Google "Nest Detect" sensors

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.

I think the Nest Secure products used a protocol called Weave on top of Thread. Weave was an application layer protocol like Matter and was open sourced by Google, but I don’t think any other projects picked it up and integrated with it. There is no Home Assistant support as far as I can tell.

It’s a shame as the Detect sensors are cute little devices.
- ah, damn. thanks for the info!
Homebridge might be worth a shot. I know its Nest integration is better in some ways than HA's native integration.
