I setup my Rachio in December and it watered once on Dec 13 and hasn’t scheduled any watering since. I’m in San Diego, it’s been fairly warm, there hasn’t been much rain, and the soil is pretty dry. I actually watered a couple of times manually without Rachio just to see when it would finally schedule a run.
Here’s an example of a zone:
North Back Yard:
Last watered: Dec 11 (6 weeks ago)
Soil Moisture: 66%
Spray Head: Bubbler
Exposure: Lots of sun
Available water: 0.17in/in
Root Depth: 15in
Allowed Depletion: 50%
Crop Coefficient: 50%
Nozzle inches/hr: 1in
I have 9 other zones that are very similar.
I didn’t change anything - Just setup Rachio and I can’t imagine a scenario where it determines my yard only needs water once every few months.
I’m happy to spend time to dial this in, but the defaults are so far off, I feel I must be missing something huge
