For switches...(and many other things)

Inovelli being my preference, for no real reason other than I asked a support question about a complex 4-way circuit where line and load were in separate boxes on a Sunday and the president got back to me that evening.
I have both and both are great.
The in box controllers are limiting. I have an aeotec one and even in a simple single pole switch, it was a pain to have to find different gauge of wire to jump to the switch and then cram it all behind the switch. The physical toggle position also becomes meaningless which bothers my OCD as well.
The switches above can be used in 3-way, 4-way without having to replace all the switches, can be automated for multiple taps etc...
