About home automation of light switches: I put in ~10 X-10 devices, plus the ~20 controllers to activate them, circa 2002. I did it myself (I'm an EE), so the installation cost was 0.

It worked OK for a while, but the setup was not robust and eventually some controllers would not work some devices at some times. The annoyance factor in going from 0 errors to a 1% error rate is HUGE.

Five years passed, and I have been slowly replacing all these X-10 devices with hard-wired switches or with Insteon. Of course, the original 1959 wiring paths (12 gauge Cu FTW) still work fine.

Now, when I see connected/automated homes in design mags, all that tech seems more like a long-term maintenance headache than a desirable feature. If I had an unlimited budget, I would not build those features in, I would just install conduit and run old-school copper wires through it.

My lessons: (1) The design life for a home is decades, the refresh rate for home automation devices is years; (2) Upgrading/tinkering is fun the first time -- but only the first time; (3) Your spouse hates it more than you do; (4) The existing device does one thing without fail, replacing it with a device that does more things but sometimes fails is not a net gain.
