Monthly log files
Files are automatically created with names in the form <Month><Year>log.txt (for example, the file for August 2009 is called Aug09log.txt); an entry is made to the current month's file every ten minutes (default value; you can change this on the station settings screen), recording the current sensor values. The file is in comma-separated format with one line per entry.
Important: The date format uses two digits for the year. Do not edit this file using Excel or similar, as it is likely to change the dates to have four figure years, and then Cumulus will no longer be able to use the file.
Format of the file
- Date in the form dd/mm/yy
- Current time
- Current temperature
- Current humidity
- Current dewpoint
- Current wind speed
- Current wind gust
- Current wind bearing
- Current rainfall rate
- Total rainfall today so far
- Current sea level pressure
- Total rainfall counter
- Inside temperature
- Inside humidity
- Current gust (i.e. 'Latest')
- Wind chill
- Heat Index
- UV Index
- Solar Radiation
- Evapotranspiration
- Annual Evapotranspiration
- Apparent temperature
- Current theoretical max solar radiation
- Hours of sunshine so far today
- Current Wind bearing (used by Cumulus for graph drawing after a restart)
Times in these files are in the form hh:mm using the 24 hour clock and local time (system time). Note that the fields related to solar data will only contain valid data if your station has the appropriate sensor(s).
Example of the file
Filename: sept10log.txt
Note that your field delimiters may be different, and your date delimiter too. Here the field delimiter is a semicolon ,the decimal separator is a comma, and the date separator a dash.
