I have a couple issues:
Yesterday I knew that I wanted to have the sprinklers run this morning, so I emptied each zone. The calendar updated and showed me that the plan would run. This morning I woke to see that it had changed again to run tomorrow instead. I'm confused as to why it would adjust another day out when it was at 0% for all zones.
The other issue is that on the "more detail" it is showing small amounts of precipitation that the weather station is not providing. I don't think this has anything to do with the change in watering days, but it's really weird to see that it's reporting tenths if an inch of rain when that's just not happening.
