Its a great touch to have lighting on a remote. When lighting commands are integrated with gear commands it is really a wowing affect. A cheap way to make an install feel professional.
The units mentioned in this thread can be retrofitted to any exising installation. You just have to watch for 2 wire or 3 wire requirements for install. The lutron units are affordable at $50 or so. Great value I think.
I like the idea of an RF remote, especially for locating gear out of sight. I can look at one down the road when all the other tweaks are exhausted.
A little ingenuity keeps the hobby fresh and fun command recliners interlocked with lighting would really be boss! but not gonna happen in my space.
