So I just ran into this issue with my Home Assistant Setup. I logged in for the first time in about a week and found that I had an update available for the Open Z Wave Add-On. Oddly enough the check box that says Auto Update does nothing.
Anyway so I updated thinking everything would be okay….. WRONG!!!
After doing the upgrade and rebooting the appliance the Open Z Wave admin console would fail to load and the service would not start. I tried several times as that is normally what I have to do. Which by the way the the start on boot up also never works.
I checked the Home Assistant forums and found this thread. It turns out that the the issue is actually with MQTT. Apparently MQTT is presenting an invalid response which is causing Open Z Wave to barf. One of the options listed was to use an MQTT Browser to delete the entry and that has worked for some people to varying levels of success.
It did not work for me, but here is what I did:
- Back up your configurations before you do any of this.
- Step 1: Uninstall Open Z Wave from Supervisor > Add-ons
- Step 2: Uninstall MQTT
- Step 3: Reboot Home Assistant hardware
- Step 4: Install MQTT again and make sure it is configured and then Start the services.
- Step 5: Install Open Z Wave and make sure it is pointing to the correct ZWave Antenna and start service.
I then checked the Z Wave log to make sure the error was gone (and it was!!)
UPDATE!! Within about an hour of making this post I discovered that my whole Zwave setup was not working and the service eventually crashed. This morning I ended up doing a fresh install and I was able to pull down OpenZwave 0.5.1 and that seems to be working. I will update once I have more information.
I hope you found this post helpful, and if so please share with your friends.
