What's this?

Just curious, any ideas?. 1995 built home. not for ceiling fans…


Audio volume control. Looks like an infrared receiver or repeater next door.

Motion detecting light switch with dimmer?

Looks like they ran out of white filler plates and used what they had.:wink:

All of the above! I didn’t get any response from the dial. I told my client to bash it in with a hammer and see if anything quits working. j/k
