Today the area near my parents house ( different account than the one Im posting under, can PM their account ) had a power outage. Power came back a couple of hours ago.
All of a sudden one particular zone in the yard started watering. We noticed it later ( so not sure how long it had been running). Rachio wasnt seeing the zone as running, tried to start and stop some zone manually and then stop did nothing, I cut the power to rachio and still that did nothing. Eventually had to cut the water and power to the sprinkler to get it stopped.
Any ideas what happened ?
