The Nest Learning Thermostat, built by a group led by the man who also headed up the original iPod and iPhone teams, is designed to improve home energy efficiency by giving households a heating or cooling controller that adapts to usage patterns and incorporates information gathered from the Internet. The device has a good deal of the DNA of the iPod and other Apple devices.
The digital display shows blue when the system is cooling a house, and red when it is heating. It also shows how long it will take to get to a desired temperature.
