I have had two instances over the past few months when I discovered that my system was not watering my yard even though I received emails telling me that watering had been taking place.
In both cases when I finally figured out the watering was not taking place (after a week in the first instance) I pulled the power on the unit and then powered it back up and successfully started the watering cycle.
In this same time frame I had two power outages so this could easily be related to the timing my wifi network coming back online and the Rachio unit booting back up, or something else entirely.
In any case I am confused as to why the unit would not simply water on the pre-arranged schedule provided it had power and knew the time as my previous "dumb" controller would do. So my question for the support team is how can the app tell me that watering has started when the unit has in fact not started watering? I would like to turn your answer into a feature request to either fix this so it does not happen or have the app notify me that I need to reboot the Rachio controller so please see if you can give me enough info to include in the feature request.
