A follow up: I got the #velbus starter kit. Looks great, works without any problems, but it requires windows to run #velbuslink - the configuration software. Fortunately nothing is encrypted. So far I didn't manage to run the software under #wine #domotics #homeautomation

#KNX is not that open as it looks on the first glance. #velbus might be the open system that I'm looking for. Any users?
