Rich, no success :( I've changed like you suggested, "rain" field and "contains_total = True". Now it started to rain again and my bucket is reporting 8.0 (was 2.1 before rain start), but weewx is reporting 51mm/h! I'm really lost now.
One thing I'm sure: my sensor has been reporting total rain since it started.....it's not resetting (at least not until 24h).
