Hello Amy, Could I have your timers mac address to take a look at it from our end? Also just as a reminder when turning off your sensor whichever mode appears (on or off) indicates the mode it was just set to. Do you by chance have a pump? If so have you noticed any fault or error messages on the actual timer screen when it should be watering? You mentioned that you have to set test/manual watering’s for some of your plants, and I just wanted to confirm that they water only one zone/line waters at a time.
Oh, and the calendar will only display future/predicted watering’s. To check what was actually completed you will need to go to your watering history page.
