In case anyone is looking, I’ve created a How To for installing the VelServ TCP gateway for Velbus
(Not VelServer, that’s a different project entirely)
Hello All 
I’m struggling to find where I posted the link to an openHAB2 Velbus binding update script, so to help everyone, I’ll put it here
http://www.mdar.co.uk/dl/openhab2/update-velbus-jar.sh
Just run that script from your linux command line and it will pull down Cédrics latest binding from my website and put it into the openHAB addons’ folder.
Assuming it is
/usr/share/openhab2/addons
It’s easier to use this command within Linux
wget http://www.mdar.co.uk/dl/openhab2/update-velbus-jar.sh
followed by
sudo sh update-velbus-jar.sh
Don’t forget to add the V1 Serial Binding to get it working, easiest way it from PaperUI / Configuration / Addons / Bindings
You don’t need to do anything more than add it, there are no configuration files needed.
(I’ve lost count how many times I’ve forgotten that step)
