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 you plan on CONTRIBUTING to the Wiki, then you will need a userid.

When everyone used Cumulus 1, the Cumulus Wiki was highly rated as being comprehensive. But the legacy software was much simpler to document, and there were multiple contributors, one of whom was the Cumulus author who knew what the software was doing. (Unfortunately, it is not easy to convert pages originally written for the legacy software into pages that document MX, as it is often unclear if the two flavours work the same way, and MX is diverging rapidly from the old functionality).

Please be aware that any information on this page may be incorrect, unless the relevant contributor was the developer. This is because when new releases change functionality, the announcement is often unclear on what exactly changed. A lot of research is often needed before MX can be correctly documented here by any other contributor!

  • This sub-category provides links to pages that give explanations for all of the Log files with a .ini extension within Cumulus.
  • It applies to both the legacy 1.9.4 and the latest MX release, as both flavours use files with same names, although there are some differences with their content.
  • Descriptions, and tips, can be found in the Help file within the Cumulus 1 software, it can be read at Cumulus.chm although it is formatted to only open if your computer is using a Microsoft Windows Operating System.

The file types used by Cumulus

Essentially, there are 2 file types used by all flavours of Cumulus:

  1. .ini file type - these hold values that represent sums, counts, or extremes, for cumulus to read, and update, as it reads the weather observations, click on links below for details.
  2. .txt file type - these are the logs that Cumulus updates at defined intervals to hold details of what has happened, but it can also read these files when requested, please see .txt files category for details.

Badge v1.png The following types were used by Cumulus 1:

  1. .rec file type - this has been deprecated, and replaced by .ini, for details see Alltime.ini.
  2. .xml file type - this holds the Cumulus 1 Weather_Diary. Although it uses standard XML, the component that Cumulus 1 uses also writes a special value that other XML editors will not understand.

Badge vMx.png The following types are only used by MX:

  1. .db file type - there are two of these for Cumulus MX, click on Diary.db or Cumulusmx.db for details.
  2. .json file type - these hold data to be sent to a web server, please see .json files category for details. See MX announcements for more details, as this functionality varies depending on your MX release.

General points on all these .ini files

The format in each .ini file consists of a number of sections (section title is delimited by square brackets [...]).

In each section you will find a number of properties (consisting of attribute name, an equals sign and a value) each on a separate line.

Blank lines can be added anywhere for readability, they are ignored in these Cumulus .ini type files.

File content differences between Cumulus 1 and MX

Badge vMx.pngDecimal formatting always uses a period/full stop in Cumulus MX. Cumulus MX shows date/time in ISO 8601 format of "yyyy-MM-ddTHH:mm:ss" (using the net specifiers that MX uses).

Badge v1.pngDate, Time and Decimal formatting is as per your regional settings on the PC running Cumulus.

Thus if you want to swap from Cumulus 1 to Cumulus MX, and you previously used a comma as your decimal separator (e.g.12,3) you will copy your existing Cumulus 1 "data" folder to within your MX installation, but you then need to manually edit every XXXXXXX.ini file so all the values entries are converted to use a full stop as decimal separator.
