Nest Learning Thermostat - wikipedia Nest Learning Thermostat Nest Learning Thermostat The nest thermostat 's front screen Developer Nest Labs Type Smart thermostat The nest learning thermostat is a smart thermostat developed by Nest Labs and designed by Tony Fadell, Ben Filson, and Fred Bould. The device is an electronic, programmable, and self - learning Wi - Fi - enabled thermostat that optimizes heating and cooling of homes and businesses to conserve energy. It 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. Nest 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.

Nest consists of two primary pieces of hardware. The display contains the main printed circuit board ( PCB ) and rotating ring, and the base ( pictured ) houses the connection terminals, bubble level, and holes for wall anchors. Neither can function independently ; if separated, the display becomes inactive until reconnected to the base. A special version of Nest is available in Europe, which is capable of controlling 120 -- 240 V heating systems. The Nest is paired with a `` Heat Link '' device, which contains the circuitry required for controlling the mains - voltage heating system. Software The Nest Thermostat is built around an operating system that allows interaction with the thermostat via spinning and clicking of its control wheel, which brings up option menus for switching from heating to cooling, access to device settings, energy history, and scheduling. Users can control Nest without a touch screen or other input device. As the thermostat is connected to the Internet, the company can push updates to fix bugs, improve performance and add additional features. For updates to occur automatically, the thermostat must be connected to Wi ‐ Fi and the battery must have at least a 3.7 V charge to give enough power to complete the download and installation of the update. The Nest Thermostat has had a number of software updates. A recent security update enables two factor authentication. Many have commented on the company 's `` Nest Community '' regarding the lack of prominent display of the current temperature. The operating system itself is based on Linux 2.6. 37 and many other free software components. To comply with the terms of the GPLv3 license under which some components are available, Nest Labs also provides a special firmware image which will unlock the system so that it will accept unsigned firmware images. While the thermostat software by Nest Labs itself remains proprietary, a third party has reimplemented the basic logic in an open source replacement called FreeAbode. Weave Nest devices interconnect with each other using a protocol called Weave, which is based on IEEE 802.15. 4 and Wi - Fi 802.11 b / g / n. Availability Nest is available for sale in the United States, Canada, Mexico, the United Kingdom, Belgium, France, Ireland, the Netherlands, Germany, Austria, Italy, and Spain. It is, however, compatible with many heating and cooling automation systems in other countries. Nest Labs have surveyed existing users known to be outside the areas where it is officially available. Use of the thermostat outside the United States and Canada is complicated by the software setting time and other functions based on the ZIP code. For international users this means they must either disable Wi ‐ Fi to set the time correctly or use the nearest U.S. zipcode which may result in erratic behavior as the thermostat makes faulty assumptions about inactivity corresponding with either sleep or the home 's occupants being away. In 2013 a man - in - the - middle hack potentially allowed worldwide users to set up their timezone and local weather. In an effort to increase the number of homes using their learning thermostats, Nest began to partner with energy companies. In February 2014, Direct Energy and Nest laboratories launched their Comfort and Control plan. The plan allowed Canadian customers in Alberta to receive a learning thermostat when they signed up for a five - year electricity contract. In April 2014, Nest announced a partnership with the United Kingdom energy supplier nPower. The partnership offers customers a cut on the Nest installation price and locked energy prices for 5 years, when customers receive both gas and electricity from nPower and paying with direct debit. In June 2014, Direct Energy and Nest Laboratories expanded the package to Direct Energy 's United States market.
