I got a Rachio 3 about two years ago, when I changed all my lawn sprinklers over to RainBIrd rotary nozzels to save water. I live in Sunnyvale, California (Silicon Valley).
Watering seemed to be OK up until a few months ago, when my lawn started browning in spots, and my vegetable garden plants started showing real signs of distress from lack of water. the lawn is the Rainbird rotary nozzles, and the gardens are all on drip watering.
Over the past month I’ve been fiddling with Rachio zone settings, but haven’t really been happy with the result. So, in desperation, six days ago I changed the gardens to be just a straight “every 2 day Flex Monthly” schedule. I figured I’d just override all the “smarts” in the controller and have it run every other day.
Imagine my surprise when I looked at my garden this morning and saw nothing but wilted plants! I checked Rachio, and the last time the garden schedule ran was SEVEN DAYS AGO! After I asked it to run every 2 days.
I looked, and saw that the schedule had been skipped on the 21st, 23rd and 25th because of a “climate skip.” Clearly, the “weather intelligence” decided that the garden had enough water, and I had all the WI skips enabled.
The high temperatures for the last 7 days were: 83/84/88/89/88/88/85 and we’ve had winds averaging 8 mph over that time. Oh…and, this being Silicon Valley in the summer, there has of course been no rain.
I quickly turned off ALL the weather intelligence settings for all my zones, because I simply don’t trust it anymore. How can Rachio think that it’s OK to not water a vegetable garden for over a week, when there hasn’t been rain, and the temperatures have been in the high 80s the entire time?
That’s just nuts.
So, I am extremely suspicious of the accuracy of the algorithms used by Rachio for determining weather skips, especially in a climate that has literally no rain from about April through September.
Any advice, other than just running Rachio like a dumb controller?
