The docker communicates with the Zwave USB. There is a UI for config.
You can chose to use HA MQTT auto discovery which basically sends HA all the devices (I found this contained too many entities alarm_type alarm_level burglar_level etc that I didn’t need)
So I chose to manually add MQTT entities to HA in config.yaml
Allows me to restart HA, without taking the Zwave network down. Also it is OZW 1.6
I imagine the HA OZW setup will catch up to this functionality as the devs are all working together, but had this running nicely for quite a while now.
