I have a bunch of Nest Detect (A0028) sensors from the now defunct Google Nest home security system.
Anybody know what radio protocol these things use? Zigbee? Z-Wave? some other thing?
I have a Z-Wave USB dongle, or I could get a Zigbee one, but I’m not sure if either of them actually communicates with these devices.
I hate to throw them away, as they’re well designed.
Homebridge might be worth a shot. I know its Nest integration is better in some ways than HA’s native integration.
