I recently move to a house that had a lot of pre-installed smart switches, locks, etc. So far everything is working fine, but I can not figure out how to pair a sensor that’s in the living room:
It look like a Centralite 3305-S 3-Series motion sensor although the front trim looks different. Still, it carries the 3305-S model and centralite is printed on the PCB. There’s a good chance it’s a variant of that.
