I live in Mesa, Arizona, and have this same question. I have water rights to my property and use flood irrigation supplemented with a city-water-fed Rachio-controlled irrigation system. My zones are configured so that the areas flooded are mostly on separate zones from the rest. Eg, my lawns are in separate groups for the edges of the concave yard and the middle that gets flooded.
We flood 4 separate areas every 2 weeks in summer and once a month in most of the rest of the year.
The Rachio’s automatic scheduling features get my watering needs completely wrong. Weather stations miles away don’t seem to accurately reflect conditions on my property; especially when I add the flood irrigation to the mix. At best, the Rachio gives me remote control without having to go outside to reconfigure my schedule.
Has anyone here added a personal weather station and/or moisture sensors to their system to deal with micro-climates and flood irrigation? If you have, I’d love to learn about what you did and how it is working?
