I had a contractor and he did all the electrics as well. This meant that the cost for labour wasn’t really much more than getting all the “dumb” electrics done.

Ultimately wiring for KNX doesn’t take a lot more than just running a single extra wire through large sections of rooms since it’s a bus based system. We worked on an hourly rate + cost of materials, rather than a fixed contract. All the other home automation people I talked to didn’t really “get it”. This guy opened up to me about the importance of open standards from the first time I talked him and was happy at the concept of me programming the KNX devices myself, so I knew as soon as I met him that he was the right guy for the job. I worked really closely with him (a daily catchup every day) in order to make sure everything was perfect. I was really happy with the process, but it relied on getting a guy I could work really well with.
