New HomeAssistant install doesn't recognize any velbus devices

English

Hey everyone,
the SD-card of my Home Assistant died on me. So I reinstalled and restored my backup. Unfortunately that didn’t restore my velbus integration.
I decided to do a complete reinstall but even now I still have issues with my velbus integration.
I’m using a USB-connection to my velbus with a raspberry pi. Just to be sure I switched the cable to my laptop and here I can still connect to my Velbus. So nothing wrong with the cable or the module.

The problem I have is that he doesn’t detect any devices as you can see in the printscreen.

This is what I see In my logs:

Anyone any ideas?

Hi,

I’m currently working on fixing multiple issues with the velbus integration in Home Assistant.

Make sure you use the latest version of Home Assistant.

See the same issue. Using the use the VLP (velbus config file from velbuslink) during the installation of Velbus in HA is working fine here.

Did you see my reply on the HA Forum?

Is the Velbus Hub using the correct TTY port?

Hey everyone,
Sorry for the late answer but I got swamped at work.
To answer Stef’s comment:
Yes I have all the latest versions installed, so that’s not certainly the problem. Initially I thought it was maybe related to a version that was to recent.
Any idea when there will be a new version coming out?
To answer MDAR’s question
Yes I also saw so your comment on the HA forum and I’m using indeed the /dev/ttyUSB0
as that’s the only option you get when you want to configure the velbus plugin.
Before my system crashed I didn’t need the TCP gateway as I could use both at the same time (HA & VelbusLink).
As I’m not into Linux could you explain a bit more? So I need to install a SNAP package (velbus-tcp) how do I do that on HA?

Depends if it running a vanilla Debian Linux with HA on top or if you’ve opted for the ready rolled HA image

It’s the ready rolled one that I’ve installed.

Arrrr, in that case…

You have the work out how to install the SSH server first, so you can install extra software at base level.

That’s not something I’m familiar with.

(Others have done it, so the information is out there)

Once you’ve got command line access, it should be fairly easy.

I’ve put instructions on this forum

Have a good read of all of this thread
