  If omitted the parameter defaults to the first (or only camera) found on your account

    • There is one strings file per language
  • The settings strings are in /locales/dashboard/json/{language}
    • There is a folder per language, and a language strings files for each settings file

Changed

• All dashboard and default web site graph data files now use true UTC time stamps

  • Previously they were "pseudo-UTC" to force the graphs to display the station times rather the viewers time zone

  • Highcharts version used by the dashboard and default web site updated to v12.3.0 to support this

  • The charts will now render correctly at DST changes

  • IMPORTANT: You must upload the latest versions of the default web site pages and scripts files to support this change

  • IMPORTANT: If you have your own versions of Highcharts scripts, then the relevant change is from:

     {
     	time: {
     		useUTC: true
     	}
     }

    To (substituting your stations time zone):

     {
     	time: {
     		timezone: 'Europe/London'
     	}
     }

  • You must also use a version of Highcharts later than v11.2.0 - Cumulus MX now uses v12.3.0

• There is a new option in Station Settings > General Settings > Location to manually change the time zone used in the charts
• Added Davis Cloud API UUID option to the Configuration Wizard
• Add a retry to downloading Ecowitt SD card files on error or if returned file is empty
• The FTP log files have changed naming convention (to work better with the new version of NLog)
  • The latest file (if more than one), will be one with the highest value for NN for today: ftp-<logtype>_YYYY-MM-DD_NN.log
  • You will need to manually delete any old log files that use the old naming convention of:
    ftp-realtime-N.log or ftp-interval-N.log
• CreateMissing updated to v2.1.0 to fix the daily rainfall calculation on rain counter reset at rollover, and add support for evapotranspiration calculation
• Improvements in the Cumulus MX shutdown process - it should now be much faster
• The JSON and Tempest stations now use the same Sea Level Pressure calculation as all other stations
• All logging to log files is now asynchronous. This means a change to log file naming scheme for the main MX diagnostics
  • The latest log file will always have filename: MxDiags.log
  • Archiving:
    • Archived files will have the date/time appended: MxDiags-YYMMDD-HHMMSS.log eg. MxDiags-250726-115412.log
    • Archiving occurs when log files have exceeded 12MB in size
    • Archiving also occurs when you start Cumulus MX, the existing MxDiags.log will be renamed to a timestamped filename
    • The timestamp on archived files is the time of the last entry in the file, not the first
  • The maximum log file size has been decreased to 12MB, but the number of archives retained increased to 20
  • You may notice the logged event times only increment every 16ms, this is an efficiency thing!
• Logging of JSON responses from the Ecowitt Local HTTP API now compacts the output by removing line feeds and tabs from the text
