Pop off your old thermostat and install your new Nest. It should take about half an hour. Now turn up the temperature and get comfortable.

You turn down the heat on your way to bed. Nest gets to know what you like and starts building a schedule: cozy in the morning and cool at night. Put a Nest Temperature Sensor in any room, like the baby’s room, and you can tell Nest to make that room a priority (sold separately).

After you turned up the heat a few days in a row, Nest learned you like eating breakfast at 70º. So now it warms up the house as you get out of bed.

You’re off to work. The Nest Learning Thermostat can use sensors and your phone’s location to check if you’ve left, then sets itself to an Eco Temperature to save energy.

The babysitter calls to say she picked up the kids from soccer and they’re heading home. You adjust the temperature from your phone so they’ll be cozy.
