I have been dealing with Z-Wave since I started in 2021 with OH3, and some months ago I decided to move to Z-Wave JS UI. Somethimes I love it but sometimes I will kill it, since there is always an unstable behaviour with random disconnections of nodes in this situations:

- Power supply goes off
- Restart of Openhab service
- Restart of Z-Wave JS UI service

Then it is very difficult to recover communication, with nodes waiting sometimes for days, and even missing information after recovery: configuration info, channels, etc.

Sometimes I have to delete the node and re-link again in to recover all its info.

Danalock V3 behaviour is always a nightmare, and qubinos or shellys are oftenly missing link.

Are there any specific tips to improve the general performance of the system?

Thank you all

Diego
