I have been using a Rachio (2 of them actually) for over a year with no issues. Last week, while I was in the app setting up a quick run, the controller disconnected from wifi and would not reconnect. I get the pulsing second light thing.
I called tech support and they indicated that newer apple products were to blame, so I tried my old iPad, same issue. Tech said my unit was faulty and would replace it.
It came in the UPS today, I hooked it up as I am tired of manually running my 13 zones, same exact issue both with my iPhone X and my older iPad. It will not recognize my controller.
I tried forcing it into wifi reset, nothing. I tried turning cellular off, nothing. I tried unplugging my mesh point and going straight to the router, nothing.
Of course, Rachio is closed for support at this hour. Any idea what is going on?
