Yes! I just installed my new rachio and I love it, but I have this same problem and have not found a clear answer.
I don't want a notification from the system when things are normal (watering turned on, watering turned off), but I would like to get a notification when something changes such as the watering schedule.
It seems that turning on any notifications at all automatically turns on the "routine" notifications. Is that true, or am I misunderstanding one of the notification settings?
