To compare: https://kainzbauer.net/weather/Rif/en/stats.html The linked page lists rain and piezo rain per day/month/year My WS90 is vanilla, I did not tune any settings. While a bucket is agnostic to the type of rain, the piezo sensor isn't. Large drops vs. mist make a difference. After a longer period of time the sums of the different sensors aren't that much away from each other. I don't give much about the sum the piezo sensor is reporting, but it delivers information when there is only a little rain or very light rain, which sometimes the bucket doesn't recognize at all.
