The new value was much lower, but still very high. So I looked into the database and found that:
sqlite> select dateTime,rain,rainrate from archive where dateTime>1610960000 and dateTime<1610964000; 1610960100|0.0|0.0 1610960400|0.0|0.0 1610960700|0.0|0.0 1610961000|0.0|0.0 1610961300|0.0|0.0 1610961600|0.0|0.0 1610961900|0.015748031496063|5.79576771653542 1610962200|0.0|0.0666010498687663 1610962500|0.0|0.0385498687664041 1610962800|0.0|0.0131233595800525 1610963100|0.0|0.0 1610963400|0.0|0.0 1610963700|0.0|0.0 sqlite> As I did not find the word 'rainrate' within the driver file weatherlinkliveudp.py I guess that the rainrate value is calculated by weewx. I still wonder what causes those high values. Karen K schrieb am Mittwoch, 20.
