First, I’ve been using the Rachio since October of last year. It’s been nothing but headaches, honestly. For one, the flex schedules simply don’t work right. In Phoenix, I could never get it to water more than every few days without “forcing” more water by setting the allowed depletion down all the way. Here, people water their grass 2-4 times per day, every day, for 10+ minutes. This is what it takes to keep burmuda grass green when it’s 110+ outside and very low humidity. After my burmuda turned nearly completely brown, I went back to manual schedules and watered four times per day, every day, for 20 minutes until I got it green again, then backed it down to twice per day for 10 minutes. What’s the point of a “smart” system using fancy math when the math doesn’t check out? I even had our local water company come out to validate the system (they were interested in learning about it, so they came out) and we did the whole catch cup thing, etc. Point is, calculating out available water, crop coefficients, root depths, efficiency, etc is FAR too much for the average consumer, and I believe I am well above the “average” consumer. Landscapers around here barely speak English – they have no clue what ET is or how to do anything more than say “grass is brown; water more”. That leaves all the programming to me and I’ve spent countless hours giving this thing a shot.
Today may have been the final step to get rid of this – it’s pouring rain and guess what? My sprinklers went on! I logged in to Rachio and it says we have 100% precipitation! Go figure! And yes, my programs do have rain skip weather intelligence turned on. What gives???
Anyone else about to trow this thing out the window? I have no idea what the logic is in using fancy ET math when a simple 12" probe in each zone would tell you A LOT more…
