I want to control 3 sets of pot lights with 3 dimmers, 1 set of 2 at the front of my HT, another set of 2 in the middle & a set of 3 at the back. I'd like to set up at least 2 different lighting scenes depending on whether I'm watching TV or a movie.
I have 3 dimmers, & have the IR543 on order. Do I need the 4071 to set the scenes, or should I be good to go with just the IR543?

Thanks.
