I'm using Lowes home automation system. I currently have a number of switches on it and the garage doors and thermostat. I can control everything by cell phone. I'm adding a door lock too so I can unlock and lock a door remotely (for example if I want to let a contractor in but not give them a key). My wife and I always fought over the garage door controller, now when I come home from a ride I just open the door with my cell phone.
The Lowes system is called IRIS and is pretty idiot proof, even I can do it. Only a few issues here and there but generally reliable. Funny while looking for information I was goggling ISIS instead of IRIS, so I'm probably now on a no fly list!
