I have had no trouble with my Rachio 3 working until today. my internet is stable but the rachio keeps going on and off line. I have 2 Rachio hooked up and 2 isolators. Everything has been perfect since I installed them a couple of weeks ago. Today, when i saw one offline i went through the troubleshoot, it reactivated but is still bouncing between offline and idle. Now both ratios are doing it; now in offline mode.
