration menu. Set this to 1 if you have additional sensors (e.g. a Davis Leaf Wetness probe) to make Cumulus read, display, and log the readings from the sensors. You don't select this for Solar/UV sensors.
RestartIfDataStops=0	This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. Cumulus 1 attempts to restart itself if it has had no data from the station for 60 seconds. Davis stations can use this option explained in the La Crosse table if Cumulus sometimes fails to read information from the logger. As it says in the help, it may not fix the connection problem, but at least it stops Cumulus logging, so once you have fixed the problem it will download the missing data when you start it up again.

Introduced for problems with Fine Offset family:

• These parameters were introduced for Cumulus to cope with Fine Offset stations and their clones, but a few of the parameters below may be found to be useful more widely.
• Some parameters are set on screens, other attributes do not appear in the cumulus.ini file unless they are added using an external editor, but the values still have a recommended default value as explained below.

Parameter Line Entry	Function
[Station]	Section name - the following parameters relate to the station configuration.
RestartIfUnplugged=0	This is set in the settings frame on the Station settings screen off the configuration menu. 0 = Disabled, default i.e. deselected on the Station Configuration Screen 1 = Enabled, Cumulus will restart if it detects that a Fine Offset station is unplugged. Note: Unless the station has been manually plugged in again, a Cumulus restart has no benefit; normally the station should be checked to be plugged in before Cumulus is ever started and the station then left plugged in.
SyncFOReads=0	This is set in the settings frame on the Station settings screen off the configuration menu. 0 = Synchronisation disabled, default (Cumulus reads the memory without taking into account when memory is being updated) 1 = Re-synchronizes once each day, to avoid reading memory at time of memory update A Fine Offset station will be writing to its memory every 48 or 60 seconds (depending on model); Cumulus can attempt once a day to identify when this update of memory occurs, and thereafter try not to read the memory at update time, by using what is called a synchronisation mode of operation. See next parameter.
FOReadAvoidPeriod=3	Add this line to cumulus.ini [Station] section if you wish to change the default, this parameter used to fine-tune the previous parameter. 3 = default value Sets the interval (in seconds) during each 48 (or 60 for some models) second of station logging period when Cumulus will avoid reading the station data to try and minimise lock ups. If the clock drifts more than this value in 24 hours, then Cumulus may cause the station to lock up when reading the data. The actual station clock drift gets logged to the diags file when the re-synchronise (see last parameter) takes place, this will give an idea of whether it would be useful to adjust this setting.
ReportLostSensorContact=0	Add this line to cumulus.ini [Station] section 0 = reporting off 1 = reporting on (default) Option to turn off reporting of 'lost sensor contact' for Fine Offset stations. (added Cumulus 1.9.4 b.1070)
UseZeroBearing=0	Selected on same screen as other parameters. Intended for weather stations that do not supply a wind bearing, so Cumulus has to calculate it from reported compass direction. 0 = Disabled, Cumulus displays the current bearing read from the station (i.e. the last direction the wind was blowing from before it became calm). Note that the average wind bearing will always display zero bearing if there has been no wind for the last N minutes (where N is defined by previous parameter if present but defaults to 10), as the average bearing takes wind speed into account. 1 = Enabled, Cumulus display a bearing of zero (and '---' for the compass point) when the wind is calm (note when not calm, bearing is 360 for true North)
EWdisablecheckinit=0	Add this line to cumulus.ini [Station] section if application gets stuck when Cumulus starts up connected to a Fine Offset (clone) station (added Cumulus version 1.9.2, build 1011). 0 = Disabled, default, it checks the first two bytes of the Fine Offset station's memory. 1 = Ignores part of memory (see FAQ#When_I_start_Cumulus.2C_I_get_the_error_message_.22The_station_is_not_initialised.22).
EWduplicatecheck=0	Add this line to cumulus.ini [Station] section if application gets stuck in the download stage. Introduced in version 1.8.5 (b.630) to deal with certain bytes being given the same value in first and second line. 0 = Disabled, default, Cumulus accepts all bytes from the Fine Offset station's memory. 1 = Ignores part of memory (see this forum thread). For example one problem is that "55 AA" repeats at the start of the second line of data. Those bytes are only supposed to appear at the start of the first line (or so I am told).
EWpressureoffset=x.y	Add this line to cumulus.ini [Station] section Got a pressure problem with a Fine Offset station when the pressure 'offset' that Cumulus reads is garbage, so Cumulus just uses zero? Tell Cumulus what offset to use, by using an external text editor to insert this parameter where x.y is your pressure offset in in mb or hPa [i.e. your station (absolute) pressure subtracted from the sea-level (relative) pressure].

Spike Removal

• 7 of the 10 spike removal parameters listed below are adjusted in the frame at the bottom of the Calibration screen, off Configuration menu, they have a prefix of EW because they were introduced for dealing with problems seen in the Fine Offset family; the corrections are only applied when Cumulus is reading directly from the station at a very frequent interval, spike removal does not apply when Cumulus is re-started and is transferring observations from the station logger to the Cumulus monthly log.
• The other 3 spike removal parameters have to be entered directly in cumulus.ini, none of these ones can be set on the 'calibration' screen.
• As Cumulus does not check station type before applying any of these settings, ensure for Davis stations (these do not have spike problems) the spike removal filters are set to the defaults shown below.
• However, spike removal correction may be implemented for La Crosse stations, they can have problems with their PC interface, using the same EW filter settings listed below.

Parameter Line Entry	Function
[Station]	Section name - the following parameters relate to the station configuration.
EWMaxRainTipDiff=30	Add this line to cumulus.ini [Station] section Cumulus (1 and MX) has a configurable threshold for the maximum feasible amount of rain between updates (i.e. within 48-seconds on Fine Offset stations without solar, 60 seconds on those measuring solar), set in units of count of tips. Default=30 tips, as each tip represents 0.3mm this is equivalent to 9 mm or just over a third of an inch in 48 seconds. This setting affects rain rate, rain last hour, rain so far today (and what is recorded in today.ini/dayfile.txt), but does not affect the web tag <#r24hour>.
EWmaxHourlyRain=999	This is set in the spike removal frame on the Calibration settings screen off the configuration menu. An hourly rain count 'spike removal' filter for weather stations that do not supply this figure so Cumulus has to calculate it. Any changes in calculated value, between one calculation and the next, greater than the value specified here will be ignored by Cumulus when it calculates the hourly rain total. Cumulus ignores this parameter if the weather station directly supplies this figure to Cumulus. 999 is the default indicating no spike removal required.
EWmaxRainRate=999	This is set in the spike removal frame on the Calibration settings screen off the configuration menu. A rain rate 'spike removal' filter, changes in calculated value, between one calculation and the next, greater than the value specified here (set in calibration screen of configuration menu) will be ignored by Cumulus when it calculates the rain rate. Cumulus ignores this parameter for other makes of weather station (they supply a rain rate to Cumulus). The default value of 999 also effectively makes Cumulus ignore spike removal.
EWgustdiff=999.0	This is set in the spike removal frame on the Calibration settings screen off the configuration menu. A wind gust 'spike removal' filter, changes in calculated value between one calculation and the next, greater than the value (always metres per second) specified here (with a default of 999.0) will be ignored by Cumulus.
EWwinddiff=999.0	This is set in the spike removal frame on the Calibration settings screen off the configuration menu.. A wind speed 'spike removal' filter, changes in calculated value between one calculation and the next greater than the value (always metres per second) specified here (with a default of 999.0) will be ignored by Cumulus
EWpressurediff=999.0	This is set in the spike removal frame on the Calibration settings screen off the configuration menu. A pressure change 'spike removal' filter, changes in read value, from one reading to the next, off any station greater than the value (always mb) specified here (with a default of 999.0) will be ignored by Cumulus
EWminpressureMB=900	Add this line to cumulus.ini [Station] section Cumulus will ignore all pressure readings from the station that are less than this value (units are always hPa/millibars)
EWmaxpressureMB=1200	Add this line to cumulus.ini [Station] section Cumulus will ignore all pressure readings from the station that are greater than this value (units are always hPa/millibars).
EWTempdiff=999.0	This is set in the spike removal frame on the Calibration settings screen off the configuration menu. A temperature change 'spike removal' filter. Replace default of 999.0 with the maximum difference in degrees Celsius (the units Cumulus uses for all calculations regardless of what you select for display) you are prepared to accept between successive data readings.
EWhumiditydiff=999.0	This is set in the spike removal frame on the Calibration settings screen off the configuration menu. A humidity change 'spike removal' filter, changes in read value from any station greater than the value (as %) specified here (with a default of 999.0) will be ignored by Cumulus.

Reading File instead of weather station

Requiring Cumulus to read Easyweather.dat instead of a station directly perhaps for Stations not recognised by Cumulus

• Stations not recognised by Cumulus may be set to create an EasyWeather_Format file. For these the first two (or three) parameters below are mandatory.

Parameter Line Entry	Function
[Station]	Section name - the following parameters relate to the station configuration.
EWInterval=0	This parameter is entered in the Station Configuration Screen Settings block. 0= Default, meaning not applicable n= any positive decimal value representing Easyweather version 6.2, or earlier, logging interval in minutes (used for reading single latest observations from Easyweather software output). Note to specify seconds, use decimal minutes, e.g. 30 seconds = 0.5 Note: If you have not set Station Type to 4, then Cumulus ignores this parameter, i.e. it only applies if Cumulus needs to know how often to read a new record from the easyweather.dat file.
EWFile=	This is set in the settings frame on the Station settings screen off the configuration menu. Easyweather.dat or EasyWeatherPlus.dat file path/name as entered in the Station Configuration Screen Settings block (Station Type is set to 4). Note: This approach is viewed as outdated, it was used if obsolete EasyWeather software version 6.2, or earlier, was running at same time as Cumulus software, both ran all the time, and Cumulus was required to simply process the latest record on the database, at the interval set in previous parameter, without all the additional processing Cumulus is able to do if it is reading directly from the console very frequently. (attribute and equals sign, but no value)= Default (Station Type not set to 4). Note: This is the default when Cumulus is operating normally. (attribute and equals sign, but no value)= Default (Station Type is set to 4). Note: If you want to run Cumulus without an attached weather station (because your station has a fault or because you have a second PC), it is possible to run Cumulus with station Type=4 but with the default of no file specified in this parameter. The full Cumulus directory structure and its files including those in the data sub-directory are needed (kept from when your station was working or copied from the PC with the station). Although only the old observations can be accessed, (no new ones are being added), this does allow analysis of the old observations via all Cumulus features such as View This period and View Select-A-Graph. See FAQ here for reduced functionality using Cumulus in this way.
LogExtraSensors=0	This is set in the settings frame on the Station settings screen off the configuration menu. 0 = Disabled (default) 1 = Enabled; Use if you a) have Fine Offset models (generally those models 3xyz) with Solar/UV sensors, and b) Type=4 set in that parameter (see top of [station] section), and c) EWFile=path/EasyWeatherPlus.dat set in previous parameter. Only relevant if all these conditions met. Note: Cumulus uses this parameter to determine where to find each observation (e.g. outside temperature, wind speed, humidity etc.) in the latest file record. If you set this parameter wrong, Cumulus will assign what it finds in various field locations wrongly and therefore it is highly likely that temperatures, wind speeds and everything else will appear to have many rogue values in Cumulus but look okay on the weather station console display. This parameter is also used for other makes of weather station, see the relevant section for your make as the parameter is used differently.

Oregon Scientific specific:

Parameter Line Entry	Function
[Station]	Section name - the following parameters relate to the station configuration.
Humidity98Fix=0	Selected in the Station Configuration Screen Settings block. 0 = Disabled (default) 1 = Enabled, humidity displayed and recorded as 100% if your sensor registers a relative humidity of 98% or greater. Normally only useful for Oregon Scientific stations.
LogExtraSensors=0	This is set in the settings frame on the Station settings screen off the configuration menu by the Extra Sensors selection. 0=Disabled (default) 1= Enabled - Used for Oregon Scientific WMR-928 and similar stations if you have additional sensors (e.g. another temperature probe) to make Cumulus read, display, and log the readings from those sensors. You don't use this for Solar/UV sensors. (Note this attribute appears in Davis family and Fine Offset family tables above and in Instromet station specific: table below with different usage explanations).
WMR928TempChannel=N	This line needs to be added in the [Station] section of the Cumulus.ini file for WMR-928 stations (and other serial stations using the same protocol, eg WMR-968) to use an 'extra' channel (see previous parameter) as your main temperature sensor, set N to the required channel
WMR200TempChannel=N	This line needs to be added in the [Station] section of the Cumulus.ini file for WMR200 stations (and any other Oregon Scientific USB stations which work with Cumulus, e.g. WMR100) to use an 'extra' channel as your main temperature sensor, set N to the required channel

La Crosse specific:

NOT AVAILABLE IN CUMULUS MX - at time of writing "RestartIfDataStops" is not available

Parameter Line Entry	Function
[Station]	Section name - the following parameters relate to the station configuration.
WS2300Sync=1	This line needs to be added in the [Station] section of the Cumulus.ini. This makes Cumulus check the time that the station is going to communicate with the sensors, and synchronises all of its reads to be 2.5 seconds after that. Experiments have shown that this does not help the bad data situation.
LCMaxWind=X	This line needs to be added in the [Station] section of the Cumulus.ini. It is setting for the La Crosse max wind speed, where X is the maximum (uncalibrated) wind speed in m/s that you want to allow. The value you supply should be in metres/second, regardless of what wind unit you are using in Cumulus.(V1.8.8 Build 874 on)
WS2300IgnoreStationClock=0	This line needs to be added in the [Station] section of the Cumulus.ini. Option to ignore the La Crosse station clock on logger download. 0 = Disabled (default) 1 = Enabled
RestartIfDataStops=0	This line needs to be added in the [Station] section of the Cumulus.ini. Option for Cumulus 1, it attempts to restart itself if it has had no data from a La Crosse station for 60 seconds i.e. if data from station stops. This may fix whatever the problem is; it may not. But it should at least stop the same data being repeatedly logged. 0 = Disabled (default) 1 = Enabled
ReportDataStoppedErrors=0	This line needs to be added in the [Station] section of the Cumulus.ini. Option to turn off reporting of 'data stopped' errors to the Cumulus error log (may be needed with La Crosse stations) 0 = Disabled (default) 1 = Enabled

The spike removal parameter listed in the Fine Offset section above, may also be used with La Crosse stations.

Hydreon specific:

All 6 of these parameters are set on RG11 screen within configuration menu, see its Help for more information.

Parameter Line Entry	Function
[Station]	Section name - the following parameters relate to the station configuration.
RG11port=1	Specifies the COM port to use for Hydreon RG-11 rain detection devices. 1 = COM1.
RG11TBRmode=1	Specifies the Hydreon RG-11 rain device mode of operation. 0 = Rain detection mode - "It's Raining" 1 = Tipping bucket mode.
RG11tipsize=0.01	Specifies the tipping bucket size for Hydreon RG-11 rain detection devices. The 'tip size' must be specified in the units that you have configured Cumulus to use for rain.
RG11port2= RG11TBRmode2= RG11tipsize2=	Settings to connect a second Hydreon RG-11 rain detection device. Note that you must have one RG-11 set to "It's raining" mode and the other to "tipping bucket" mode. Cumulus does not validate this.

Instromet station specific:

Parameter Line Entry	Function
[Station]	Section name - the following parameters relate to the station configuration.
ImetWaitTime=200	This parameter (attribute=value) if you need to change it from its default of 200 ms is added directly to the file, it does not appear on a configuration screen. Specifies the time in milliseconds that Cumulus allows for a response from an Instromet station. If you are having problems with reading from an Instromet station, try inserting this line into the Station section using a value of 500. According to the specification, 500 ms is the absolute maximum time that the station should take to respond to any command.
SyncDavisClock=0	Set this in the Station Configuration Screen Settings block where called Synchronize station clock. Note despite the name of the parameter within 'Cumulus.ini', this does apply to Instromet stations. When set, at Cumulus start-up and at 04:00 each day, Cumulus will set the Instromet clock to within a minute of the same time as the PC 0 = Disabled, default as deselected on the Station Configuration Screen 1 = Enabled, ensures that when Cumulus asks the station for data since time X, both recognise X as representing same time!
LogExtraSensors=0	This is set in the settings frame on the Station settings screen off the configuration menu by the Extra Sensors selection. If you have 'extra sensors' selected, the wet bulb reading will be used as an extra temperature sensor. Otherwise it is used as 'wet bulb' and the humidity will be calculated from that and the dry bulb sensor. 0=Disabled (default)- . For a wet bulb sensor, Cumulus will output the humidity, not the temperature shown by the wet bulb. 1= Enabled - Used for optional Sunshine hours or extra temperature sensors on Instromet stations. For a wet bulb sensor, Cumulus will output the temperature it shows, but not calculate the humidity. (Note this attribute appears in Davis family, Oregon Scientific specific and Fine Offset family tables above with different usage explanations).

Section: Offsets

Set most of these parameters in Cumulus 1 (available from version 1.8.1 onwards) using the Configuration menu and Calibration screen, the exception is 'TempMult2'.

Set these parameters in MX under the Settings tab using the Calibration screen, again excluding second order multipliers.

Parameter Line Entry	Function
[Offsets]	Section Name - the following 'attribute=value' parameters are the adjustment factors for your specific sensors
Both Cumulus flavours
TempOffset=Offset_Value	Default 'Offset_Value' is 0 in this parameter, used for quadratic formula shown below
TempMult=1	First order multiplier by which measured outdoor Temperature is to be corrected (default=1). For formula see next item.
TempMult2=0.0	This line needs to be added in the [Offsets] section of the Cumulus.ini, if it is omitted default multiplier is 0.0. "Second order" multiplier by which measured outdoor Temperature is to be corrected, this means that the logged reading can be (TempMult2 X measured-temp X measured_temp) + (TempMult X measured_temp) + TempOffset
HumMult=1	Multiplier by which measured Humidity is to be corrected (default=1). See formula in next row
HumOffset=Offset_Value	Default 'Offset_Value' is 0 in this parameter used for formula: Cumulus Humidity = measured_Humidity X Humidity_multiplier + 'Offset_Value'
WetBulbMult=1	First order multiplier by which measured Wet Bulb Temperature is to be corrected (default=1). See formula in next row
WetBulbOffset=0	Default 'Offset_Value' is 0 in this parameter, used for formula: Cumulus wet bulb temperature = measured_wet_bulb X wet_bulb_multiplier + 'Offset_Value'
WindDirOffset=Offset_Value	Default 'Offset_Value' is 0 in this parameter used for formula: Cumulus Wind Bearing = Measured Wind Bearing + 'Offset_Value'
InTempOffset=Offset_Value	Default 'Offset_Value' is 0 in this parameter used for formula: Cumulus Indoor Temperature = Measured Indoor Temperature + 'Offset_Value'
WindSpeedMult=1	Multiplier by which measured Average Wind Speed is to be corrected (default=1). e.g. Officially in UK the wind speed is measured with sensors at 10m above ground level. If your sensor is not at 10m AGL then a correction multiplier should be applied using the following formula V10/Vh = 1/(0.233 + 0.656*log10(h+4.75)) where "h" is your sensor height in meters so if your anemometer is 5m off the ground, V10/Vh comes out at 1.134
WindGustMult=1	Multiplier by which measured Wind Gust Speed is to be corrected (default=1).
PressOffset=Offset_Value	Default 'Offset_Value' is 0 in this parameter, used for formula: Cumulus pressure = Measured Pressure + 'Offset_Value'
RainMult=1	Multiplier by which measured Rainfall (and therefore rainfall rate too) is to be corrected (default=1).
UVMult=1	Multiplier by which measured UV to be corrected (default=1). see formula in next row
UVOffset=Offset_Value	Default 'Offset_Value' is 0 in this parameter used for formula: Cumulus UV level = Measured_UV_level X UV_multiplier + 'Offset_Value'
Cumulus 1 only
DavisCalcAltPressOffset=Offset_Value	Default 'Offset_Value' is 0 in this Davis Altitude parameter, used for formula: Cumulus altimeter pressure = Calculated Altimeter Pressure + 'Offset_Value' The calculated altimeter pressure (from build 792) uses k1 := 0.190284; // discrepency with calculated k1 probably because Smithsonian used less precise gas constant and gravity values k2 := 8.4184960528E-5; // (standardLapseRate / standardTempK) * (Power(standardSLP, k1) Result := Power(Power(absolute_pressureHPa - 0.3, k1) + (k2 * elevationM), 1/k1); Sea level pressure is strictly calculated from actual pressure making compensation for temperature and humidity variation with height and most stations supply a SLP, but in Cumulus terms where a station supplies absolute pressure only, a standard offset is used to correct that to sea level pressure. Altimeter pressure as used for reporting to APRS/CWOP, does not make this compensation for temperature and humidity, it assumes standard atmosphere, purely a compensation for altitude, so the above calculation is used, then this offset is used by Cumulus to re-calculate altimeter pressure.
Cumulus MX only
PressMult = 1.0	Cumulus MX only from version 3.2: First order multiplier by which measured Pressure (in above formula) is to be corrected (default=1).
SolarMult=1.0	Solar multiplier
SolarOffset=0.0	Solar offset

Section: Web Site

Applies to both flavours of Cumulus:

• Both parameters edited in Cumulus 1 using the Internet Configuration screen Sites/Options tab Web Site block.
• Both parameters edited in MX using Internet Settings screen within Web/FTP site section.

Parameter Line Entry	Function
[Web Site]	Section Name - the following parameters relate to your website
ForumURL=https://cumulus.hosiene.co.uk/	A website forum URL
WebcamURL=http://www.sanday.org.uk/webcam/webcam.php	URL for your Webcam

Section: FTP site

NOTE: For MX, the word site should be in lower case as shown in left-hand column heading and above.

See individual entries for how to modify these parameters (either select on a screen, or edit file directly). Where the modification can be done on a screen, the Cumulus Help screens (e.g. Configuration: Internet) will explain the selection.

This Wiki discusses the most basic of these settings on simple web site set up page and discusses the more complex ones in this section of Customised templates.

Parameter Line Entry	Function
[FTP site]	Section Name - the following parameters relate to your website FTP parameters
Both Cumulus flavours - in MX edit in Internet Settings, see individual entry for Cumulus 1 edits
Logging=0	Determines whether enhanced "debugging" logging takes place where Cumulus 1 or MX makes a detailed record of each action that takes place. 0 (default) = Cumulus 1 or MX will not add debug logging. 1 = For debug logging when Cumulus 1 or MX (re-)starts, add Logging=1 to the station section of Cumulus.ini while Cumulus is stopped. In MX only, it can also be set in the admin interface internet settings screen. Note that if set on the admin interface, it only remains set while Cumulus continues to run, and resets to default off when MX re-starts. For MX, if you want debugging output every time it runs, then add "-debug" parameter as explained at Parameter_for_adding_debugging
DailyProgram=	In Cumulus 1, set in the Daily box of Internet option of Configuration menu, Sites/Options tab in External Programs block. The name (including path) of a command-line program to be run once a day, after the daily 'rollover' has been performed. default - none
DailyParams=	In Cumulus 1, set in the Params box alongside the Daily box of Internet option of Configuration menu, Sites/Options tab in External Programs block. default - none The corresponding 'parameters' for 'DailyProgram' used to specify any parameters to be passed to that command.
Host=	In Cumulus 1, set in the Internet option of Configuration menu, Sites/Options tab in web site block. This is either the name, or the IP address, of the ftp server to which you connect when you upload pages to your web site. You probably used it with an external FTP program when you followed the instructions in the Cumulus Help, Readme.txt, or Simple_Website_setup. If you host your web site yourself, then "Host=localhost" might be appropriate. Leave blank, "Host=", if you are not using ftp, but simply creating the output files on your pc with a Copy instruction.
Port=21	In Cumulus 1, set in the Internet option of Configuration menu, Sites/Options tab in web site block. Port used for FTP upload, default as shown is the normal port.
Username=	In Cumulus 1, set your web site FTP log-in Username in the Internet option of Configuration menu, Sites/Options tab in web site block
Password=	Shows your web site FTP login password as entered in the Internet option of Configuration menu (note: this is not encrypted)
Directory=	In Cumulus 1, set in the Internet option of Configuration menu, Sites/Options tab in web site block. Directory (including path) on your server to which FTP will upload the files. value is left Blank, default, the root position specified by ftp server (see Host above) A path from the starting point as the position specified by ftp server (see Host above)
IncludeSTD=1	In Cumulus 1, set in the Internet option of Configuration menu by the Include Standard Files at the top of Files Tab screen 0 = Disabled 1 = Enabled, (default) the standard web files provided with Cumulus will be processed and uploaded at each automatic or manual web update to the FTP root or any 'Directory' you have specified (see above).
AutoUpdate=0	In Cumulus 1, set in the Internet option of Configuration menu in Web Settings block of Sites/Options tab as Auto Update. 0 = Disabled, an upload will only occur if Web upload is selected manually either from the File menu or the right click menu if Cumulus is minimised. 1 = Enabled, Cumulus will automatically upload your processed web pages to your web site at regular intervals (as specified by the 'Update Interval ' - see below) using FTP to the directory as specified in 'Directory' (see above).
FTPlogging=0	Set (Cumulus 1) by selecting FTP Logging in Configuration menu, or by adding this line to 'FTP site' section of Cumulus.ini. 0 (default) = Cumulus will not store messages from FTP server. 1 = Cumulus will show the messages sent to, and responses from, the FTP server. Cumulus 1 stores this output in a separate FTP log file " ftplog.txt ". MX stores this output in the same MXDiags file as other diagnostics, it does not use that separate file. Also MX allows use of alternative secure protocols instead of standard FTP, and this parameter is ignored for secure transfers.
MaxFTPconnectRetries=3	Set in this config file only. Allow configurable max FTP connect retries (default is retry up to 3 times).
ActiveFTP=0	In Cumulus 1, set in the Internet option of Configuration menu in Web Settings block of Sites/Options tab as Use active FTP mode. 0 = Disabled (default) 1 = Enabled, Cumulus will use 'active' FTP mode instead of the default 'passive' mode. You should only select active mode if you are having problems with FTP uploads.
FTPRename=0	In Cumulus 1 (available from version 1.8.1), set in the Internet option of Configuration menu in Web Settings block of Sites/Options tab as Use FTP rename. 0 = Disabled (default), no name change after uploading onto the server 1 = Enabled, the new update is loaded using temporary names, files are renamed on the sever afterwards
DeleteBeforeUpload=0	In Cumulus 1, set in the Internet option of Configuration menu in Web Settings block of Sites/Options tab as Delete before upload. 0 = Disabled (default) 1 = Enabled, files are deleted from sever before the new update is loaded
UpdateInterval=15	In Cumulus 1, set in the Internet option of Configuration menu in Web Settings block of Sites/Options tab in Interval box. The interval in minutes at which you wish Standard (not real-time) updates (either FTP to your website, or copy to a local directory on your pc) to automatically occur. Default 15 minutes.
ExternalProgram=	In Cumulus 1, set in the Program box of Internet option of Configuration menu, Sites/Options tab in External Programs block. The name (including path) of a command-line program to be run at the 'normal' web update interval, after all of the other processing has been performed.
ExternalParams=	Selected in the Params box alongside the Program box of Internet option of Configuration menu, Sites/Options tab in External Programs block. The corresponding 'parameters' for 'ExternalProgram' used to specify any parameters to be passed to that command.
EnableRealtime=0	In Cumulus 1, set in the Internet option of Configuration menu in Web Settings block of Sites/Options tab as Enable Realtime. 0 = Disabled (default) - If you do not have Auto Update option set (top of Web Settings block), the realtime.txt file is not created/updated. - If you have the Auto Update option set (and a suitable Interval configured), Cumulus will create the realtime.txt file at that specified normal update Interval (not the Real-time Interval) It only creates the file (any previous creation is lost) at that interval, but you can separately specify it as an extra file to upload during the 'normal' upload, or just use it for any other purpose on your PC. 1 = Enabled, Cumulus will add a timer that allows you to upload at a more frequent interval than the standard upload interval set above Cumulus will create a new realtime.txt file at the Real-time Interval (Note that neither Cumulus 1 nor Cumulus MX use this file in standard features, but it can be fed to other software that requires frequent values updating) - Other parameters need to be set for more actions.. The realtime.txt file contains various weather parameters and was used by the CumulusRealtime.swf (shock wave flash) real time wind gauges (as on the supplied 'gauges' web page for early versions of Cumulus 1.x.x). Shockwave flash software was withdrawn some years ago, so this usage ceased. This parameter controls whether the file is created, the next 2 parameters control how and whether it is uploaded.
RealtimeFTPEnabled=0	In Cumulus 1, set in the Internet option of Configuration menu in Web Settings block of Sites/Options tab as Enable Realtime FTP. 0 = Disabled (default), without FTP it is only possible to upload files at the realtime interval if the required remote location is on same device as that running Cumulus. 1 = Enabled, Cumulus will establish an FTP connection to your web site, so that the realtime.txt file, and any other files you specify, can be uploaded when realtime processing takes place. The 'EnableRealtime' setting must be set to 1 for this setting to have any effect. - If you have the RealtimeFTPEnabled option set, and a suitable RealtimeInterval configured, (for second of these see below) Cumulus will upload the realtime.txt file to your web site, after the number of seconds specified by RealtimeInterval (see that parameter below) since any previous upload
RealtimeTxtFTP=0	In Cumulus 1, set in the Internet option of Configuration menu in Web Settings block of Sites/Options tab as Realtime.txt FTP. When set to 1 Cumulus will upload the realtime.txt to your web site during realtime processing. The 'EnableRealtime' and 'RealtimeFTPEnabled' settings must both be set to 1 for this setting to have any effect.
RealtimeInterval=15 RealtimeInterval=30000	Set in the Internet option of Configuration menu in Web Settings block of Sites/Options tab as Realtime Interval. The time between uploads of the realtime.txt file, and any other files associated with real-time interval, (i.e. a new upload of files will begin this number of seconds after the last upload has ended). If you set it to 15 seconds and it takes say 10 seconds for any uploads, it will not be until the time it takes plus another 15 seconds has elapsed that it does the next upload (i.e it starts 25 seconds after last start). If you set it to 5 seconds, and it takes say 10 seconds for any uploads, while you won't actually get an upload every 5 seconds, it will always attempt the next upload within 5 seconds of the previous one ending, so it starts approximately every 15 seconds. Note the difference in default value between the two flavours as shown in previous column.
RealtimeProgram=	In Cumulus 1, set in the Realtime Program box of Internet option of Configuration menu, Sites/Options tab in External Programs block. The name (including path) of a command-line program to be run at the 'realtime' web update interval, after all of the processing has been performed.
RealtimeParams=	In Cumulus 1, set in the Params box alongside the Realtime Program box of Internet option of Configuration menu, Sites/Options tab in External Programs block. The corresponding 'parameters' for 'RealtimeProgram' used to specify any parameters to be passed to that command.
Cumulus 1 only
IncludeSTDImages=1	Set in the Internet option of Configuration menu of Cumulus 1 by the Include Standard Images at the top of Files Tab screen. 0 = Disabled 1 = Enabled,(default) the standard image files generated by Cumulus 1 (moon, graphs, etc) will be uploaded at each automatic or manual web update to a sub-folder of the 'Directory' you specified called 'images'.
ResizeGraphs=0	Set in the Internet option of Configuration menu in Web graphs block. 0 = Disabled (default) Cumulus uploads the default 750 x 300 pixel graphs. 1 = Cumulus resizes the large graph images when creating them for upload to your web site. Specify the required height and width in the corresponding boxes of same Web graphs block (see below for related parameters). Note that the images are simply scaled to the new size; there will be some loss of quality.
GraphHeight=300	Graph height, default is 300 (pixels) - see previous parameter
GraphWidth=750	Graph width, default is 750 (pixels) - see ResizeGraphs parameter
ImageFolder=	Set in the Internet option of Configuration menu by the Copy Images to folder at the bottom of Files Tab screen. value is blank (default) no action Path and file name in LOCAL folder to which the generated image files are also copied after each upload, either at manual web update and the 'normal' automatic interval, or the 'real time' interval, depending on next parameter. Used if you want backups of generated images. See Cumulus Help.
ImageCopyRealtime=0	Set in the Internet option of Configuration menu by the Realtime? at the bottom of Files Tab screen. 0 = (default) the generated image files are copied at each manual web update and automatically in 'normal' interval 1 = the generated image files are copied in 'real time' interval.
IncludeSolarChart=0	Set in the Internet option of Configuration menu by the Solar at the top of Files Tab screen. 0 = Disabled (default) 1 = Enabled, the optional solar graph image file generated by Cumulus will be uploaded at each automatic or manual web update to a sub-folder of the 'Directory' you specified called 'images'.
IncludeUVChart=0	Set in the Internet option of Configuration menu by the UV at the top of Files Tab screen. 0 = Disabled (default) 1 = Enabled, the optional UV graph image file generated by Cumulus will be uploaded at each automatic or manual web update to a sub-folder of the 'Directory' you specified called 'images'.
IncludeSunshineChart=0	Set in the Internet option of Configuration menu by the Sunshine at the top of Files Tab screen. 0 = Disabled (default) 1 = Enabled, the optional sunshine graph image file generated by Cumulus will be uploaded at each automatic or manual web update to a sub-folder of the 'Directory' you specified called 'images'.
Both Cumulus flavours - in MX edit in Internet Settings, see individual entry for Cumulus 1 edits
ExtraLocalxx=	Where 'xx' varies between 0 and 99; used to specify path to local file that is to be optionally processed by Cumulus, then to be copied or FTPed to another location at interval indicated You can use "<currentlogfile>" (all versions of Cumulus 1 or MX) on its own to represent the name of the standard log file that is currently being used. For Cumulus 1, only 0 to 9 are set in the Internet option of Configuration menu by an entry in the Local column of the table on the Files Tab screen, 10 to 99 have to be inserted manually by adding parameter lines to the configuration file, they cannot be entered on any Configuration screen. All of 0 to 99 are added using "Extra web files" screens in the settings menu of the admin interface. From build 3087, MX also allows you to use "<currentextralogfile>"to specify the name of the extra sensor log files being currently used.
ExtraRemotexx=	Where 'xx' varies between 0 and 99; used to specify path to remote file that is created by Cumulus, by being copied or FTPed from local location set above at interval indicated below. You can use "<currentlogfile>" (all versions of Cumulus 1 or MX) on its own to represent the name of the standard log file that is currently being used, or as part of another file specifier if you want a different destination file to be used each month (so those for previous months are not overwritten). For Cumulus 1, only 0 to 9 are set in the Internet option of Configuration menu by an entry in the Local column of the table on the Files Tab screen, 10 to 99 have to be inserted manually by adding parameter lines to the configuration file, they cannot be entered on any Configuration screen. All of 0 to 99 are added using "Extra web files" screens in the settings menu of the admin interface. From build 3087, MX also allows you to use "<currentextralogfile>"to specify the name of the extra sensor log files being currently used.

You can choose which sub-folder (default 'images') in the MX internet settings page
ComportName=/dev/ttyUSB0	This parameter (attribute=value) can be added directly to the file with MX stopped, but it is best to set the serial port name in the MX admin interface. If you have moved from Cumulus 1 to MX, and for some reason you want to edit Cumulus.ini, note that the item called ComportName has to be added for MX and that it is a string, for the full device name, e.g. COM1 or /dev/ttyUSB0; while the Cumulus 1 'Port' parameter which is just an integer is no longer needed and should be deleted from the file.
DisableFtpsExplicit=0	(Add to Cumulus.ini file, no option in station settings screen) Default 0 use Explicit FTPS; Change to 1 to use Implicit mode

Section: Display

Set the majority of these parameters using Configuration menu and either Display or Colours screens as seen on link and indicated below. The exception is "TwelveHourClock", that parameter is set by clicking on the displayed time.

The only settings used in this section by Cumulus MX are "NumWindRosePoints" and those for extras.

Parameter Line Entry	Function
[Display]	Section heading - the following parameters affect how the main screen looks.
Heading=My Weather	Title Heading on the Main Screen. Set in the Display Configuration Screen General block
SavePosition=0	Set in the Display Configuration Screen General block. 0= default, each time Cumulus 1 starts the main window will be displayed in the middle of the main, or only, monitor connected to your pc 1= the current position of the main window will be saved to Cumulus.ini#Section:_MainForm when Cumulus closes, and the window will open again at that position the next time Cumulus starts. This will place it on any monitor connected to your PC.
StartMinimised=0	Set in the Display Configuration Screen General block. 0= default, the main window will be displayed on the main or only monitor connected to your pc 1= If set to 1, Cumulus will start with the main window minimised, either to the system tray or the task bar, depending on the 'MinimizeToTray' setting (see next parameter).
MinimizeToTray=0	Set in the Display Configuration Screen General block 0 = Disabled (default), Cumulus will minimise to the task bar 1 = Enabled, causes Cumulus to appear as an icon in the system tray when it is minimized. The icon will flash if a record is broken or an error occurs. Double click on the icon to restore the main window (or right click on the icon and use the pop-up menu).
ForecastCentred=0	Set in the Display Configuration Screen General block. 0 = Disabled, (default) Forecast appears left justified on main screen below sun and moon details 1 = Enabled, Forecast appears centred horizontally on main screen below sun and moon details

The heat index is calculated only if the actual temperature in the shade (not in direct sunlight) is above 27 °C (80 °F), so normal temperature shown here for cooler temperatures. 1 = Enabled, calculated Humidex value to be displayed on the main screen instead of Heat Index. (Note that Cumulus displays degrees C or F for Humidex, whereas strictly speaking it is unitless. This is for the convenience of those who use Fahrenheit but would still prefer to see Humidex displayed, where it might be confusing to show the unconverted value.)
DisplaySolarData=0	Set by Display solar/extra data item in the Display Configuration Screen General block. 0 = Disabled (default) 1 = Enabled, adds an extra panel to the main screen below the recent extremes panel - EITHER Panel displays Temp, Dew pt and Hum (this extra sensor data, can be populated from Oregon WMR-928 stations, see next 3 parameters) OR Panel displays Evapotranspiration (ET), Ultraviolet (UV) and Solar radiation if station Type is Vantage Pro and solar data is available

[Windy]	Section Name
Enabled=0	This tick box is used if you want to export to Windy.com, default is disabled.
APIkey=	Here you enter the API key you are given when you create a Windy account, default is null. If you have an account, this is a very long string, so paste it in carefully!

CatchUp=1	When you restart MX, if the weather station allows it, MX will read "catch-up" readings from the station's logger, the default is to send these to Windy.com. Untick this box if you don't want past values to be sent.

Section: NOAA

All these can be set in the NOAA Setup Screen in Configuration menu. You might select to close Cumulus, and edit the 'NOAATempNorm[Jan-Dec]' and 'NOAARainNorm[Jan-Dec]' parameters by using a external editor to manipulate into required format, copy, and paste, the values from another source (as there are a lot of figures to type in).

Please note: because this section of Cumulus.ini uses date format parameters, it is not directly exchangeable between Cumulus 1 and Cumulus MX. You will need to update this section using the NOAA Setup Screen in Configuration menu.

Parameter Line Entry	Function
[NOAA]	Section Name - the following parameters are set from the NOAA Setup dialog in Cumulus
Name=	Your NOAA Station name
City=	NOAA location city
State=	NOAA location state/county/province or the equivalent in your nation
12hourformat=0	Use 12 or 24 hour time format in the reports 0 = 24 hour format (default) 1 = 12 hour format
HeatingThreshold=65	The base temperature which is to be used to calculate heating demand as heating degree days. The default is 65 degrees if you use Fahrenheit scale or 18.3 degrees if you use Celsius. The value you type on the NOAA Setup Screen is entered in the units that you have selected for temperature. Degree days are calculated on a minute-by-minute basis and the totals for each day are stored in dayfile.txt. Changes to the threshold values cannot therefore apply retrospectively. But, if the dayfile.txt entry doesn't have the degree days in it, then it uses the day's average temperature to produce a 'simplified' heating or cooling degree days figure (but obviously never both at the same time) and in that case it does use the current threshold settings.
CoolingThreshold=65	The base temperature which is to be used to calculate chilling demand as cooling degree days. The default is 65 degrees if you use Fahrenheit scale or 18.3 degrees if you use Celsius. The value you type on the NOAA Setup Screen is entered in the units that you have selected for temperature. Degree days are calculated on a minute-by-minute basis and the totals for each day are stored in dayfile.txt. Changes to the threshold values cannot therefore apply retrospectively. But, if the dayfile.txt entry doesn't have the degree days in it, then it uses the day's average temperature to produce a 'simplified' heating or cooling degree days figure (but obviously never both at the same time) and in that case it does use the current threshold settings.
MaxTempComp1=27	The value used in the reports for the counts of days with max temperatures above the specified temperature.
MaxTempComp2=27	The value used in the reports for the counts of days with max temperatures below the specified temperature.
MinTempComp1=0	The value used in the reports for the counts of days with min temperatures below the specified temperature.
MinTempComp2=-18	The value used in the reports for the counts of days with min temperatures below the specified temperature.
RainComp1=0.2	The value used in the reports for the counts of days with rain totals greater than (or equal to) the specified amount.
RainComp2=2	The value used in the reports for the counts of days with rain totals greater than (or equal to) the specified amount.
RainComp3=20	The value used in the reports for the counts of days with rain totals greater than (or equal to) the specified amount.
AutoSave=0	If set, when Cumulus does the end of day reset, it will auto create NOAA-style reports for the month and year corresponding to the day which has just ended.
NOAAUseUTF8=0	(Added in Cumulus 1.9.4 beta build 1078) Specifies the 'Character set' in which NOAA reports are generated whether automatically (by Cumulus just after rollover) or manually (by selecting Save in NOAA Monthly/Annual Reports screen within Edit menu). 0 = Uses the encoding used for the viewer's operating system's default ANSI code page. 1 = Uses UTF8 (UCS Transformation Format—8-bit) format - the dominant character encoding for the World-Wide Web as using one to three bytes it represents most characters in common use covering most languages.
AutoFTP=0	If set, when Cumulus does the first FTP upload after the daily reset, it will also upload the latest auto-created monthly and yearly NOAA-style reports. Note that you must already have regular (non-realtime) FTP configured.
MonthFileFormat="NOAAMO"MMyy".txt"	Defines the format of the filename used for the monthly reports, using date formatting characters (see Webtags#Time.2FDate_.27format.27_Parameter). For Cumulus 1, the two digit month can be represented by 'mm', but as 'mm' represents minutes in MX, MX (recent versions) changes any 'mm' it finds into 'MM'. The default uses a 2 digit number for the month, but you may prefer the full month name or an abbreviation in your language. Note that any characters which are not date formatting characters should be in double quotes.
YearFileFormat="NOAAYR"yyyy".txt"	Defines the format of the filename used for the yearly reports, using date formatting characters (see Webtags#Time.2FDate_.27format.27_Parameter). Note that any characters which are not date formatting characters should be in double quotes.
FTPDirectory=	The FTP directory into which Cumulus will attempt to upload the latest NOAA-style reports. You must give the full path from the point of login, and do not supply a trailing 'slash'. Note that the directory must actually exist on the server.
	These 'climatic normal' values are set from the NOAA Setup dialog in Cumulus, but could be set up by processing information in a spreadsheet
NOAATempNorm[Jan-Dec]=-1000	Long term temperature averages for each month, used for 'departure from the norm' calculations. '-1000' is used to represent Null, a parameter that has not yet been set
NOAARainNorm[Jan-Dec]=-1000	Long term rainfall averages for each month, used for 'departure from the norm' calculations. '-1000' is used to represent Null, a parameter that has not yet been set

Section: Solar

Set mostly in solar block at foot of Station Settings screen.

Parameter Line Entry	Function
[Solar]	Section Name - the following parameters are set from the Solar Setup dialog in Cumulus
SunThreshold=75	If you have a solar sensor: Cumulus tries to determine whether the sun is shining by determining whether the current solar radiation value is above a certain percentage of the current theoretical maximum. The value you supply here is used as that percentage. The default value is 75%.
RStransfactor=0.8	Cumulus uses the Ryan-Stolzenbach formula to determine the current theoretical maximum solar radiation at your location at the current moment in time. This formula has a factor to allow for the transmission of the radiation through the atmosphere; the default is 0.80.
SolarMinimum=0	This setting allows you to specify a minimum solar radiation value which needs to be reached before it can be considered to be sunny. Note that this setting does not replace the calculation using the current theoretical maximum, it specifies an additional condition which has to be met. This setting therefore allows you to cater for the periods at the beginning and end of the day when the theoretical maximum is very low.
LuxToWM2=0.0079	Edit cumulus.ini to add this parameter if you have a Fine Offset station with a solar detector. These supply 'Lux' values rather than 'W/m2' values that Davis stations supply. Cumulus attempts to convert from Lux to W/m2 using the supplied multiplication factor. You can add this parameter if you want to use a value other than the default of 0.0079, which is the generally accepted standard conversion factor for sunlight.
UseBlakeLarsen=0	Called B/l on screen. Set this to 1 if you have a Blake-Larsen Sun Recorder, and you want Cumulus to get today's sunshine hours from it. You need to configure the Blake-Larsen software to put the SRsunshine.dat file into the Cumulus data folder so that Cumulus can read it.

MQTT

MQTT (Message Queuing Telemetry Transport) is a machine-to-machine (M2M), also known as "Internet of Things", connectivity protocol.

This section is only applicable to Cumulus MX and only available from version 3.5.0 (build 3071)

Most settings are on the Internet Settings screen in either the MQTT section or one of the two Send message sections (the section is named for each parameter), but as indicated one requires editing Cumulus.ini while MX is stopped.
