None existing z-wave node

For some reason, the NodeID 29 (Namron Z-Wave relay) definitiv lost the connection, because it shows Unknown in the column Route.
You can try this out::
– Restart Homey or better disconnect it from the power supply for 10-15 minutes
– Disconnect the Namron relay from the power supply for a few seconds

If nothing helps, you will most likely have to remove the relay and add it again.
If adding the relay does not work, please follow this help tutorial:

However, please report the issue to Athom Support.
