[[File:Crystal Clear info.png|40px]] This page was last updated for the MX release in July 2020; that is no longer latest!
 
=History of this page=
Appeal to contributors: Please work through all MX release announcements and work out all the many updates needed for this page, it may even need a redesign for more recent releases!
</div>
 
From release 3.10.1, the way that settings are changed, and the settings available have changed so much, that information previously on this page was misleading.
 
Anybody using an earlier MX release (3.0.0 to 3.9.7) should now go to [[Cumulus.ini(MX_3.0.0_to_3.9.7)|this page]]
[[File:Badge vMx.png]] This page now only applies if you are using Cumulus MX.
 
TheAnybody information forusing the legacy Cumulussoftware has(e.g. been1.9.4) movedshould tonow thego newto [[Cumulus.ini ini_(CumulusCumulus_1)|this 1)page]] page.
 
The past history for both those two new pages remains available via the history tab on this page.

=Content of this page=
= Introduction =
 
This page has been emptied ready for new content to reflect how MX works from 3.10.1 onwards.
[[Category:Cumulus MX]]
*'''Cumulus.ini''' is a text file containing initialization parameters used by the Cumulus MX application.
*It is '''only read''' when Cumulus MX starts up.
**When Cumulus MX is run for very first time, the file does not exist, as it is not included in the download (of either flavour).
** if this is the first run of the software, part of what it does will create the file for first time.
***In the case of that first run, the file will exist when it ''shuts down''
** 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.
*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
**In early versions of MX, there were some "read-only" parameters, these cannot be configured within Cumulus, but were retained if they were in any previous copy of the file.
*Note any Cumulus MX save action may change the order, or add lines, compared to any file that you manually edited.
*In some versions of MX, 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 biggest change in 3.10.1 was to revise where settings are changed, and how the web pages used to change settings can vary what they show based on an earlier selection on that page. A related change is that all settings are made via the [[MX Administrative Interface|Admin interface]]. (In earlier releases, "read-only" settings were made directly in the "Cumulus.ini" file, while "read-write" settings were made either in the file or via the interface).
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.
 
Settings are now arranged according to the menu selections, as that is the way you change them.
 
Consequently, the revised tables have to explain which section settings are in the file.
 
=The Cumulus.ini file=
==Is this documentation definitive?==
 
'''Cumulus.ini''' is a text file containing initialization parameters used by the Cumulus MX software application.
The short answer to that question is that it is likely this documentation has not been kept up to date!
 
When Cumulus MX is run for very first time, the file does not exist, as it is not included in the release distribution.
<big>Anybody with a log-in for this Wiki can edit this page, and your contribution to improving this article is welcomed.</big>
 
When MX is restarted, it reads the ''Cumulus.ini'' that now exists. The settings it finds tell it what options you have selected and which sections of the MX code apply for your selections of weather station type (input) and for your selections of what processing it should do, and where you want it to send weather data to (output).
The only rules are to follow existing table layout where possible,
* add any new parameters to the correct sub-section
* create a new sub-section if the correct sub-section does not exist
* the default value should be shown in first column,
* the explanation should be in second column
** use bullets where there is a choice of values
** say what release introduces any new parameter
 
The file is a simple text file. It is divided into sections with section names in square brackets (e.g. [Station]).
 
Within each section, there are parameters. Each parameter is in format '''Attribute=Value''', and appears on a line to itself. The parameters, within a section, can be in any order.
*Cumulus.ini uses '''sections''', thus the first way that the list is divided is by the relevant section where the parameter must be placed
** Some sections can take a lot of parameters, and for these sub-sections may be added, that allow you to navigate directly to them from the table of contents
** A parameter may be defined in multiple sub-sections, if its definition needs to be explained differently according to weather station types
*As explained later, in past MX releases, some parameters are read-only, and some are read-write
**To make it easier to navigate larger tables, read-only and read-write parameters may be grouped under relevant sub-heading within the table
***A parameter may be read-only in earlier releases, but read-write in later releases, this means some parameters may not be where you first expect them to be
 
If a new release of MX adds new parameters, then they will be automatically added to Cumulus.ini when you access that setting.
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.
 
Some parameters have a default value, and you need to find the appropriate setting to change that value. However, others have an initial illegal value, and you are forced to give these parameter a valid setting before MX will allow you to save settings (and these "missing" values will stop MX doing any weather data processing).
 
=The settings pages in admin interface=
'''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.'''
 
Please see [[MX_Administrative_Interface#Changing_Settings]] for basic information, including how to load the admin interface.
It is intended that any additions made to the list will indicate which release made that extra parameter available. Therefore this page should help you whatever MX release you are running.
 
==Program settings==
Originally, there was a separate page [[Cumulus.ini (Beta)]] used for MX, when Steve Loft was developing MX and kept it in Beta.
 
===Accessibility===
When Mark Crossley took over MX development he brought it out of Beta, and from then onwards this page has tried to cover MX as well as the original Cumulus software, because the two flavours don't use the same parameters, there are a lot of complications in trying to ensure this page does completely cover MX.
 
'''The configuration parameters available in MX are often changed by a new release'''.
*Any new read-write parameters introduced by a new release will be added to "Cumulus.ini" when you close MX, but unless someone manually adds them to this article they will not be documented here. However, the default for those read-write parameters might not agree with your preference.
**Hopefully, new parameters are listed in a release announcement, but sometimes you may need to look in a topic with contributions from both users and the developer.
 
 
 
== Beta builds ==
 
Steve Loft kept MX in beta while he was developing it, during that period what applied to MX was placed in the [[Cumulus.ini_(Beta)|Cumulus.ini Beta article]].
 
After Mark Crossley took over development of MX he ended that beta. All information that was on the beta page was moved into this page, originally created for the legacy Cumulus (1) software, but the legacy information was subsequently moved to another page (see reference at top of this page).
 
When Mark is producing a new major version of MX he typically issues it in beta to a restricted number of users by email, he does not make any beta release public. For this reason, it is not anticipated there is going to be any use of the [[Cumulus.ini_(Beta)|Cumulus.ini Beta article]] while Cumulus 3 (MX) continues to develop, although of course a Cumulus 4 is in development and we wait to see what might happen when that is ready for a public release.
 
 
== 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. In the latest release build, all available settings are set within the [[MX_Administrative_Interface| Administrative Interface Settings Pages]]. You may need to work through the settings pages to ensure that any new settings are reflecting your preferences.
 
= 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 running an old release that allows 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_dealing_with_interfaces_to_external_sites|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.
 
== Creating Configuration File ==
 
When you download Cumulus MX, ''there is no configuration file included in the download''. So when you first use the software, 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.
 
 
#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: [[File:MX first start.PNG]]
#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.
# At this stage, MX creates a very basic Cumulus.ini with the default settings (shown below).
#Open the [[MX Administrative Interface|admin interface]], and select the station settings if necessary: [[File:MX_station_settings.png|800px|center]]
#At the very minimum, you must select a station type and units (as shown in image here)
#Optionally, move down the page, entering more settings, or move to other settings pages accessed from the menu seen in the image
# 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.
# 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.
#Restart Cumulus MX, it will save your settings on exit, it will read your new settings on re-starting, it will 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 (there is a way to modify [[today.ini]] so it can read what is in the separate logger), it will read (and from time to time log) the live data while MX remains running.

== Configuration File names ==
 
=== Configuration file created when first installing Cumulus MX ===
 
For those who are not swapping from Cumulus 1, their first use of MX will create a file called ''Cumulus.ini'' found in the same directory as CumulusMX.exe.
 
The file will contain an entry for every setting in the admin interface. Each entry will be a parameter in format '''attribute=value''' and the values will be as per defaults except for those which you have edited when first setting up MX.
 
These parameters are known as read-write parameters because they can be altered with the settings pages.
 
 
Note in particular, that some settings (such as units, date/time formats) must be got right first time. If you do change those later, it is a lot of work because you will need to edit all the other files that Cumulus creates to reflect those changes.
 
For Cumulus MX, if it is being run for the first time and it does not inherit a file, it needs some settings before it can do anything. Consequently, MX just hangs, because unless you look at the Terminal output or the file it creates in [[MXDiags_folder]], you won't know it is waiting for settings. You need to start up the[[MX_Administrative_Interface| Administrative Interface]] and go into the various settings pages yourself to select what MX needs to continue to work. You then need to stop MX so it stores those settings and can use them next time it starts.
 
Please note some settings can take immediate effect while MX is running, others only take on their new values when MX is restarted. Don't ever edit the configuration file directly while Cumulus MX is running!
 
Should you accidentally delete Cumulus.ini, or should you close MX badly so it does not manage to correctly save the entire contents of Cumulus.ini, MX has an advantage in that it saves Cumulus.ini into the backup folder every time it restarts and every time it does a rollover.
 
 
= File Contents =
 
The section called "[FTP site]" should obey that use of capitals and lower-case. Other sections should be named as shown.
 
<big>Please be aware that as there are frequent changes to Cumulus MX, the snapshot shown here represents an out of date release and may not cover all the parameters now available.</big>
 
Please look at MX release announcements in the support forum for all releases since July 2020, as they may contain changes not shown below. Volunteers are sought who are able to work as hard as the developer in maintaining this article (and others) in the Wiki to keep up with the frequent releases.
 
 
== 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: Station ===
 
<big>THE FOLLOWING SUB-SECTIONS NEEDS TO BE REWRITTEN - MX has changed, and the sub-sections below reflect older releases where some parameters were read-only (not set with admin interface) and some were read-write (set within admin interface)</big>
 
The difficulty is ensuring this Wiki page continues to help people whichever MX release they are using - the alternative is to split this page and have references to other pages (one for early MX releases, one for 3.10.1 onwards)
 
=== Spike Removal ===
 
Which parameters are available from this section depends on release of MX being used, and which type of station you use.

| Set to 1 to make this (and other pages) appear in a layout that is more friendly on an accessibility basis. Leave it at zero for a legacy look.
|Cumulus 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. For other weather station types, this parameter may be irrelevent.
 
MX default has not been defined anywhere
 
For standard Fine Offset rain gauges, each tip represents 0.3mm, so 30 tips are 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
|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
|A rain rate 'spike removal' filter, ''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 rain rate.The default value of '''999''' effectively makes Cumulus ignore spike removal.
|-
|EWgustdiff=999.0
|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
|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

|-
|EWminpressureMB=900
|Cumulus will ignore all pressure readings from the station that are less than this value (units are always hPa/millibars)
 
As the bug re reading pressure readings was corrected, this parameter is irrelevent in recent MX releases.
|-
|EWmaxpressureMB=1200
|Cumulus will ignore all pressure readings from the station that are greater than this value (units are always hPa/millibars).
 
As the bug re reading pressure readings was corrected, this parameter is irrelevent in recent MX releases.
|-
|EWTempdiff=999.0
|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
|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.

|ErrorLogSpikeRemoval=0
|Following applies before version 3.7.0:
*Default is zero as shown, disabling the spike removal feature.
*Add this line to file with Cumulus MX stopped, and set to 1 for the spike removal feature to be enabled.
Following applies from version 3.7.0 :
*the default for new installs is now 1.
* change to zero if you don't want this feature. It can be set from the calibration settings screen. It controls the logging of both data spikes and data limits being exceeded. Recommended to be turned on.

The second table below contains those read-write parameters that existed for Cumulus 1 and I believe are understood by MX, plus some read-only parameters mentioned in MX release announcements up to June 2020, no monitoring of subsequent announcements was made, and the details shown below may not be accurate.
 
From 3.10.1 onwards, MX has these settings in its admin interface, although they may be under sections called "Advanced" and be displayed with warnings saying don't use unless you understand! (In-between releases have additional read-only parameters that nobody ever documented here (or in subsequent sub-sections).
 
3.0.0 beta MX, plus other early releases of Cumulus MX up to 3.6.12: The read-only parameters listed here must be entered directly into the configuration file. Stop Cumulus before editing this file using any plain text editor.

|colspan="2" style="background:pink;"|Read-only parameters - The parameters listed below must be entered directly into file with Cumulus stopped.
|-
|AvgBearingMinutes=N
|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).
|-
|UseWindChillCutOff=1
|If you have not asked Cumulus to calculate wind chill, this parameter is irrelevant as it cannot affect how your weather station calculates wind chill.
 
If you have asked Cumulus to calculate wind chill ('''CalculatedWC=1'''), regardless of whether you have a weather station that can supply it, then Cumulus will by default only modify the outside temperature if both wind speed and temperature criteria are met. This parameter must be added to the file if you want 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, and Cumulus will ignore the temperature criterion
* 1 = Enabled (default), Cumulus will use both 10°C temperature and 3 mph wind speed criteria to determine if wind chill applies. Outside the criteria,the wind chill field will simply duplicate the outside temperature field.
|-
|ChillHourThreshold=45 '''Fahrenheit only i.e. USA'''
 
ChillHourThreshold=7 '''Celsius users'''
|The temperature threshold for the calculation of [[Heat/cold_degree_days_and_Chill_hours|Chill Hours]] is specified in the units that you use in Cumulus.
If the parameter is not included in the file, the default varies depending on the units you use.
*As shown the default is exactly 45 degrees Fahrenheit if Fahrenheit is used.
*The default is exactly 7 degrees Celsius, (note that is not exactly 45<sup>o</sup>F) if you have selected Celsius.
*You can put in any value you want, with a decimal place if required
*Some people have put in the freezing-point temperature (0<sup>o</sup>C and they relabel "chill hours" to "frost hours"
|-
|ChillHourSeasonStart=10
|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). On the first day of the month specified here, Cumulus resets the cumulative chill hours that it reports to zero.
|-
|SnowDepthHour=9
|If this parameter is not included in the file, then any snow entries in the [[Weather Diary]] for a particular date will continue to be used {{Version badge 1}} in output by Cumulus 1 until 9am the next morning, when entries for the current date will apply. The default for MX is not stated anywhere, but might be the standard rollover time (https://cumulus.hosiene.co.uk/viewtopic.php?f=37&t=17919).
*Allowed values are the integers 0 to 23
*The time is constant year round, in UK "a day of snow" could (before climate change) happen in April despite that being after swapping to summer (daylight saving) time.
#What you enter here is independent of any settings for rollover time
#For meteorological reporting, snow is reported on midnight to midnight days, although snow depth is measured and reported at 9am.
|-
|CreateWxnowTxt=0
|If the parameter is not included in the file, the default value is assumed.
 
* 0= turn off creation of '''wxnow.tx'''t file (stored in main Cumulus folder)
* 1= (default) create '''wxnow.txt''' file (an alternative way to get data to CWOP/APRS)
|-
|ListWebTags=0
|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)
|-
|RainDayThreshold=-1
|If this parameter is not included in the file, the default is '''-1''' and that represents 0.2 mm or 0.01 inches.
#The parameter specifies the threshold value which the daily rainfall has to equal or exceed for the day to be considered a 'rain day'.
#Value is entered in your current [[Rain_measurement]] units.
|-
|FCPressureThreshold=0.1
|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.
|-
|ErrorLogSpikeRemoval=0
|This is read-only below version 3.7.0. Because it is now a read-write parameter, please see its entry in next section of this table
|-
|UVdecimals=0
|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:
* 0 = Integer Values (default)
* n = Number of decimal places e.g. 1
|-
|NoSensorCheck=0
|By default, Cumulus will stop working if after 6 attempts it cannot read all the standard readings from a weather station:
#temperature
#humidity
#wind speed
#pressure
This parameter allows disabling of that sensor check:
* 0 = Sensor check enabled (default)
* 1 = Sensor check disabled
|-
|PeakGustMinutes=N
| 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 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.

|style="background:lightgray;"|Section name - the following parameters relate to all weather stations.
|-
|Type= -1
|Station Type as set. 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.
*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_Format#Usage_of_easyweather.dat_fields_for_Cumulus_input_of_latest_record: |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 [[EasyWeather_Format#EasyWeatherPlus.dat| 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 [[#Introduced for problems with Fine Offset family:| 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 [[Supported_Devices#Fine_Offset|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 [[Supported_Devices#Fine_Offset_with_UV/Light sensor|Fine Offset with UV/Light sensor in Supported_Devices article]].
*8=[[WMR100-200_Protocol|WMR100]]
*9=[[WMR100-200_Protocol|WMR200]]
*10=Instromet (with optional extra solar sensors or without)
 
Added in version 3.0.0:
*11=Davis WLL
 
Added in version 3.2.0:

|-
|Model="your Model description"
|The weather station model description that you want output by the web tag &lt;#stationtype> - this does not appear in the station settings, stop MX, and add it directly into Cumulus.ini within this [Station] section.
|-
|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'. 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'. 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). See next parameter to choose unit.
|-
|AltitudeInFeet=1
|Altitude measurement unit for value in previous parameter.
*0 = metres Above Sea Level
*1 = feet ASL
|-
|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.
|-
|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)
|-
|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.
*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.
|-
|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
|-
|WarnMultiple=0
| Controls behaviour for Multiple Instances of Cumulus running on PC. Requires a Cumulus restart if value toggled, before new behaviour will take effect. Set as 'Stop 2nd instance' in Station Settings page. Not available in earliest builds of MX.
*0 = Disabled, (default) Multiple instances allowed.
*1 = Enabled, prevents multiple instances of Cumulus from running.
|-
|DataLogInterval=2
|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 you 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.
|-
|WindUnit=0
|[[Wind_measurement#Wind_Speed|Wind speed measurement unit]] used by Cumulus
*0 = m/s
*1 = mph
*2 = km/h
*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
*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
*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_(and_humidity)_measurement#Temperature_Scales|Temperature measurement unit]] used by Cumulus
*0 = Celsius
*1 = Fahrenheit
These are the labels that Cumulus applies on its screens and web pages, not related to units used by your weather stations (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)
|-
|LocDesc=
|A '''Description''' for the location (as entered on the same screen as other parameters)
|-
|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.
|-
|YTD[[FAQ#My_monthly_and.2For_annual_rainfall_totals_are_wrong|rain]]=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'.
|-
|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
|-
|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 [[Cumulus_Screenshots#Display_as_at_version_1.8.8|(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)
|-
|DataLogging=0
|This parameter (attribute=value) is ignored for MX prior to build 3018, it determines if (when you next start Cumulus) it will send enhanced information to a [[MXDiags_folder]] file about the data coming from your weather station. It is important to record here that, if you subsequently stop Cumulus, this parameter is reset to zero on exit.
*0 = default of normal output
*1 = Set it to 1 to enable the enhanced output to the log that aids debugging if there is a problem
 
*If you leave Cumulus running, you can use the settings page in the admin interface to switch this extra logging on, or off, to change the detail logged in the diagnostic file while MX is running.
*Alternatively, with Cumulus stopped, you can edit the setting in the file, and the new setting will apply for the next MX session only.
 
A related parameter is "Logging=0" see next item. That controls level of diagnostic information being logged in the diagnostics file, about the processing being done by Cumulus.
|-
|Logging=0
*0 = default of normal output
*1 = Set it to 1 to enable the enhanced output to the log that aids debugging if there is a problem.
 
|This parameter can be edited in the file, or in station settings, or by use of a parameter when starting MX. It controls whether MX stores extra diagnostic information about its interaction with the weather station.
|-
|RecordSetTimeoutHrs=24
|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.
 
From version 3.5.1, Cumulus MX will set new records (available in [[Webtags#Extreme_Records|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 (i.e. not in MX up to, and including, 3.5.0.

|-
|VP2SleepInterval=500
|This read-only parameter is the period which Cumulus waits between reads of the data from Davis stations, the value is in milliseconds. The default if the parameter has not been added manually to the file is 500 ms; if you suspect that data is being missed, you could add this parameter, manually reducing this figure. For VirtualVP users, tests revealed that VP2SleepInterval = 1100 seems to work the best. It updates every two seconds with few exceptions.
|-
|VPClosedownTime=x
| x is the number of seconds after the start of the re-connect attempts that you want the program to close itself
|-
|DavisCalcAltPress=1
|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 interface means s.l.p. can be obtained from the Davis station.
 
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)
|-
|colspan="2" style="background:lightblue;"| Read-write parameters:
|-
|SyncDavisClock=0
|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
|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
*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.
|-
|VP2TCPPort=22222
|Comunications port used if VP type has TCP/IP selected. Default is 2222
|-
|VP2IPAddr=0.0.0.0
|Weather station IP address if VP type has TCP/IP selected. Default is 0.0.0.0
|-
|VP2PeriodicDisconnectInterval=0
|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.
|-
|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.
|-
|UseDavisLoop2=1
|The current MX code uses ''LOOP2'' for two purposes. First, it uses the 'peak 10-minute gust' value, to avoid the problem where a gust might be missed, and secondly it uses the 'absolute pressure' value to make calculation of 'altimeter pressure' easier and more accurate. This is mainly used if you upload to CWOP.
*1 (default) = Cumulus MX will use the LOOP2 packet for Davis Weather Stations by default. The LOOP2 packet is supported on the VP2 with firmware version 1.90 or later, and on the Vue.
*0 = Select this if you have a Vantage Pro (i.e. the original 'VP1'), or a VP2 with pre-1.90 firmware, or if you are using Virtual VP, none of these support the LOOP2 packet.
 
Without this setting, Cumulus will revert to calculating the 10-minute gust value itself from the individual wind speed readings, but it will not currently attempt to calculate altimeter pressure correctly, it will simply use the sea-level pressure instead. This is likely to be an issue if you are at high altitude and you upload to CWOP using Cumulus MX.
|-
|DavisIPResponseTime=500
|The length of time in milliseconds which Cumulus waits to allow a response from the console to a command (i.e. a request for any kind of data) from an IP logger . Default is 500ms, see Cumulus MX forum where times up to 2000ms are suggested.
|-
|ForceVPBarUpdate=0
| Added in build 3042 (January 2017).
 
The default (value=0) is to assume standard barometer updates on Davis stations. Set to 1, by adding ForceVPBarUpdate=1 in [Station] section to force more frequent barometer updates on Davis stations. Steve says "Having checked the code, I see it asks for 20 packets from the 'LOOP2' if the barometer forcing is on, otherwise it stops receiving LOOP data after 50 packets". Note that ForceVPBarUpdate=1 is only useful on very old versions of the console firmware.
|-
|DavisIncrementPressureDP=0
|(from version 3.0.0 build 3042) A Cumulus.ini setting to turn off the 'extra' decimal place in pressure values on Davis stations. To limit the pressure to 1 decimal for mb/hPa and 2 for inHg, add this to the [Station] section
|-
|VPrainGaugeType=0
|The default is to assume that people using MM units to display rain in Cumulus have a Metric Rain Adapter fitted to their rain gauge so it tips for every 0.2mm, and those selecting inches as their unit have the unmodified 0.01" rain gauge. This parameter over-rides that assumption, but note that conversion rounding errors will then occur.
 
Specifies the units selected on your Vantage Pro Rain Gauge. Set to 0 for a 0.2mm gauge and 1 for a 0.01" gauge.
|-
|DataLogging=0
|(Build 3018 onwards). Default is 0, change to 1 for more detailed Davis logging.
*0 (default) = Cumulus MX will not add extra logging.
*1 = To add extra logging to the diags file for data received from Davis stations. Use this with care, the log will get very large.
I've also added some more diagnostics to try to find the cause of the problem where data stops being read from Davis stations. Debug logging is required to be turned on. (Build 3022 onwards).|-
|-
|AutoUpdateIpAddress=1
|default = 1, set to 0 to switch off the WLL autodetection of IP address. This is a workaround for a WLL firmware bug that does not update the IP address when it changes using DHCP.
|-
|ZeroConfig
|set this on station settings screen; to enable/disable the entry/update of the stations IP address via auto-discovery

====Introduced for problems with Fine Offset family:====
 
 
{| class="wikitable" border="1"
|-
!style="width:150px" | Parameter Line Entry
!style="width:600px" | Function
|-
|style="background:lightgray;"|[Station]
|style="background:lightgray;"|Section name - the following parameters relate to the station configuration.
|-
|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.
*2 Minimum value
*3 = default value
Sets the interval (in seconds) 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.
 
Note: I have not been able to find any interval that works. In my experience, if you use this setting, MX skips every attempt to read from the weather station, As MX is coded to make an attempt every 60 seconds, but is also coded to skip every 60 seconds plus or minus the setting here.
 
MX applies both 48 and 60 second avoidances regardless of model.
|-
|EWpressureoffset=x.y
|Got a pressure problem with a Fine Offset station when the pressure 'offset' that Cumulus reads is garbage, so Cumulus just uses zero? Early releases of MX had a bug and treated a memory byte in the Fine Offset console that is nothing to do with pressure as part of the pressure reading!
 
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].
 
May not be useful in later releases of MX that read pressure from Fine Offset correctly.
 
|-
|SyncFOReads=0
|Cumulus 1 and MX
*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.

==== Reading File instead of weather station ====
 
 
{{Version badge 1}}Functionality added from version 1.7.12 (when Fine Offset could not be interrogated via USB): '''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#Usage_of_easyweather.dat_fields_for_Cumulus_input_of_latest_record: |EasyWeather_Format]] file. For these the first two (or three) parameters below are mandatory.
{| class="wikitable" border="1"
|-
!style="width:150px" | Parameter Line Entry
!style="width:600px" | Function
|-
|style="background:lightgray;"|[Station]
|style="background:lightgray;"|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_Format#Usage_of_easyweather.dat_fields_for_Cumulus_input_of_latest_record: |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_Format#Usage_of_easyweather.dat_fields_for_Cumulus_input_of_latest_record: |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#Cumulus_isn.27t_performing_periodic_tasks.2C_like_data_logging_or_web_uploads|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 [[EasyWeather_Format#Note_on_Models|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.

|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
|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

|-
|TempMult2=0.0
|This line needs to be added in the [Offsets] section of the Cumulus.ini, if it is omitted default second order multiplier is 0.0 to ensure no second order effect.
"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
|-
|colspan="2" style="background:pink;"|Only MX (build 3045 onwards) - how to set depends on your MX release.
|-
|HumMult2=0.0
|This line needs to be added in the [Offsets] section of the Cumulus.ini, if it is omitted default second order multiplier is 0.0 to ensure no second order effect.
"Second order" multiplier by which measured outdoor Humidity is to be corrected, this means that the logged reading can be (HumMult2 X measured_hum X measured_hum) + (HumMult X measured_hum) + HumOffset
|-
|colspan="3" style="background:lightblue;"| All MX releases
|-
|TempOffset=Offset_Value
|Default 'Offset_Value' is 0 in this parameter, used for quadratic formula shown for read-only parameter
|-
|TempMult=1
|First order multiplier by which measured outdoor Temperature is to be corrected (default=1).
For formula see read-only item.
|-
|HumMult=1
|Multiplier by which measured Humidity is to be corrected (default=1). See formula in read-only parameter
|-
|HumOffset=Offset_Value
|Default 'Offset_Value' is 0 in this parameter used for formula in MX read-only parameter above
|-
|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_measurement#Wind_Speed|Wind Speed]] is to be corrected (default=1).
 
e.g. Officially in UK (and most WMO obeying nations) 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_measurement#Wind_Speed|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'
|-
|colspan="3" style="background:lightblue;"| 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
<pre>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);</pre>
 
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.

|PressMult = 1.0
|only from version 3.2: First order multiplier by which measured Pressure (in above formula) is to be corrected (default=1).

!style="width:150px" | Parameter Line Entry
!style="width:600px" | Function
|-
|style="background:lightgray;"|[Solar]
|style="background:lightgray;"|Section Name - the following parameters are set as described above
|-
|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
|this parameter applies 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 correct folder i.e. the ''' program root folder''' in MX (i.e. same folder as where "Cumulus.ini" is stored).
|-
|SolarCalc=1
|The value is set in the MX user interface when the solar calculation method is set.
*0 (default) = Ryan-Stolzenbach calculation, which uses the RStransfactor entry to tune the output.
*1 = Bras calculation, which uses the BrasTurbidity entry below to tune the output.
|-
|BrasTurbidity=2.0
|The value is set in the MX user interface when the solar calculation method is set.
*2.0 (default) = Perfect clear sky
*decimal value = The normal range is 2 (Clear sky) to 5 (Smoggy)

=== Section: NOAA ===
 
'''Please note:''' because this section of Cumulus.ini uses date formatting parameters, you are advised to read [[Reports_folder#NOAA_style_Report_Naming]].
 
Set these setting on the '''NOAA Settings''' page within Settings 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).

|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 [[Heat/cold degree days and Chill hours | 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 [[Heat/cold degree days and Chill hours | 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.

|-
|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=<big>"NOAAMO"</big>MMyy<big>".txt"</big>
|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=<big>"NOAAYR"</big>yyyy<big>".txt"</big>
|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.
|-

|-
|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
