Cumulus.ini

Please note this page was created 13 June 2021.

At last update, it shows position as at beta build 3135, (missing some changes for the 3.12.0 release build of 3141).

This new page was created to reflect parameters added to Cumulus.ini in releases 3.8.0, 3.9.2, 3.10.0, and 3.12.0 (early beta builds - June 2021). It excludes all parameters removed after release 3.7.0.

This document is 'Work In Progress' so content may not be complete.

Please be aware that information on this page may be incorrect.

Since this page describes a file whose content frequently changes, this page may be out of date, unless somebody bothers to update it for every change.

Note that 3.12.0 (when first installed) apparently automatically rewrites this file, to remove some historic parameters, and to insert some new parameters, hopefully the support forum will explain this, as it appears people are losing some settings due to this file rewrite, and have to manually add those lost preferences back.

Purpose of Cumulus.ini file

This is a text file containing initialization parameters. This page covers those used by the Cumulus MX software application.

For MX there can only to be one Cumulus.ini file, and it must be stored in the same folder as the executable "CumulusMX.exe".

The configuration settings in Cumulus.ini have the following main purposes (this list may be incomplete):

• Identify which weather station type MX is to read, and settings related to that model
• Identify which derivatives are source ones (read directly from weather station and converted to your preferred units) and which derivatives MX is to calculate for you.
• Identify where you want MX to output to (options include external web sites, and database tables)
• Control what is output to those destinations, to the extent that each can be configured

Why does this Wiki now contain multiple pages describing "Cumulus.ini"?

MX has been developed very dramatically by Mark Crossley:

1. There were minor differences between the legacy cumulus.ini (for versions 1.x.y, ending with 1.9.4) with documentation now here and the original 3.0.0 beta (previously documented on Cumulus.ini (Beta) page, but that page has been cleared)
2. The dramatic development of MX produced considerable differences between that original MX beta, and the configuration that applied up to 3.7.0, as now documented here
3. Even more dramatic changes to the MX configuration have been happening since 3.8.0, with the biggest changes at 3.9.2, 3.10.0, and 3.12.0; therefore, the decision was taken to abandon maintaining the page previously called "Cumulus.ini", and start again with a brand new empty page!

All the pages, previously called "Cumulus.ini", can be found from the owning category. The original page was preserved at Cumulus.ini_(preserving_history) so look there for its editing history. That page also expands on the above summary of why that old page was replaced by this new page.

Simplifications

The MX configuration is very different to that used by the legacy software. MX has far more optional functionality than the legacy software, therefore MX requires far more parameters to tailor all these functionality options.

The file is read into Internal Variables as Cumulus starts, and those variables are written back into the file when any settings are changed.

In the MX releases covered by this Wiki page, almost all settings are edited from a number of web pages for settings included in the local web interface.

To make it easier for the Cumulus MX user, the developer had to devise a way to make it easier to quickly assign the settings that might be best for those new to Cumulus to get the software working without needing to understand all the settings. This is achieved by introducing some "master" settings, these both determine which dependent settings are displayed, and what default values those dependent settings take. So a novice just has to get the "master" settings right and they then achieve a typical way of using that functionality! For those who are slightly more expert, full flexibility is available by adjusting the majority of dependent settings to what is required for more specialised requirements.

The ongoing development of MX is focused on making configuration even simpler, by revising the pages for the setting of all parameters, and improving the labels/grouping. By moving away from legacy software terminology and the parameters it needed; the developer has started introducing parameters and labelling that fits the MX design.

It may be worth remembering why the legacy software made life complicated:

1. There could be more than one "cumulus.ini" file for the Legacy Cumulus up to 1.9.4, as explained here.
2. The vast majority of parameters (that could appear in the file) could only be edited directly in the file.
   • To simplify the editing in-situ, the author (Steve Loft) recommended that, within any "File section" you intended to change, you sorted the parameters into alphabetical order, before editing the file.
   • That advice was given because having parameters in alphabetical order would prevent you inserting a parameter that already existed.
   • This would avoid the potential problem arising from the design that Cumulus 1 would ignore any duplicate parameter; (Cumulus would take the first one it found, and that might not be the last one you edited!)

Structure of Cumulus.ini

The file is divided into "File sections" (see terminology definitions below), each File section name is on a separate line (with no other content) and enclosed in square brackets (e.g. [Station]).

These File sections can appear in any order, by default new File sections are appended after all previous File sections, but if you prefer the File sections in another order, MX can still find them, although it may spend more time searching!

Within each File section, there are parameters. Each parameter is in format Attribute=Value, and appears on a line to itself.

The parameters, within a File section, can be in any order, by default new parameters are appended at end of the relevant File section.

How this Wiki page classifies settings

This new Wiki page is no longer designed around the way parameters appear in the file, as earlier pages with this name were. Here are some of the reasons:

1. Settings can appear in any order in the file, but it is easier to find them on this page if they are listed alphabetically
2. Releases might add new parameters, or remove old parameters, so looking at a file does not identify which parameters need to be explained on this page
3. Releases might add new sections in the file, or remove old sections in the file, so organising this page by those "File sections" no longer makes sense
4. The settings interface in MX is being comprehensively redesigned. That means this documentation cannot be organised by the way MX organises its settings pages.
   • To clarify that reason, if this Wiki page was organised according to the Settings Screens that applied say at release 3.8.0, a different sequence might be required in say 3.12.0 because that changed the Settings Screens.

Some classification is still needed to help you the reader find settings, only you can judge whether the grouping here suits you! In creating this page, I have tried to think of a way to group various settings and arranged those groups alphabetically, to make navigation as easy as I can.

Of course if you have your own ideas of a better way to group the documentation here, you are welcome to implement your preference, by editing this page.

Tabular presentation

Within the groupings I have selected, individual settings are normally presented as rows in tables for clarity on this Wiki page. The individual tables can have up to 7 columns. The columns can explain for each setting:

• Where in the admin interface you edit it (MX page and MX section in terminology below)
• Whether the Setting is always shown on the Settings Page ("Always" is shown), or is only shown if an earlier Setting has a particular selection (dependency is shown)
• What File Section (in terminology below) it appears in with the file (always appears, and is shown, between square brackets)
• The attribute name used for the parameter in the file (always shown with an equals sign after it)
• Which release introduced the setting(s)
• What is the default value for the parameter, (and what that default value means)
• A description of what the parameter represents, and what values it can take

If the content of any column would be same for every row, then that column is omitted, and the relevant information is instead stated before the table.

Exceptions to above table styling:

1. MQTT parameters are handled slightly differently, as they did not fit that standard layout
2. The mean temperatures, and normal rainfall figures, with one parameter per month, have been presented as text, rather than a table for simplicity
3. For the Extra Web Files Settings page, where the settings page uses editable grid software, instead of listing all 800 settings individually, the table here is split into just 8 rows, each of which applies to 100 parameters in the file.

Terminology used on this Wiki Page

Terminology	What it means
Qualifications: Settings page Wiki page	Because "page" could refer to either this page or the Settings page, page will always be qualified
Shown on Settings page?	Sometimes whether you see a particular setting on the Settings Page, depends on a previous selection has been made, that is explained under this heading
MX Section	Under this heading you will find how to navigate to the relevant setting within the admin interface. This covers the page where you edit the setting, followed by →, and then the section (and sub-section where relevant) that you have to select to see the setting Each MX section on the Settings page has to be opened individually (by either a button for maximum accessibility, or a Click ▶to expand, click ▼ to collapse for alternative styling).
Label on Settings page	Under this heading you will discover how MX labels the individual setting where you edit that setting
File Section	Within the file, a number of section headings are used, to gather multiple parameters together. Thus under this heading, for each setting, the table shows the File Section where the parameter will be stored
Parameter Line Entry	Within the file each setting is represented by a parameter in format attribute=value on a line to itself without any punctuation symbols. If the parameter has a default value, that is shown here and explained in next column
Default	This is the value (if any) that the individual setting takes when it has not been amended. Some parameters do not have a default value and "(none)" will be shown in this case. No brackets surround literal text representing default value, which is normally also seen in Parameter Line Entry. In general, round brackets are used in Default column to indicate an explanation.
Description	Under this heading you will find an explanation of the setting including (where relevant) what values it can take

When, and How, does MX read the Configuration File?

Whenever MX is restarted, it reads the latest Cumulus.ini and if it exists strings.ini (briefly mentioned below); from these one (or two) file(s), it learns the configuration that you want it to use.

Essentially, MX reads the whole file, for each attribute part of a parameter in the file, there is a variable stored within the MX code. So the value part of each parameter is assigned to the respective variable. Hence MX will not permit any duplicates for any parameter. If MX finds a parameter it does not understand, it ignores that parameter.

This means a Cumulus.ini file created by the legacy software, or by an old release of MX, can still be read by the current release of MX, as it just ignores all the obsolete parameters. However, since MX now has a lot of new parameters in the file, that were not in the legacy file, nor in a file created by an early MX release, it is often easier to start again with a new configuration file, as explained later, to ensure the configuration of MX is correct for you.

MX also creates a backup copy of "Cumulus.ini" in a sub-folder of Backup folder that is named according to current date and time.

What MX finds in your "Cumulus.ini" does of course determine what you see when you open any of the Settings pages, in the admin interface. This is because the displaying of some settings is dependent on another setting.

For completeness I mention here, configuration information for MX can also be stored in an optional file strings.ini, that is used to identify how various standard output phrases are to be modified to suit you.

Settings Configuration for MX

The MX software offers much functionality and flexibility. Consequently, it has an extensive set of configuration settings, fortunately apart from the initial settings of model and units (see next sub-section), recent releases have simplified many of the settings for optional features by providing particular selections to affect a whole range of others (for predicted uses), instead of forcing you to individually work through every individual setting.

First run of MX

This Wiki page does not explain how to start using MX, please see MX on Linux, MX on Windows OS, and MX Administrative Interface as appropriate.

The key fact relevant here is that no Cumulus release distribution contains a Cumulus.ini file. So when you first use the software, you will need to use the admin interface to enter all settings (some have defaults that might be right for you) as described later in this page, and that will lead to creation of the main configuration file.

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 admin 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,
   • The settings that are displayed to you vary depending on the station type you have selected (and the particular MX release), so there is not a screenshot to show you the other settings for your station type.
7. Optionally, move to other settings pages accessed from the menu seen in the image, these cover the optional functionality of MX, so the pages you need to visit depends on what functionality you wish to use.
8. Optionally, use Samplestring.ini file as a guide to 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.
   • The advantage of creating your strings.ini file now, is that it is read when MX starts, and we will shortly restart MX.
9. Closing MX is the action that will create the main configuration file.
10. MX must be stopped correctly, because it has to do a number of actions after it receives a request to close:
    • If you have a screen attached to the device running the MX engine, you can click in that screen and terminate Cumulus MX by typing C while holding down the control key (or equivalent if you are using an apple mac).
    • If you are connecting to MX from a remote device, then type into that remote session the control C.
    • Otherwise do whatever is needed to end the MX executable on your installation.
11. Restart Cumulus MX, it will read your new settings (in Cumulus.ini and the optional strings.ini) 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), but from now (until you stop it) it will read (and from time to time log) the live data while MX remains running.

What happens if I upgrade MX?

If you upgrade to a newer MX build, as that release distribution does not contain a "Cumulus.ini", you cannot lose your settings entered in your existing file. However, be aware that a new release may remove some settings, and add new settings, hopefully the release announcement will give specific details. Otherwise, you will need to work through all the Settings Pages, and all the "MX Sections" (see Terminolgy above)

Where do I change settings?

The current design of MX expects that Cumulus Users will never need to edit the "Cumulus.ini" file directly, as there are a number of settings pages in the admin interface and users are expected to use those Settings pages to amend the individual MX settings.

Please see MX_Administrative_Interface#Changing_Settings for basic information, including how to load the admin interface (sometimes called the "dashboard interface" or "user interface").

Furthermore, at the end of each (meteorological) day, MX creates a back-up in the backup/daily/TIME_NAME sub- folder. The TIME_NAME is constructed from a string of digits representing the date and time the directory was created (without any punctuation) e.g. 20060519090000. In that folder, recent MX releases, include a copy of the current "Cumulus.ini" file.

Do I need to restart MX?

If you change a setting directly in the file, you must stop MX beforehand. The setting takes effect when you restart MX.

If you change a setting, using the admin interface, it may, or may not, take effect immediately...

The settings available on the various pages in the admin interface fall into two groups:

1. SETTINGS THAT TAKE EFFECT IMMEDIATELY ON CLICKING “SAVE”
2. SETTINGS THAT ONLY TAKE EFFECT WHEN MX IS RESTARTED

There used to be a third group. Before Release 3.11.2 - build 3131 a few changes made in the interface were not saved into "Cumulus.ini", and those few settings were therefore lost when MX was restarted. One example of these former exceptions was that the former action selecting adding extra debugging information to file in MXDiags folder was previously not saved for subsequent session.

For the current MX release, any change made (on any settings page) will be saved into "Cumulus.ini", and will still apply when MX is restarted. That restart will ensure all settings changed in the last session do take effect, even those that did not take effect before the restart.

Unfortunately, there is no documentation available from developer on which settings, at any release, do not take effect until MX is restarted. We do know that you need to do a restart after choosing the station model, and that is unlikely to change.

In early MX releases most configuration settings required a restart of MX before they took effect, but since then in some releases, certain settings that used to require a restart have been changed so they take effect intermediately. It is anticipated, as MX develops, the majority of settings will become ones that take effect without a restart of MX.

This means that any attempt to document here which changes do require a restart of MX is working against a moving target. Consequently, this documentation does not indicate where a restart is required. You can either play safe, and restart MX each time you finish making edits to settings, or you can read all the support forum announcements, and see if you can find any information about whether a restart is needed, for whatever particular settings you are changing, at the release you are using.

How to Remove Redundant parameters from file

If you have been using Cumulus for a while, there might be parameters that are now obsolete left in your configuration file.

MX will ignore any parameters that it no longer recognises, but there is a simple way to make MX create a new file for you, keeping your existing settings, but ensuring the new file does not have any obsolete parameters.

The following procedure is best done after, not before, you upgrade MX, as installing a new release might add/remove parameters to/from "Cumulus.ini".

Apart from that upgrade consideration, you can start afresh with a new file anytime by following this very simple procedure:

You must do this while keeping Cumulus MX running (to preserve existing settings)...

1. Rename your existing Cumulus.ini to say Cumulus.ini.sav (this keeps the file, but stops MX finding it)
2. In Cumulus go to one of the settings screens, (e.g. Program Settings which is currently a short page) – simply click ‘’’Save Settings’’ (i.e. any action that makes MX save settings to its configuration file)
   • It is possible this might highlight a new parameter that does not yet have a valid value (e.g. the Alarm settings page, which uses ‘’’Enable Alarms’’’ rather than "Save settings", got extra settings without defaults at 3.11.0).
3. Cumulus (if it accepts that save) will now create a brand new Cumulus.ini file,
4. This will have all the settings you have chosen
5. They will now be in the order MX is expecting
   • MX default sort order is from where entries are set in the code, and that is far from alphabetic!
6. As MX is unaware of settings it used previously, but does not use now, (and MX is unaware of what settings the legacy software used), it won’t write back any redundant settings in the new configuration file.

As well as changing the order in which parameters are stored, this re-generation may show up other changes (if you do have reason to examine the new file and compare with the old file):

• A major change is likely in the '''[Station]''' section as that has seen a lot of changes as MX is developed.
• The ’’’[Graphs]]’’’ section has also seen a number of changes as MX has developed.
• The most dramatic change may happen in '''[FTP Site]''' as any reorganisations to the list of parameters for Extra Web Files are reproduced 100 times.

Editing the file directly

At the time of writing this, the work to code up MX settings pages is not yet completed.

So the Settings Pages could not modify all the parameters, that can appear in the file and get used by MX. Therefore, there were still some settings that could only be amended by stopping MX, then editing the relevant parameter in the file directly, before restarting MX.

However, it is likely that in a few releases time, there will be no necessity to directly edit the file.

That said, working through the various settings pages, and all the options (often within multiple MX sections) can be laborious. Consequently, those with some understanding of the file contents may still wish to make some changes with MX stopped, by editing the file. The only caution that needs to be stressed is "be careful"; as this editing the file directly bypasses any validation that is done when using the Settings Pages, and so might result in an inconsistent set of parameters, and (in the worse case) perhaps a software crash.

An example of why you might edit file instead of using Settings Page

If (for example) you find the Extra Web Files editor hard to use, you might decide to stop Cumulus MX and still edit this configuration file directly for changes to those parameters. Given that MX ignores any parameter it does not understand, while editing the file, you can temporary have old and new parameters in the file. All you need to do is prefix those parameters you don't want MX to use with any character you like before the "Extra" in the attribute name.

When MX adds new parameters to file

In theory, there is no reason why you should manually add any extra parameters directly into the file.

Since MX creates, and edits, the file, it should ensure all parameters it understands are in the file.

When this new page was being created, some of the parameters in the file that MX understands, could not be matched to any known setting in the Settings Interface pages, but it may be a future release will correct that.

If a new release of MX adds new parameters, then:

• If the new parameter has a valid default value, MX will work perfectly using that default value.
  • You won't need to know the parameter exists, unless you decide to change it, and find out what values it can take either in a drop-down on the relevant Settings page, or in the relevant table below.
• Other new parameters may be given an initial illegal value, because MX cannot guess what value will work for you.
  • This is to enforce the need to give these parameter a valid value before MX will allow you to save settings.
    • Sometimes, MX will not do any weather data processing, until these ‘’’missing’’’ values are edited.
    • In other cases, you might not realise that your file is missing one or more parameters, unless you go into the relevant Settings page, and find you can't save (Enable for Alarms page).

In practice, as already mentioned, there might be a parameter that you need to get MX working correctly for you, but have to add directly to the file as (at the release you are using) that setting has not yet been added to any Settings page.

Before this page actually lists all the settings I know of, let me give an example of a seting with a valid default, and an example of a setting that has an invalid default:

Example of new Parameter with valid default

When accessibility was added, its parameter defaulted to the old expand/contract sections design (see first table below).

You can, optionally, go into "Program Settings" or "Station Settings" pages, where you tick the box to get the (more accessibility friendly) selection button alternative.

Example of new Parameters with no valid initial value

As a specific example, release 3.11.0 added emailing capability; that requires quite a lot of new parameters to be added to the file. You could use MX without these new parameters, but the Alarm Settings page would not allow you to click Enable until you had defined various settings on another Settings page, as well as on this Alarm Settings page.

Tables listing Settings

Accessibility

• Introduced Release 3.10.0 - build 3115
• File Section is [Program]

Parameter Line Entry	MX Section	Label on Settings page	Default	Description

Leave it at zero for a Click ▶to expand, click ▼ to collapse styling.

Alarms (and emails)

In the table below "Notify" determines whether an alarm is shown on the "Dashboard" page, for release 3.11.2 and subsequent the alarm also has to be enabled for it to appear.

Introduction column:

1. There was no alarm functionality in builds in the 3.0.0 and 3.1.x series
2. Any alarm functionality where the column says "Legacy Cumulus" was available before 1.9.0 and introduced into MX in one of the releases between 3.2.0 and 3.5.4.
3. Any alarm functionality where the column says "Cumulus 2" was requested for that withdrawn flavour, subsequently added to a 1.9.x release, introduced into MX in one of the releases between 3.2.0 and 3.5.4.
4. New alarm functionality introduced in the range of releases 3.2.0 to 3.5.4 has that range shown (rather than the exact release).
5. For alarm functionality first introduced in or after release 3.7.0, the release of introduction is shown in "Introduced" column.
6. There were no changes to Alarm functionality between 3.7.1 and 3.8.4 inclusive, so if you are running one of the 3.8.x releases, the Wiki page that applies for "alarms" is the early MX releases page, not this Wiki page.
7. In the range of releases subsequent to 3.9.0 as covered by this Wiki page, the alarm functionality has been dramatically changing:
   • Latching of alarms was introduced at 3.9.1 (b. 3096), most alarms had no default for how long they stayed "latched", but at least one had a 12 hour default and at least one had an until end of day default.
   • At 3.9.2 (b.3097) reporting of notifications were added to the admin interface (called "Cumulus Dashboard" in the relevant release announcement at Cumulus MX Announcements and Download - PLEASE READ FIRST,
   • At 3.9.5 (b. 3100) the latching functionality was corected,
   • At 3.9.6 (b.3101) the alarm latch hours were all defaulted to 24 hours,
   • At 3.11.0 (build 3129) where the email functionality was added,
   • And at 3.11.2 (b. 3131) where the release announcement says "this release sees the Alarms getting some more love".

"Shown on Settings page?" and "MX Section" columns:

• For releases between 3.2.0 and 3.10.5, all alarm related settings were "always" shown, and none required opening a "MX section".
• For release 3.11.0 and subsequent releases, the introduction of email functionality means there are now some alarm related settings on the "Internet Settings" page, where there is a section "Email Server Settings" that needs to be opened, and a master setting that determines whether other settings are shown or not.

"Label on Settings page" column:

• For releases between 3.2.0 and 3.10.5, all alarm related settings were shown using a HTML table, so the entry in the label column in the table below quotes the text shown after the check box that starts the settings table row
• For release 3.11.0 and subsequent releases, the introduction of email functionality means there are now some alarm related settings where the label column quotes the text shown beside the individual setting, but all other alarm related settings quote the text shown after the check box that starts a settings table row

Request for help from Wiki Readers

• Do you understand how MX works?
• Do you use hardware, or MX functionality, that is not yet documented? Can you begin that documenting?
• Can you contribute simple text for novice users, examples of what you have done, correction of typing or factual errors, or supply missing details?
• Will you make this page more useful by bringing content up-to-date as new releases change some information written for older releases?
• Does any page need a section for novices, so they don't need to read more technical information further down that page?
• Is there some information on this page, that should be on a separate page? Can you create the new page and move the less relevant information off this page, don't forget this page needs a link to the new page so people who expect to find it here know where it has moved to?

If this date is edited, keep to same format. MX generally (see Calculate_Missing_Values#CreateMissing.exe for exceptions) ignores any data file entries prior to this date.
UseDataLogger=1	(probably determined by station type)	(not known)	(not known)	1 (enabled)	Simple tick or not Tick (value shown as 1 in Cumulus.ini) if your weather station has its own storage, so MX can do a catch up when it first starts and read any "archive data" Don't tick (value shown as 0 in Cumulus.ini) if your weather station has no storage, and therefore MX cannot capture any readings when it is not running
Use10amInSummer=1	(Always)	Station settings → Log Rollover	Use 10am in Summer	1 (normal)	Tick box: 0 = If "Daylight Saving Time" (DST) applies in Summer, If rollover time is midnight, then rolls over at midnight local time, regardless of whether DST is in operation or not If rollover time is 9 a.m., MX is to use 9 am local time, regardless of whether DST is in operation or not 1 = Normal behaviour: If rollover time is midnight, then rolls over at midnight local time, regardless of whether DST is in operation or not If MX would do an end of day process when the time (on Weather Station if it provides time) reaches 9 a.m. local standard/winter time, then it waits until 10 a.m. local time while DST is in effect

Display Options

• File Section is [Display]
• MX Section is Station Settings → Display Options

Parameter Line Entry	Introduced	Label on Settings page	Default	Description
DisplaySolarData=0	??? 3.10.0 ???	Display Solar data	Unticked (shown as 0 in Cumulus.ini)	Simple tick or not Tick (value shown as 1 in Cumulus.ini) if you want MX to display solar data in tables shown on the web pages provided in webfiles folder (from release 3.10.0 onwards) Don't tick (value shown as 0 in Cumulus.ini) if you want MX to suppress the table cells that would display solar data
DisplayUvData=0	??? 3.10.0 ???	Display UV-I data	Unticked (shown as 0 in Cumulus.ini)	Simple tick or not Tick (value shown as 1 in Cumulus.ini) if you want MX to display ultra-violet intensity data in tables shown on the web pages provided in webfiles folder (from release 3.10.0 onwards) Don't tick (value shown as 0 in Cumulus.ini) if you want MX to suppress the table cells that would display UV intensity data
NumWindRosePoints=16	Legacy Cumulus	Number of wind rose points	16	Drop-down determining if weather station bearing supplied by weather station is to be converted to 8 or 16 compass directions (i.e. whether to include or exclude (in English) NNE, ENE, ESE, SSE, SSW, WSW, WNW, and NNW 8 points 16 points Despite what it says in the hint on the settings page, leave at default whichever weather station type you use, unless this actually causes you a problem. The parameter was introduced by Steve Loft. Davis wind vanes use a potentiometer to measure wind direction so send Cumulus a bearing that can vary continuously between 1 and 360 degrees. Fine Offset wind vanes use magnetic switches that depend on the magnet under the moving part selecting two switches in the fixed part for the vane being exactly in-between compass directions, and selecting one switch for the main 8 directions and slightly away from the main directions; so they have a bias against sending Cumulus the in-between directions.
UseApparent=1	??? MX 3.6.0 or 3.10.0 ???	Use Apparent Temperature	Ticked (shown as 1 in Cumulus.ini)	Simple tick or not Tick (value shown as 1 in Cumulus.ini) if you want MX to display apparent temperature in tables shown on the web pages provided in webfiles folder (from release 3.10.0 onwards) for consistency with Cumulus prior to release 3.6.0 Don't tick (value shown as 0 in Cumulus.ini) if you want MX to display feels like temperature in tables shown on the web pages provided in webfiles folder (from release 3.10.0 onwards) for consistency with Cumulus from release 3.6.0

Extra Web Files

There are 100 occurrences of each parameter in Cumulus.ini, and therefore each parameter has a base name followed by numbers 0 to 99.

The settings interface presents the rows on multiple pages, the rows are not numbered, so you have to do some counting to work out which row in the admin interface page corresponds with which parameter in Cumulus.ini file.

You MUST restart MX after any changes in this section, before the new settings take effect.

Parameter Line Entry	Label on Settings page	Default	Description
[FTP site]			Section name
ExtraLocal0= to ExtraLocal99=	Local File Name	(empty)	You can enter: A relative path name, with respect to the "CumulusMX" root folder e.g. ./data/dayfile.txt (Note: this is the daily summary log file, see link for how it can be used on a web server) e.g. ./webMX/betel_monthlyrecord_liteMXT.html (Note: this is a third party template file - see Alternative Monthly Extremes using <#webtag>s e.g. ./web/trendsT.htm (Note: That file is not part of default web site any more, but serves as another example A full path name for a file on the computer running MX e.g. /home/pi/documents/myFile e.g. C:\Users\Public\Documents\working.txt You can place any of the following special tags into the entry These should be typed as shown on their own <noaayearfile> and <noaamonthfile> these respectively represent latest yearly and latest monthly reports <currentlogfile>, <currentextralogfile>, and <airlinklogfile> these respectively represent standard, extra sensor, and Davis AirLink air quality monitor log files e.g. ExtraLocal3=<currentlogfile>
ExtraRemote0= to ExtraRemote99=	Destination Filename	(empty)	Defines where MX is to upload file to If file transfer is requested (see below), the file path should be expressed starting at the FTP/FTPS/SFTP root I can't tell you what the file path is for your web server, but I can give a couple of examples to steer you e.g. httpdocs/dayfile.txt e.g. public_html/thismonthyear.htm If the FTP is not ticked, the file path should be full path for a file on the computer running MX e.g. /var/www/html/weather/images/moon.png could be destinatation for uploading the MX generated moon image to a Linux hosted server e.g. /var/www/html/weather/webfilesMX/tempdata.json for uploading one of the files with graph data to a Linux hosted server You can place any of the following special tags into the entry These should be typed as shown as part of the destination path, note that they can be used: either to represent the final filename part of the path e.g. ExtraRemote3=/var/www/html/weather/monthly/<currentlogfile> or to modify a filename, so it becomes unique to a particular month e.g. ExtraRemote0=/var/www/html/weather/cumulus_generated/savedFiles/web_tags_real_time_<currentlogfile>.inc <noaayearfile> and <noaamonthfile> these respectively represent latest yearly and latest monthly reports <currentlogfile>, <currentextralogfile>, and <airlinklogfile> these respectively represent standard, extra sensor, and Davis AirLink air quality monitor log files

Optional Web Server

The settings listed here changed dramatically at both 3.10.0 and 3.12.0 releases, but they have gradually evolved throughout the development of MX.

FRom 3.12.0, MX can optionally either copy files to a web server you host or file transfer files to a commercial web server.

To implement (and customise) this web server functionality, there are many settings as listed alphabetically in this table. The Internet settings page simplifies making settings by providing selections that amend multiple settings in a bulk operation:

• Some settings (marked ^ in table) are only displayed if you select I want to use the supplied default web site.
  • For these settings, the "Generate" option is enabled in nearly all (see any qualifier) settings
  • If you select "Enable file copy of standard files" (default is disabled) then those settings have their "Copy" option enabled in nearly all (see any qualifier) cases, and their "FTP Transfer" option deselected (instead of defaults shown in table)
  • If you deselect "Enable file transfer of standard files" (default is enabled) then those settings have their "Copy" option disabled, and their "FTP Transfer" option enabled in nearly all (see any qualifier) cases (as per defaults shown in table)
• The default selections assume you have air quality, and solar, sensors; so you may need to disable some of the defaults the above selections have made
• If you don't select I want to use the supplied default web site, then all the settings marked ^ are disabled
  • This is what you want if you do not use the MX optional web server functionality
  • If you have a customised web site, you may want to select I want to use the supplied default web site to see the settings that would otherwise all be disabled, and then pick any options that would be useful to you.

Program Start-up Options

• Introduced release 3.9.4 - b3099
• File Section is [Program]

Parameter Line Entry	MX Section	Label on Settings page	Default	Description
StartupPingHost=	Program Settings → Program Start-up Options	Host to PING on program start-up	None (no remote host)	Add a hostname or IP to address to ping at startup. Cumulus waits until the ping is successful before trying to read from your station. Leave blank to disable
StartupPingEscapeTime=999	Program Settings → Program Start-up Options	PING escape time (mins)	999 (minutes)	Specify a time after which if no ping response is received carry on starting Cumulus MX anyway
StartupDelaySecs=0	Program Settings → Program Start-up Options	Start-up Delay (secs)	zero (no delay)	Add a delay before the Cumulus tries to start reading the station.
StartupDelayMaxUptime=300	Program Settings → Program Start-up Options	Max system uptime to apply the start-up delay	300 (seconds equivalent to 5 minutes)	The time that has passed sice MX was started (up-time) is compared against the (max delay time) figure here. If max delay time less than up-time, the delay specified in previous parameter will NOT be applied If up-time less than this max delay time, then MX will apply any delay specified in previous parameter If this parameter is set to zero, then MX will always apply any delay specified in previous parameter

Proxy

This is a continuation of an experimental legacy Cumulus software feature, please see here for request and see here for potential content. I have not seen any evidence that this feature ever came out of beta, and nobody has ever commented on its use, so I see no reason to do any further documentation.

Station specific alternatives

A number of settings are shown only for specific station types, and so the following tables are grouped here.

Since MX is being developed by someone who uses a Davis station, a lot of "Labels on the Settings Screens" mention "Davis" even if you have selected a different station, because the code was written by copy and paste!

Solar

Cumulus MX is unable to work out if you have a solar sensor, so these options are always displayed.

Parameter Line Entry	File Section	Introduced	MX Section	Label on Settings page	Default	Description
SolarCalc=0	[Solar]	3.13	Station Settings → Solar	Solar Calculation Method	0=Ryan-Stololzenbach	Drop-down list: 0=Ryan-Stololzenbach 1=Bras
SunThreshold=75	[Solar]	3.13	Station Settings → Solar	Sun Threshold (percent)	75	Enter a number
SolarMinimum=0	[Solar]	3.13	Station Settings → Solar	Solar minimum (W/m2)	30	Enter a number

• Introduced for legacy Cumulus
• File Section is [Station]
• Only "Shown on Settings page" if either "Type=0" or "Type=1"

Parameter Line Entry	Label on Settings page	Default	Description
[Station]			Section name - the following parameters appear in Station section
VP2SleepInterval=500		500 (milli-seconds)	the period which Cumulus waits between reads of the data from Davis stations, the value is in milliseconds. if you suspect that data is being missed, reduce number For VirtualVP users, tests revealed that VP2SleepInterval = 1100 seems to work the best. It updates every two seconds with few exceptions.
VPClosedownTime=x		(default not yet documented)	x is the number of seconds after the start of the re-connect attempts that you want the program to close itself
DavisCalcAltPress=1		1	Davis stations calculate Sea Level Pressure (SLP) from Station Pressure (SP) using a formula based on temperature, humidity, and altitude CWOP require 'Altimeter Pressure' (AP) to be uploaded, i.e. a value calculated simply using altitude. 0 = Use SLP supplied by Davis 1 = Convert the SP Davis supplies to AP using the altitude you have supplied.
SyncDavisClock=0		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		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		2222	Communications port used if VP type has TCP/IP selected.
VP2IPAddr=0.0.0.0		0.0.0.0	Weather station IP address if VP type has TCP/IP selected.
VP2PeriodicDisconnectInterval=0		0 (disable)	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		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		1 (use Loop2)	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		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, see Cumulus MX forum where times up to 2000ms are suggested.
ForceVPBarUpdate=0		0 (normal)	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		1	(from version 3.0.0 build 3042) 0= Pressure values shown to 1 decimal places when reported in mb/hPa, shown to 2 decimal places for inHg 1= Pressure values shown to 2 decimal places when reported in mb/hPa, shown to 3 decimal places for inHg
VPrainGaugeType=0		1	Specifies the units selected on your Vantage Pro Rain Gauge. 0 = Metric Rain Adapter fitted, a 0.2mm gauge 1 = Imperial gauge without adapter, a 0.01" gauge. Note that if the units you choose for rainfall do not match your rain gauge type, conversion rounding errors will then occur.
DataLogging=0		0	(Build 3018 onwards). 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		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		(default not known)	set this on station settings screen; to enable/disable the entry/update of the stations IP address via auto-discovery

This table has not been populated yet

• Introduced in a MX beta build
• File Section is [WLL]
• Only "Shown on Settings page" if "Type=11"

Parameter Line Entry	Label on Settings page	Default	Description
[Station]			Section name - the following parameters appear in Station section

EasyWeather (Reading File instead of connecting to a Weather Station)

This sub-section is based on what applied for the legacy software, assuming nothing has changed for MX.

• Introduced in a Legacy version
• File Section is [Station]
• MX Section is "EasyWeather File Settings"
• Only "Shown on Settings page" if "Type=4"

Parameter Line Entry	Label on Settings page	Default	Description
EWInterval=10	File Read Interval	10 (minutes between new line becoming available in file)	Cumulus needs to know how often to read a new record from the easyweather.dat file. Enter any number in box. 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
EWFile=	Filename	(empty)	* Full file path/name for Easyweather.dat or EasyWeatherPlus.dat (empty) (i.e. attribute and equals sign, but no value) 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 See FAQ here for reduced functionality using Cumulus 1 in this way.
EWminpressureMB=900	Minimum Pressure Value	900	Cumulus will ignore all pressure readings from the station that are less than this value (units are always hPa/millibars)
EWmaxpressureMB=1200	Maximum Pressure Value	1200	Cumulus will ignore all pressure readings from the station that are greater than this value (units are always hPa/millibars)
EWMaxRainTipDiff=40	Rain Tip Difference	Default=30 tips in Cumulus 1, MX default is 40 tips	This configurable threshold is 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 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>.
EWpressureoffset=x.y	Pressure Offset	9999	The pressure that Cumulus MX processes is equal to what read in the file plus the value set for this parameter. Normally used to convert the station pressure to the equivalent Sea Level Pressure.

An Ecowitt user needs to check/update this sub-section, it is understood significant changes are included in 3.12.0 beta builds, but the forum does not give away any details

• Introduced in release 3.2.0
• File Section is [GW100]
• MX Section is "Ecowitt GW1000 Settings"
• Only "Shown on Settings page" if "Type=12"

Parameter Line Entry	Label on Settings page	Default	Description

Fine Offset Stations

• Introduced in a Legacy version
• File Section is [Station]
• MX Section is "Fine Offset Settings"
• Only "Shown on Settings page" if either "Type=5" or "Type=7"

Parameter Line Entry	Introduced	Shown on Settings page?	MX Section	Label on Settings page	Default	Description
FOReadAvoidPeriod=3	MX release ??	Only if Fine Offset selected	Station Settings → Fine Offset Advanced Settings	Read Avoid Period	3 (seconds)	If previous setting enabled, MX will avoid reading the circular memory from the number of seconds specified before it expects Fine Offset to be writing to the circular memory, to the number of seconds specified after it expects Fine Offset to be writing to the circular memory (One issue is that Fine Offset will move from one position to the next position in the circular memory, at the Fine Offset Logging Interval, but will delay this move by up to one minute, if the existing memory position is actually being updated by a read from the sensors and normally those updates happen every 40 seconds for non-solar sensors, and every 60 seconds for solar sensor)
??	MX release ??	Only if Fine Offset selected	Station Settings → Fine Offset Advanced Settings	Set the Fine Offset Logger interval to match Cumulus MX interval	0 (disabled)	Simple tick or not - labelled as "Experimental - use with caution" Tick (value shown as 1 in Cumulus.ini) for MX to attempt to "update the Davis interval" (I said copy and paste was used from Davis section!) to match the interval MX is using. Don't tick (value shown as 0 in Cumulus.ini) for no effect on your weather station
FineOffsetReadTime=150	MX release ??	Only if Fine Offset selected	Station Settings → Fine Offset Advanced Settings	Request/Read Delay	150 (milliseconds)	Adjust time (in milliseconds) between request for read, and actual attempt to read data via USB
ProductID=-1	MX release ??	Only if Fine Offset selected	Station Settings → Fine Offset Advanced Settings	USB Product Id (PID)	-1 (default setting)	Advanced setting if you don't want to leave it to MX to find your HID
SyncFOReads=0	Legacy Cumulus	Only if Fine Offset selected	Station Settings → Fine Offset Settings	Synchronise Reads	0 (disabled)	Simple tick or not Tick (value shown as 1 in Cumulus.ini) for MX to attempt to work out when your Fine Offset is writing data to the console log, so that MX does not read the Fine Offset circular memory when it is being updated Don't tick (value shown as 0 in Cumulus.ini) for MX to read the Fine Offset circular memory whenever it next wants data The parameter was added for legacy releases, to try to reduce the occurrence of "lock-up" issues. MX uses a different way to interrogate Fine Offset stations, originally ticking this could result in more reads being skipped, than actually processed, potentially updating just a few times a day, so it was best disabled! The MX code relating to this parameter was rewritten 1n 3.11.0, but the developer labels this as an "attempt", so it may still be best to try to manage without enabling this setting
VendorID=-1	MX release ??	Only if Fine Offset selected	Station Settings → Fine Offset Advanced Settings	USB Vendor Id (PID)	-1 (default setting)	Advanced setting if you don't want to leave it to MX to find your HID

The following table has some gaps to fill in, needs a contributor who uses this type of weather station

• Introduced in a Legacy version
• File Section is [Station]
• MX Section is "Instromet Settings" or "Instromet Advanced Options" as indicated
• Only "Shown on Settings page" if either "Type=5" or "Type=7"

Parameter Line Entry	MX Section	Label on Settings page	Default	Description
ComportName=xxxxxx	Station Settings → Instromet Settings	Serial port name	/dev/ttyUSB0 (on Linux), COM1 (on Microsoft Windows)	Only required if your station is connected via a real, or virtual, serial port
ImetBaudRate=19200	Station Settings → Instromet Settings	Serial Baud Rate (DavisBaudRate)	19200	Some ?older? Instromet loggers operate at 115200, if you have one of these older loggers you will need to reset this value
"SyncDavisClock=0" and "ClockSettingHour=4"	Station Settings → Instromet Advanced Options	"Sychronise Station Clock" and "Clock sync hour"	Tick box not selected, data box set to 4	Note despite the name of the parameter within 'Cumulus.ini', this does apply to Instromet stations. Simple tick or not Tick (value shown as 1 in Cumulus.ini) for MX to attempt to sychronise the Instromet Station Clock with your computer time. This ensures that when Cumulus asks the station for data since time X, both recognise X as representing same time! Don't tick (value shown as 0 in Cumulus.ini) if you don't want MX to attempt to keep station clock in line with computer clock Box taking an integer The hour of the day when, if enabled, Cumulus will set the Instromet clock to within a minute of the same time as the computer. This will happen at a default time of 04:00 each day, (4 a.m.) unless the setting box is edited
ImetUpdateLogPointer=1	Station Settings → Instromet Advanced Options	Update logger pointer	1 (enabled)	Simple tick or not Tick (value shown as 1 in Cumulus.ini) for MX to update the memory pointer to the last record after every 30 data reads Don't tick to disable this action
ImetWaitTime=500	Station Settings → Instromet Advanced Options	Delay between sending data read commands	500	Specifies the time in milliseconds that Cumulus waits after one read, before it does the next read from an Instromet station. According to the specification, 500 ms is the absolute maximum time that the station should take to respond to any command. For Cumulus 1, the default was 200 milli-seconds, so you might try that too.
ImetReadDelay=500	Station Settings → Instromet Advanced Options	Delay after sending a command before trying to read data from the serial port	500	Specifies the time in milliseconds that Cumulus allows after sending a command before it tries to read data on the serial port. According to the specification, 500 ms is the absolute maximum time that the station should take to respond to any command. For Cumulus 1, the default was 200 milli-seconds, so you might try that too.

The following table has some gaps to fill in, needs a contributor who uses this type of weather station

Parameter Line Entry	Shown on Settings page?	File Section	Introduced	MX Section	Label on Settings page (mostly in Alarm column)	Default	Description
LCMaxWind=X	Shown only if La Crosse was selected as station type	[Station]	3.12.0	Depends on release: (Version 1.8.8 Build 874 to release 3.11.4) Need to edit manually in file directly (Release 3.12.0 onwards) Station Settings → Common Options → Advanced Options	La Crosse max wind speed	???	It is setting for the La Crosse max wind speed, where X is the maximum (before calibrated by any definitions in Offsets) 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

It is assumed that most parameters remain same

Oregon Scientific WM918/WMR928 Settings

The Oregon Scientific code has not changed since the earliest beta MX (3.0.0) builds based on moving compiled code from Cumulus 1.

It appears very few current Cumulus users own these obsolete models, so all these settings have to be added directly into the file, you can't edit them in the admin interface, and they will be missing from any configuration file created by any MX release.

• Introduced for legacy Cumulus, and unchanged by MX
• File Section is [Station], these settings need to be manually entered into file below that section heading

Parameter Line Entry	External to MX edit	Default	Description
[Station]			Section name - the following parameters appear in Station section
Humidity98Fix=0	Stop MX and add this into file	0 (disable)	Applies to weather station types that never report more than 98% relative humidity. 0 = Disabled (default) 1 = Enabled, humidity displayed and recorded as 100% if your sensor registers a relative humidity of 98%. Normally only useful for Oregon Scientific stations.
LogExtraSensors=0	Stop MX and add this into file	0 (disable)	This setting determines whether MX looks for readings from extra temperature probes etc. 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..
WMR928TempChannel=N	Stop MX and add this into file	(by default no extra sensors)	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	Stop MX and add this into file	(by default no extra sensors)	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

• Edit on Station Settings page (except where indicated in bold as another page)

Parameter Line Entry	Introduced	MX Section	Label on Settings page	Default	Description
AirQualityDecimals=1	Release 3.9.2	Units → Advanced Options (Here be dragons!)	Air Quality decimals	1 (displayed as blank)	Number of decimal places for all outputs
AvgBearingMinutes=10	Legacy Cumulus	Common Options → Advanced Options (Here be dragons!)	Average Bearing Minutes	10 (minutes)	This parameter's value 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
AvgSpeedMinutes=10	Legacy Cumulus	Common Options → Advanced Options (Here be dragons!)	Average Speed Minutes	10 (minutes)	This parameter's value is the number of minutes over which Cumulus averages out reported current wind speeds
CalculatedDP=0	Legacy Cumulus	Common Options	Calculate dew point	Unticked (shown as 0 in Cumulus.ini)	Simple tick or not: Tick (value shown as 1 in Cumulus.ini) then Cumulus will calculate dew point from temperature and humidity supplied by station Don't tick (value shown as 0 in Cumulus.ini) action depends on Calibration settings If Cumulus has non-default multiplier and/or offset settings for temperature or humidity, Cumulus will calculate dew-point. This avoids the restriction in the Oregon Scientific stations where the dew point can never be below freezing point. If station provides dew point, then that will be used provided no multiplier/offsets have been specified for temperature or humidity
CalculatedWC=1	Legacy Cumulus	Common Options	Calculate wind chill	Unticked (shown as 0 in Cumulus.ini)	Simple tick or not: Tick (value shown as 1 in Cumulus.ini) then Cumulus will calculate wind chill from temperature and wind speed Note that there is a maximum temperature, and minimum wind speed, for Cumulus to make the calculation, see Wind_chill page Don't tick (value shown as 0 in Cumulus.ini) action depends on Calibration settings If Cumulus has non-default multiplier and/or offset settings for temperature or wind speed, Cumulus will calculate wind chill If station provides wind chill, then that will be used provided no multiplier/offsets have been specified for temperature or wind speed Note that some stations (Fine Offset, for example), do not make a wind chill value available to Cumulus. For these, Cumulus always calculates it.
ChillHourSeasonStart=	Legacy Cumulus	Chill Hours	Chill Season Starts	Default depends on release (up to 3.11.4) 10 = October (from 3.12.0) 4 in Southern hemisphere, 10 in Northern hemisphere	The value to enter is the month number (1=January, 12=December) and the Cumulative Chill Hours Count is reset to zero on the first of the selected month
ChillHourThreshold=	Legacy Cumulus	Chill Hours	Chill Hours	Default depends on Temperature Units Either 45 degrees Fahrenheit (equivalent to 7.22 oCelsius) Or 7 degrees Celsius (equivalent to 44.6 oFahrenheit)	Chill Hours are incremented by the number of (fractional) hours that the air temperature is below the threshold. In practice, Cumulus simply detects if the current temperature is below the threshold and adds an increment equivalent to the (interval) time passed since the last temperature reading. You can put in any value you want, with a decimal place if required Some people have put in the freezing-point temperature (0oC or 32 oF) and they relabel "chill hours" to "frost hours"

RainDayThreshold=	Legacy Cumulus	Common Options → Advanced Options	Rain day threshold	Default is -1 which depends on Rainfall Units AND station type -1 = normally 0.2 if units are millimetres -1 = normally 0.01 if units are inches Otherwise enter a value in your selected units	For derivatives like count of consecutive wet/dry days, any daily rainfall less than this threshold will be ignored. (If rainfall is measured in tips, usually set to just over one tip, as first tip of day might be result of less that one tip accumulated on earlier days or because of dew)
RainDecimals=1	Release 3.9.2	Units → Advanced Options (Here be dragons!)	Rainfall decimals	Default depends on Rainfall Units (displayed as blank) default is 1 if units are millimetres default is 2 if units are inches	Number of decimal places for all outputs
RainSeasonStart=1	Legacy Cumulus	Annual Rainfall	Start of rainfall season	1 (Jan)	Drop-down 1 = January 2 = February 3 = March ... 9 = September 10 = October 11 = November 12 = December Added in late 2010 because Cumulus users in Israel said they do not total rainfall from January. It was welcomed by people outside Israel, it turned out growers are often interested in a growing season rainfall total
RainUnit=0	Legacy Cumulus	Units	Rain	0 (mm)	Drop-down: 0 = millimetres 1 = inches
RoundWindSpeed=0	Legacy Cumulus	Common Options	Rounding of wind speed	0 (no)	Simple tick or not: Tick (value shown as 1 in Cumulus.ini) then MX will round all the wind speeds it reports to nearest integer Don't tick (value shown as 0 in Cumulus.ini) then MX will report wind speeds to the precision defined in "WindSpeedDecimals" parameter

UseCumulusPresstrendstr=0	Legacy Cumulus	Common Options	Cumulus pressure trend names	0 (depends on weather station type)	Simple tick or not: Tick (value shown as 1 in Cumulus.ini) then MX 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, but can be modified using strings.ini. Don't tick (value shown as 0 in Cumulus.ini) then effect depends on whether your weather station supplies pressure trends If your station does supply pressure trends, then MX will use those If your station does not supply pressure trends, then MX 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, but can be modified using strings.ini.
UseSpeedForAvgCalc=0	Legacy Cumulus	Common Options	Use speed for average calculation	0 (disable)	Simple tick or not: Tick (value shown as 1 in Cumulus.ini) then MX will use what the weather station supplies as "wind speed" to calculate the average wind speed.

If your rain season starts in January (default) then set this to the calendar year when you first use Cumulus (in a particular location). If your rain year starts in any other month, set this to this year if your first season starts this year, and set this to last year if your second season has started and you don't want the previous value added to your second season From Release 3.12.0 (?? July 2021), the current calendar year is compared against (current month - season start month + 1) year, so you enter the year in which your first season starts (be that last calendar year or this calendar year)
