Reduced my energy costs!
I purchased the INSTEON thermostat so that I could shut it down as I was leaving for work. I replaced my front door light switch with a KeypadLinc and programmed one of the buttons to basically shut down my thermostat. I also added lamp modules to turn off a couple lamps in my bedroom (LampLincs) and replaced other switches throughout the house (SwitchLinc) so that when i leave for work, nothing is left running. I saved about $150 in energy costs the first month. Note: in order to "talk" to this thermostat from a KeypadLinc you need an Access Point. Oh, and I added a SmartLinc to the mix so that I can control this thermostat and my lights from my iPhone. Very cool stuff.
