I’m totally frustrated with the so called “smart” watering. It seemed like it worked in the past. Not sure if the updated the firmware in the unit or what. No troubleshooting guides, the manual is a joke, no one answers the phone etc. I’ve notice that the saturation will be like 60% one day, no rain and the next morning it will show 100%. The “smart” controller will say the watering is schedule for the next day, no rain, and then when the next day comes it will say watering is scheduled for the next. Horrible.
