Regarding Time, I’ve setup watering to occur every 2 days. The iOS App reports watering will occur, for example Tuesday 07:00. It does not water Tuesday 07:00. Instead it waters the following day, Wednesday, at 07:00. The iOS App doesn’t report this and instead, only indicates that watering will then be Thursday 07:00. This cycle repeats for all 3 timers that I am running. 1 Timer to 1 Hub, and then 2 Timers to another Hub.
Regarding Weather, I’ve noticed that weather information is displayed in the Home view only for 1 timer, switching devices to any of the other 2 timers in another Group, no weather information is displayed.
