My Gen 2 controller has been working almost flawlessly since the day I bought it shortly after its release. A few years ago, I added an Ambient Weather station to my backyard (thanks to Gene’s help), which had a major positive effect on the overall function of the Rachio, due to the weird micro climates here in Missouri.
Now, all of a sudden, the controller has gone haywire on me. Over the past few weeks, I’ve noticed some bizarre watering activity, along with the known issue (for some) of the main calendar being off (only on the Win 10 desktop, but not on my Android phone). The controller is not properly keeping consistent track of saturation levels, and even if I do a manual fill, the controller still insists on watering in spite of precipitation and irrigation tracking accurately.
Last night, we had rain beginning at around 11pm, and continuing through the night with thunderstorms and driving rain at times. When I turned in for the night, Saturation levels in all zones were around 74%. Much to my surprise, I woke up this morning to driving rains and thunderstorms with my lawn being watered by the controller, which showed zones at 110% saturation. I immediately put the controller into standby.
A few hours later, when the controller was still showing 110% saturation, .35 irrigation (which I had interrupted), and 1.22 precipitation, I took the controller out of standby to see what would happen. It immediately began to water. It’s still raining, and as I write this, precip is showing as 1.40.
I’ve been running a flex monthly schedule since day one, with excellent results, and haven’t made any changes in quite some time (at least a year) since I have had no need to.
Anybody have any ideas? For now, I’m going to have to keep the controller in standby and work my 11 zones manually.
Thanks in advance for your help.
