Zwave JS problems after migrating to RPi 4 (Cannot connect)

Configuration Z-Wave
1

Hello together and thanks for this really great smarthome system.
I’m in the progress of migrating from another software to HA and struggled now.

I installed HA first on RPi 3 and configured anything. But now I had a free RPi 4 to use this as a replacement. Everything worked well and I could restore the complete snapshot.

Only problem now is Zwave JS. The Add-on in the supervisor seems to work properly:

But the integration tells me:

Setup erneut versuchen: Cannot connect to host core-zwave-js:3000 ssl:default [Connect call failed ('172.30.33.0', 3000)]

I tried several things and don’t want to lose all of my configured entities. Also a complete deletion of integration and add-on didn’t work after reinstalling as the integration tells me again, that the connection failed while installing.

Can you point me to the solution here? I guess it has something to do with the dns-call after IP/RPi change? But how to solve it?

Are you using an Aeotec Gen 5 USB stick (not the newer Gen5+)? That stick requires a USB hub when used with RPi 4.

Oh sorry forgot. I use the razberry daughter board.

I’m sorry for this thread as the solution is that simple as it always was when using razberry boards.

BT had to be enabled or better said these lines had to be added to config.txt

dtoverlay=pi3-disable-bt

Thanks for your time :slight_smile:

This really helped here too
