I’ve never tried the Openhabian OS version.
I’m always much happier with a DietPi (version of Debian) running on the Odroid C4 devices and install whatever I need on top of that.
The DietPi software menu includes openHAB & HomeAssistant, which I do have running in the same machine here, as a test.
(Both talking with the official Velbus Snap package, Velbus-tcp)
Did you opt for VelServ or Velbus-tcp as your TCP gateway?
@PrzemoF
Can you edit you webpage please?
You’ve confused the setup instructions for VelServ and Velbus-tcp
VelServ is a C++ program, that can run stand alone or with the service file my script installs
wget https://mdar.co.uk/dl/velserv-setup.sh
Verses the official Velbus Snap package which runs within the SnapD environment
My install script will do all the magic for you.
wget https://mdar.co.uk/dl/velbus/velbus-tcp.sh
Worth noting this forum post too
