Which rain figure are you comparing? Cumulus has lots of them - rate, daily, monthly, etc etc.

I hadn't noticed that. That may well account for the difference.

Cumulus calculates the daily rain by taking a snapshot of the station's 'total rain counter' at midnight, and then comparing the latest value with that during the day. You can see the figures that are used for the calculation by looking in the monthly log file. The midnight value is saved in today.ini as the Start= value.

It is not a problem, but I meant that it is not possible to compare daily rain on the WH1080 panel or easywheather with daily rain in Cumulus,
because all values in my WH1080 and Easywheather is calulated for last 24 hours or last 60 minutes etc. but Cumulus use (in my case) midnight to midnight
and values is of course not possible to compare.
And thankyou Steve, Cumulus is fantastic, I have used Cumulus for about 14 months, and almost no problems at all !! :D
