Previous owner replaced all switched outlets and made them always hot. How can I figure out which switches used to control which outlets?
Is there any trick to figuring this out? Currently my best reasoned method is verifying the switch is connected, removing all the receptacles and testing for no voltage on all hot wires with the switch off. Literally every room in the house but the dining room has one "do nothing" switch. I have checked for half hots.
All rooms having working overhead lights on switches. Two rooms have unused fan switches as the fan/light fixtures are remote controlled.
