I did more reading and felt in love with KNX, but I'm still trying to find CSA (Canadian) approved devices. Everything without CSA stamp will not pass building inspection
. Everything related to smart home here is INSTEON, X10, HAI and really expensive Lutron, Creston systems.
It would be great to see a complete setup with heating (floor and hvac), lighting and media. Which devices are used and how they are connected. When I start to read about it was hard to see what I need for a complete setup. But I'm doing small learning steps.
