I am running a flex daily schedule, which only waters 3x each week. I have used the Rachio defaults on most zones, with correct sprinkler heads, root depth at 4-5”, etc.
However, it appears that when the hot weather comes, Rachio does nothing to handle the extra ET. Soil moisture stays at 0% (Irrigation < ET), and grass starts to die.
Why are the run times capped and the ET ignored? Maybe it is the same problem with them not allowing a negative soil moisture. The checkbook looks so good, but ignores any debt! The ET is 0.2”-0.3”/day and only 0.25” is irrigated (3x). One week is 1.4”-2.0” ET, and irrigation is only 0.75”!
How about making a “ET - Precipitation Schedule”? Because that’s what I thought it was!
