I have two Rachio 3 units on separate buildings, with separate electrical meters and separate wifi networks. They are a few months old. Both experienced a power outage and both now seem to be dead. Nothing seems to get them connected again. Just blinking red light. I’m still waiting to hear from tech support. I’m really disappointed.
Update: just received an email from tech support suggesting an the steps I’ve already taken. If these things can’t handle a power outage then I don’t want them. I’m not taking a chance with this happening outside warranty period. I’ll find a more reliable product. I have dozens of electrical devices (smart and otherwise) plugged in at my house. The Rachio controllers are the only things that failed. This is a deal breaker.
