Nest Thermostat

The Nest Learning Thermostat (or Nest Thermostat) is a smart thermostat developed by Nest Labs.] It is an electronic, programmable, and self-learning Wi-Fi-enabled thermostat that optimizes heating and cooling of homes and businesses to conserve energy. The device is based on a machine learning algorithm: for the first weeks users have to regulate the thermostat in order to provide the reference data set.

The thermostat can then learn people’s schedule, at which temperature they are used to and when. Using built-in sensors and phones’ locations, it can shift into energy saving mode when it realizes nobody is at home.
