From the Nest Blog:
What if Auto-Away could turn off your lights? What if your dryer knew not to run when energy prices were high? What if your robot vacuum knew when you were gone and cleaned up before you got home?
I posted my review of the Nest earlier this week. I've been using mine for about three months and love it. But I was just thinking the other day, the Nest knows my schedule, when I'm home and when I'm not, wouldn't it be cool if other devices could hook into that? Looks like this is possible with the new Nest Developer Program.
