NEST - How does it know that the house is empty?

My old Thermostat is fixed on the wall, and i might get this new piece of technology... but some features seems... too magical to be real.

    It has built in motion sensors, both near and far field. It's similar to your iPhone knowing when it's close to your ear. After sensing a lack of motion for more than a few hours, it sets itself automatically to away. Pretty cool!

  • It is auto sensing. (they call is auto sensors) For example when you walk up to it it will automatically turn on and display the temperature. If you are away for 2 hours it will automatically move to "away" setting. So, its actually assuming you are away when you could be a sleep in the other room and its not sensing things.

    Thats not to say when you are sleeping it will adjust the temperature on you because it hasn't seen you. It learns your trends so its not magic its just prediction.

    Hope that helps explain.
