And now, for why this fits with the Green Dream: This will save hundreds of feet of copper wire and tons of labor time on the install. The first thing I thought of was the ability to fully shut down all the power that my house is burning when I drive off--the satellite box, the light that I left on near the bed, etc. With a simple click I'm saving money! They say that the total cost for a 3,000 square foot home is about $3,000. The sad part? The system is designed for new constructions only--no retrofits!
