Mine is less of a question and more of a request. I would like notifications from the app that tells me when the Sprite has started watering or has skipped a watering. After setting up my Sprite this weekend, it skipped the first watering for low temps, but I had no idea of that. Also, I run my sprinklers in the early morning and it would be much easier to read the notification that it did water than have to go into the app and check it manually. This is the only thing I will miss after switching from a Rachio controller, otherwise it is everything I need.
I understand you don't want to spam us with notifications, but you could add a "Notifications" tab in the settings page where we could choose the notifications we want to receive. I would at least like the choice.
