Yep seeing the same thing. Soil moisture is zero even on an all day drizzle, and a rain delay was not triggered. You can manually increase the soil moisture for each zone but I am not sure that actually helps. I also have a wunderground weather station, and cannot select it was a PWS. As a feature request it would be nice to be able to enter the amount of rainfall a local rain gauge records when we add a manual rain delay. In my case the rain fall at the local airports is useless since its almost 600ft closer to sea level.
