I hadn't realised that KNX needed specific twisted pair, as opposed to plain- vanilla cat5.
The house wiring is actually not finalised yet so I can make changes, dependant on what manufacturer I choose.
Pulling two cables (to allow looping in series vs star configurations) is a good idea.

So how does KNX compare on price vs the others?
Initially I'll probably only automate between 4-8 circuits , and add more automation / control over time.
