I’m having the same problem. The history is inconsistent. Sometimes it records one zone, sometimes none. My programs run at night so I need to know if they run correctly. I tried to run the irrigation program and the app didn’t register the watering event even when I saw it running. I have just realized of this issue since May 25th when I used for the first time in the year.
This issue is really frustrating. The smart watering feature is completely useless now.
