I’m at the end of my rope with this thing. Here in SoCal, it rained for two straight days. We had at least 2 inches of rain. I woke up this morning to see Rachio watering every zone in my already flooded yard. When I checked the moisture level in the app, most of my zones were listed at 9 percent or 19 percent, etc. The 2 inches of rain apparently did not add any moisture.
I manually changed the moisture level of each zone to 100 percent so it would not turn on again today.
