I'm looking for a battery powered Zigbee beam/trip sensor similar to garage safety sensors - does such a thing exist?
I've searched both the forums and google but come up empty. That said, I'm not even sure what they would be called (every combination of beam/IR/laser/trip came up short)
It's entirely possible they don't exist due to power requirements, I have no idea how much power the garage safety sensors pull.
Thanks in Advance,
