Hi,

I just accidently deleted the "ZWave Network Access App".
After readding it, all ZWave devices are gone in the HA UI. The expert UI gives me an error: "Error handling data from server".

The log shows several errors:

Code: Select all

Do I have to reinclude all devices?

I have some more information on the log:

I have the 1st gen razberry module, configured as /dev/ttyAMA0

After some research I found out that a cold restart would fix the problem.
However, all device configurations are lost.
I got a backup, which folders do I have to restore?

Depends what is missing. If Z-Wave data, then config/zddx and (or full config).
