My Rachio 3 ran multiple zones last night when our weather station was reporting temperatures well before freezing. I saw another post that this may happen if other stations in your area report higher temperatures, but I checked several Wunderground stations nearby, and they also reported sub-freezing temps. I did get a freeze skip the night before, when the weather was even warmer.
Given the liability issue of icy sidewalks and the local penalties for running a sprinkler in freezing weather, this really needs to work. Do I have something set wrong?
