No, not really. This was a couple of years ago and I haven't done anything since. I always meant to write a blog post about it, but never got around to it.

I disconnected it completely a long time ago because it started to make the relays stick and all the switches in the house stop working. It's actually my parent's house, so I didn't want to make modifications to it or affect the current switches at all, just add a little smartness. I still want to get back to it when I get the chance.

The house was built in the mid-70s by a commercial electrician, and even the closet lights are connected to it. There are about 50 switches/relays in total. We've had to replace 3 or 4 of them in the last ten years, but that's all.

All the low-voltage wiring is out in the open. The relays are cylindrical and poke out of knockouts in the relay panel. The relays are of the latching type, so only require power to switch on/off. Three wires to each relay and switch: red/on, black/off, and white/common.
