I perhaps should have explained my testing process so far. I have done exactly as you suggested already.  The data I posted above is the raw data as coming from WeatherDuino to Weewx. I am manually tipping the bucket to create rain and Weewx shows the rain amount in dayRain (used as part of the live data via MQTT) and the rain rate is recorded (see below) but not the actual rain amount. Yes I have the correct collector types etc.

I'll collect more data while I create rain and post that here.

Everything is still on my work bench for now
