When the rain sensor is on (it is wet) cannot use manual valve opening.
For a second the valve opens and the same or next second closes with a message about the rain sensor is on.
I think manual override (valve opening) should be enabled even when the rain sensor still on.
@jrakoczi, thanks for your feedback. We use to operate this way, but had requests for the rain sensor to turn off watering times anytime it was wet. Changing this will require a firmware update. I’ll share your feedback with the product time for future consideration.
If anyone else is having a problem with this, please let us know.
