Well I initially purchased the Rachio with hopes of the software adapting to weather variation in San Diego (I realize that may sound ridiculous). But it seems that the water budgeting feature is instead reacting only to average seasonal variation. Due to drought restrictions I can not really use the flex schedule as I can only water on Sun/Th.
Throughout the end of last summer and extending through October there were multiple episodes of Santa Ana conditions with temperatures approaching 95 to 100 degrees and very low humidity. The Rachio kept decreasing the watering times as if just reacting to average seasonal variation. When we had rain in September and then a rapid onset of colder weather in November, there was no significant adjustment the other way either.
In August and October I ended up with dead grass from underwatering. In November I ended up with a dead palm tree from overwatering.
I feel like I have to go in and manually override the water budgeting almost any time we get rain or a Santa Ana to account for weather changes.
Is ET not being measured and used to calculate watering times based on the actual weather? I have a Davis weather station in my backyard that measures UV and solar and reports to PWS weather.
What is “Water Budgeting” based on? Over the past several months, it does not seem to reliably adjust for temperature and precipitation variation in manner that is effective for San Diego with my current setup.
Should I have things set up in a different manner?
