How many things do you plug in that you can 'control' by turning power on and off or dimming?
IMO the key is lighting, sensors and integrated controllers. and a smattering of plug ins for lamps if you have them.
Walk into a room and instead of a bank of 4,5 switches- a bunch of 3 and 4 ways, Id prefer a single scene controller.
I took a quick look at Legrand stuff, is it zwave ? zigbee?, or some proprietary system? IMO you want something NON-proprietary so you can add to it, not be stuck paying $120 a switch when a zwave is $39.
Lots of choices and paths....do your research. Enjoy!
