I’m in the same boat the where openzwave addon would constantly quit immediately after starting up. I believe it’s because it’s running a internal mqtt broker and it’s not cleaning the topics up itself. I don’t know enough how to manipulate the internal mqtt broker inside the container.
I just modified the docker-compose file from get opzwave beta working and ran the openzwave container and not use the addon. I just switched to a supervised build of ubuntu so I can run my own docker apps outside of haasio I was using previously
So far so good, openzwave 1.6 container seems to be working well, and home assistant sees all my zwave devices without any issues. I do have to download the ozw-admin on my windows box and run it separately but it actually seems to work better than the vnc plugin.
