It seems as if the app doesn’t always accurately reflect the state of the controller.
Two issues I’ve got right now:
I set a 3 day rain delay. It showed correctly on the app when I set it. Right now there are 47 hours left, per the controller. The app shows no rain delay.
I manually started a zone. Selected to run it for 10 seconds. The zone starts but the app immediately returns to the home screen as if nothing is manually running. There is no way to turn it off from the app. The controller shows it running, shows correct time remaining, and is the only way to shut it off.
