I didn’t even consider Lutron’s offerings that aren’t smart.
Here’s my fun in one of my four rooms. It’s the main living room with a doorway at either end. It has an RF fan/light combo on the ceiling with only two black wires entering the canopy. Fan mounted directly to the joist with plaster ceiling in between that has a hole covered by the canopy where the two black wires run into the fan.
On the wall next to one of the doorways there’s a spot in the plaster that’s been drywalled over. My guess is one of the two black wires in the ceiling is from this covered up area, and likely just capped off (or taped) behind the drywall.
On the wall next to the other doorway there’s a single gang with a dumb of/off light switch, but the switch never worked and I couldn’t turn off the ceiling fan. The fan spun, the light was always off, and I had no control of anything.
When I removed the switch from the gang, I found that the wires behind it were just tied together and not even connected to the light switch. That’s when I searched and found an RF remote!
I think the elderly lady that lived here needed a remote because of mobility problems so someone took both wall switches out of play leaving them constantly hot, and then gave her the remote for controlling the fan/light.
I don’t know of the light and fan had their own wall switches on opposite sides of the room (weird) or it they both controlled all the power in a normal 3-way setup with a traveler.
Anyone have any insights?!
