Home automation

This past Saturday, Amy,Jonathan, and myself successfully changed a light switch in my house.  The switch is a remote accessible dimmer.  This has to be the most practical project I've been involved with.  The customer is very happy.  Living in the woods is a beautiful place to be, but, very dark at night when you forget to leave lights on or if you end up out longer than expected.  I found the range to be much longer than the 30 feet the instructions say.
