Help! My power is back on but I’ve lost internet access. I need to know how to turn the Rachio 3 off at the wall unit. I turned everything off online but since the unit isn’t communicating with the app, my sprinklers actually tried to run in freezing weather this morning. No idea the extent of that damage but I need to know now to stop this from happening again as I have no idea when internet will resume to communicate with the device.
