1. The UI is so confusing that even after having it for 5 months I still can't figure out why the designers have so many options to do so few things. 2. But worse, the one main thing I really bought this for was to more easily schedule sprinklers. WHICH DOES NOT WORK. My sprinklers now run at what seems to be random times of the day. They definitely do NOT run when I have scheduled them to. And there is no clock in the app to know what time the app thinks it is.
