Yeah, thanks for your assistance too Techstyle. I'd like for my system to save more money and energy than it spends. My goals are somewhat lofty, but I'll chip away at them. I'd like LMCE to track my location in the house and control the temperature based upon the occupied areas. If we're in the living room with the fireplace on, then I'd like the furnace to idle down. In summer, I'd like to have an outside weather station to provide temp and humidity info and let the system determine if we should use A/C or evaporative cooling. I'm already saving about $60 per month in phone bills with the VOIP. So the 1-wire system is pretty important.
