    The Nest has a built-in motion sensor. If it does not detect activity after a period of time, it will go into Auto Away mode. When activity is sensed, it will return to Home mode. If you want, you can set Away mode manually on the thermostat or through the app.

  • It senses movement in the area of the thermostat. So it really doesn't
    matter if you are away for a short or long period. It will activate again when
    movement is detected.

  • There is a motion sensor build into the device that determines how often you walk by, and when, then after a week or so can predict when you have left the house.
