I’ve had much the same problems as @freedom561 but with freeze skip added in - and all my zones are on Flex Daily. I’ve seen many instances this winter of watering just hours before predicted rain began and freeze skips applied when my personal weather station (KCAPASOR299) shows an air temp over 32° or no freeze skip when the temp was 30°.
I cannot figure out where the forecasts come from as they do not match the Weather Underground or NWS forecasts.
It’s just not consistent
