<big>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.</big>
{{Template:WorkInProgressBanner}}
=Purpose of Cumulus.ini file=
This is a text file containing initialization parameters. {{Template:Version badge Mx}}This page covers those used by the Cumulus MX software
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".
* 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"?=
[[Category:Configuration Files]]
# 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, <big>the decision was taken to abandon maintaining the page previously called "Cumulus.ini", and start again with a brand new empty page!</big>
All the pages, previously called "Cumulus.ini", can be found from the owning [[:Category:Configuration Files|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.
You will also note that this page does not cover all settings in detail, and find some links to further pages within some sections below
==Need to install MX 3.12.0 ==
If you are using Cumulus 1 or a release of MX earlier than 3.12.0, be aware that the content of "Cumulus.ini" is totally different to the file for later MX releases. (It might have been better had the file been given a new name in release 3.12.0).
The way the developer decided to implement it, is that when somebody installs release 3.12.0, any existing "Cumulus.ini" file is renamed, and a new "Cumulus.ini" file is created from scratch, and from then onwards all changes apply to the new file. As 3.12.0 is the only release that can create the replacement file, it is highly recommended that anybody currently using an older release, downloads 3.12.0 from [https://github.com/cumulusmx/CumulusMX/releases/download/b3141/CumulusMXDist3141.zip here] and runs that release for a while before upgrading to the latest release [https://github.com/cumulusmx/CumulusMX here].
== Simplifications ==
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:
# There could be more than one "cumulus.ini" file for the Legacy Cumulus up to 1.9.4, as explained [[Cumulus.ini_(Cumulus_1)#Configuration_File_names|here]].
# 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
#* 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!)
Whenever MX is restarted, it reads the latest ''Cumulus.ini'' and if it exists [[Strings.ini|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.
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.
<big>Please see [[First Run of MX]] for how to set up settings when you first use MX.</big>
==What happens if I upgrade MX?==
==Where do I change 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 folder|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?==
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.

== Alarms (and
The Alarm settings seem to frequently be changed by new MX releases, so have been moved to a separate [[Alarms|wiki page]] where hopefully it will be easier for somebody to keep the content updated in future.

==Optional Structured Query Language Settings==
MX uses a software package called "MySqlConnect" to run SQL queries.
Since the text that appeared here was added, documenting plans for the future 3.12.0 release, there have been a number of changes, and now a future release (3.20.0) is expected to make more drastic changes. Therefore the content has been moved to a [[MySqlConnect|new "MySqlConnect" page]] where it is hoped somebody will find it easier to update the content as MX develops.
==Optional Third-party Upload Settings==
==Optional Web Server==
There are two sub-sections below, because the settings for the optional web functionality are split between '''Station Settings''' and '''Internet Settings'''.
=== Display Options controlling what appears on default web pages ===

* 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.

=== File transfer and Copy Options controlling transfer of data to default web pages ===
The settings listed in table below changed dramatically at both 3.10.0 and 3.12.0 releases, but they have gradually evolved throughout the development of MX.
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

==Proxy==
This is a continuation of an experimental legacy Cumulus software feature, please see [https://cumulus.hosiene.co.uk/viewtopic.php?f=4&t=728 here for request] and see [[Cumulus.ini_(Cumulus_1)#Proxies|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==
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.

* 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

| 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

===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

* 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
** If Cumulus has non-default multiplier and/or offset settings for temperature or wind speed, Cumulus will calculate wind chill
** If station does NOT make a wind chill value available to Cumulus, Cumulus MX reports an error if you have not ticked this setting, (that is different to how the setting worked with the legacy software).
** If station provides wind chill, then that value will be used provided no multiplier/offsets have been specified for temperature or wind speed.

| 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.
| Rounding of wind speed
| 0 (no)
| Simple tick or not, (only applicable if any reported wind speed would otherwise include decimal places):
* Tick (value shown as 1 in Cumulus.ini) then

| Select a number of decimal places to overwrite the default. (NOTE: If the weather station does not provide an average wind speed, or if the user requires a change of units from how the weather station reports it, then CMX will calculate it to 1 decimal place by default; otherwise average wind speed will default to integer, or to one decimal place, depending how it is provided by the station).

| Wind speed average decimals
|
| Select a number of decimal places to overwrite the default which depends both on the weather station type and what units have been selected by user (speeds are normally reported as integers unless metres per second are reporting unit, because most sensors are not precise enough to give any decimal places in other units)
