...I use mine for lighting control, but good, ol' fashioned Lutron IR in my HT room (hardly the "home automation of the future" promised in the, well, past, but certainly enough to wow friends that don't spend time in the switch dept. of home depot.
As I think I said above (tooo...tired...to...scroll...) the UI codes were particularly bad for the Lutron stuff, so I was forced to use learning mode like a sucker.
The Z-wave stuff certainly looks cool, but I honestly couldn't think of anything that wouldn't cost a fortune to control, and with line-of-sight to my equipment rack it was an expense I didn't feel like forking out for.
I'd be interested in hearing about how people use the RF component, it may sway me one day....
