Ask HN: What is the most impressive home automation setup you've witnessed?

[nathanathan]

Most homes I've visited used very little home automation technology. I've only seen a few motion sensors and clappers. My own experiments with x10 equipment have been pretty limited due to time and budget constraints. I'm curious what kind of state of the art systems are out there and how well they perform in practice.

I always liked the idea of music following me from room to room. Bill Gates; house (52 miles of fiber optics http://www.therichest.com/luxury/celebrity-home/the-million-...) had that feature years ago.

"a GPS system in his car could alert his networked bathtub to begin filling itself with hot water as Gates approached his home."
