It just seems smart to me to put your home thermostat and other power hungry items onto some sort of automated system:
1-wire thermostat control

for some reason, computer controllable thermostats are pretty freakin' expensive. i found a reference to a 1-wire thermostat in this(mirror) sample senior project on home automation. it turns out that dallas semiconductor put one together a while back as an application for their tini platform. (web-application server on a chip). the write-up has since vanished from their site, but i found it thatnks to archive.org. the thermostat used to run about $50, and a similar model still seems to be produced. the 1-wire interface is pretty simple - maxim's tini board to control it: not so much. just using the 1-wire interface with an inexpensive thermostat and controlling from a pc seems pretty viable to me. just in case, i mirrored the 1-wire interface schematics here.
