I’m having similar problems. There seem to be too many settings to get this to work as expected.
I have my zones set to “flex daily.” It rained all day yesterday and I just got notifications this evening that the system was about to run through all of my schedules (with no adjustment to duration even). It’s such a bummer to see the system waste water when that’s the exact thing I was trying to avoid.
I’ve played with a bunch of the advanced settings (which I don’t believe I should have to do) and I’ve never been able to set it up in a way that I trust it will make the right decisions.
I’ve simply gotten used to manually adjusting and skipping schedules as necessary.
