But, is it possible to use it with Home Assistant ?
To see datas (alarm, temperature, detected motion) or use feature (use the motion detector to activate an notification, activate the light on scenarios, etc).
It’s not an integration but rather supported via Zwave-JS. You can view supported devices here https://devices.zwave-js.io/
Below you can see the entities exposed by default. One thing I have noticed is that the temperature is a constant 3-4 degrees above what is measured by thermostats in the room.
