I have just completed the first phase of the X-10 light switch install. After two days I’ve swapped out 8 switches and now have all the stairway lights properly wired. It was pretty touch and go there for a while: when things don’t work and patience wears out you can do some pretty dumb things, a bad idea when playing with 110 volts.
In any case, even though it isn’t pretty, things are working. Now the huge task of mess cleanup comes next. I have boxes, wire cuttings, wall remains, and a whole lot of dust and muck to clean up after. I can’t ask myself if its worth it because I know it will be… it’s just the pile of crud that awaits removal that makes me think otherwise.
