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.
same thing with me dropped about three weeks ago, did the troubleshooting got it back online and woke up today to it being offline again.
Did you ever find out what the problem was on yours
