With my system, I tried to water every other day AND use smart watering. But it didn’t work. I had to do one or the other. I had to turn the program OFF and leave smart watering ON in order to get smart watering to work.
My trick is to add drippers to the plants that I want to have a lot of water, and be happy with the amount of time the smart watering decides is right.
I use the “Calendar” page to check the actual number of minutes of watering, but it doesn’t read the truth until well after the watering is done.
Good luck, techieguy.
