Displaying data in local time means that when changing between winter and summer time, either one hour is skipped on the axis or two real hours are displayed in a single hour.
The precipitation sensor Kalyx-RG functions according to the principle of the tipping bucket. One impulse corresponds to 0,216 mm of precipitation for me.
The sensor is not heated, so snow accumulates in the funnel and is only counted when it defrosts if it does not overflow.
The values before 1 October 2021 come from the ASTA weather station in Roeser, afterwards from mine in Crauthem.
