We solved this issue by putting our zip code in the settings. If it doesn’t have a zip code, it doesn’t know where it is, and the smart watering (which is not really that smart) won’t work.
The most annoying thing about smart watering is that it will try to delay watering if there is a wind advisory. We have drip irrigation and are on a windy hillside so we are constantly disabling the irrigation delay.
Hope this helps you!
