I emailed this directly to support but I thought I would try here as well. I am a new Rachio user this year, and so far everything has mechanically been working fine, but I'm seeing some weird issues with scheduling.
I have all my zones setup, everything looks good in the App. I also chose a reliable weather station about 1.5 miles from my home.
I have a flex schedule setup to water odd days between 1am-4am... (per town law)
Since last watering about a week ago, Rachio has been pushing out the date to the next watering probably due to cooler weather, etc. This is fine, but the next date on the App stated it would not water until Aug 25th. (this was on August 22nd when I last checked it, yesterday).
In the evening on the 22nd we had really heavy rains, it rained for hours. Not sure on the total precipitation, but I'm sure it was an inch or more. (I will check it today).
The weird thing is, I woke up today on the 23rd to find out my Rachio had watered all zones per my flex schedule. This is baffling to me.... why? Why would it move the date up from the 25th to the 23rd right after we had a heavy rainstorm??? Broken???? Makes no sense to me. This is exactly the kind of problem I was hoping to avoid by installing and using the Rachio.
