Nest Learning Thermostat

The Nest Learning Thermostat may be small, but it's jam-packed with cool technology, including activity sensors, a Wi-Fi radio, three temperature sensors, and a humidity sensor (you can also use it to control a whole house humidifier/dehumidifier system).

The Nest senses your presence and displays the current room temperature along with the desired temperature setting.

There are no buttons or dials on this thermostat; the Nest's stainless steel outer ring provides all the functionality you'll need to set up and program the device.

In order to help you save money, a green leaf will appear when you set the temperature to a level that is considered energy efficient, like 68-degrees.

The Nest will work in most dwellings that employ a two- or three-stage heating/cooling system.

The Nest connects to your wireless network, so once you've performed the initial setup you can open a Nest account and manage everything over the Web. Mobile users can download iOS and Android apps for their phone or tablet.

Once the schedule is created you can still make arbitrary changes from time to time (one-offs) and the Nest will stay the course. You can change the schedule at any time using the Nest's ring, but it is much easier to do online.
