After the upgrade, HA is communicating with the devices.
Under integrations it shows:
Z-Wave Network is Started
All nodes are showing up under the config.
Log shows errors:
You post isn’t clear, are you saying node 6 is now showing up as unknown? I just upgrade my HA to 103 and have a mix of zwave and zigbee devices…all are working fine.
Have you tried to downgrade to see if your problem goes away?
