Installing OpenHAB – Velbus binding

Log in to openhabian with ssh i.e.:

ssh openhabian@openhabian

Install snap:

sudo apt install snapd

Install velbus-tcp:

sudo snap install velbus-tcp

Get the script from mdar.co.uk page:

wget https://mdar.co.uk/dl/velserv-setup.sh

Make it executable:

sudo chmod a+x velserv-setup.sh

WARNING! The script doesn’t perform any checks) it’s work in progress) – read the script before executing. The script setups and runs velserv

Execute the script with:

sudo ./velserv-setup.sh

Add Velbus Bridge in openHAB bindngs

Set the Velbus bridge using server: localhost and port 6000. Wait a while – it will be off line for a few seconds. That’s how it looks:

Open VelbusLink

Select connect to network

Use your server Ip or hostname, port 6000

IMPORTANT: untick the TLS box!!

Troubleshooting:

From server terminal: “systemctl status velserv” shows the status. If the velserv restarts every few seconds – it might be caused by invalid USB gateway name.

Make sure the gateway is connected:

openhabian@openhabian:~ $ lsusb -d 10cf:
Bus 001 Device 003: ID 10cf:0b1b Velleman Components, Inc. VMB1USB Velbus USB interface

openhabian@openhabian:~ $ udevadm info -q property /dev/bus/usb/001/003 | grep DEVPATH
DEVPATH=/devices/platform/scb/fd500000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0/usb1/1-1/1-1.3

That path should be the same as reported by “stemctl status velserv”. If it’s different it needs to be changed in “/etc/systemd/system/velserv.service”
