I'm JUST getting into a little home automation, and here are some great use cases that aren't just a novelty: When my wife and I both leave the house, the front door locks itself. We never have to worry about if we locked the door or not. We can also leave and enter without having to carry keys, which is great. I can also unlock the door remotely when my in-laws stop by unexpectedly to drop something off. I have a room in the basement where the light switch is on the far side of the room, so you previously had to traverse a pitch black and somewhat hazardous space to reach the light switch. Now it's all run on a motion detector that turns the light on and off as needed automatically. And we just got a Nest. My wife, a non-tech person, loves the front door lock magic and the Nest. As more stuff comes out, and I add more stuff to the system, the utility will only increase. I'm looking forward to things like smart security systems that know when I'm home, away, sleeping, awake, have company, etc... And interact with tokens (for instance if it's 2 AM and someone pulls into my driveway, I want to be woken up and alerted. If it's 2 AM and I'm pulling into my driveway I want my wife to be able to sleep). I'm looking forward to music that follows me through the house, and turns itself down when I get a phone call.
