Nest Learning Thermostat (or Nest Thermostat ) is an intelligent thermostat developed by Nest Labs and designed by Tony Fadell, Ben Filson and Fred Bould. These are self-serviceable, programmable, and self-directed Wi-Fi-enabled thermostats that optimize home and business heating and cooling to save energy.
The device is based on the machine learning algorithm: for the first few weeks the user must set the thermostat to provide the reference data set. The thermostat can then study the schedule of people, at which temperature they are used to and when. Using built-in sensors and cell phone location, can switch to energy-saving mode when realizing no one at home.

Specifications
- Note: Generation E can support two-stage cooling OR two-stage heating OR heatpump because the multi-use terminal is shared.

Hardware
Nest is compatible with most standard HVAC systems that use central heating and cooling and use industry standard connections to facilitate control of this equipment.
Nest is not compatible with HVAC systems that communicate. The communication system is used with several two-stage HVAC systems and all variable capacities. This system requires only four cables - two power cords for heating and cooling and two for communication between components (see photo).
Nest consists of two main parts of hardware. The display contains the main printed circuit board (PCB) and the rotating ring, and the base (picture) houses the connection terminal, bubble level, and hole for wall support. Can not function independently; if separated, the screen becomes inactive until it is reconnected to the base.
A special version of Nest is available in Europe, capable of controlling the 230 volt heating system. The Nest is paired with the "Heat Link" device, which contains the circuitry needed to control the electrical voltage heating system. The first release is the 2nd Generation Nest thermostat that Heat Link controls the central heating boiler. The 3rd generation adds support for OpenTherm and for controlling domestic hot water.
The Nest Temperature Sensor was added in March 2018. Up to six of these battery-operated devices can be added to a thermostat to provide remote temperature monitoring. Nest will then use appropriate sensors based on schedule. Because they use Bluetooth Low Energy, they are only compatible with thermostat E and third generation.
Software
The Nest Thermostat is built around an operating system that allows interaction with the thermostat through spinning and controlling the control wheel, which presents an option menu to switch from heating to cooling, access to device settings, energy history, and scheduling. Users can control Nest without touch screen or other input devices. Because 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 cost of 3.7 V to provide enough power to complete downloading and installing updates.
The Nest Thermostat already has a number of software updates. Recent security updates allow two-factor authentication.
Many have commented on the company's "Nest Community" about the lack of prominent display of current temperatures.
The operating system itself is based on Linux 2.6.37 and many other free software components. To comply with the GPLv3 licensing terms in which several components are available, Nest Labs also provides a special firmware image that will unlock the system so it will receive an unsigned firmware image.
While the Thermostat software by Nest Labs itself remains proprietary, third parties have applied basic logic in open source replacement called FreeAbode.
Nest devices are connected to each other using a protocol called Weave, 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, England, Belgium, France, Ireland, Netherlands, Germany, Austria, Italy, and Spain. Nevertheless, it is compatible with many heating and cooling automation systems in other countries. Nest Labs has surveyed existing users who are known to be outside the area that is officially available. The use of thermostats outside the United States and Canada is complicated by the timing of software settings and other functions based on zip codes. For international users, this means they must disable Wi-Fi to set the time correctly or use the nearest US postal code that may lead to erratic behavior because the thermostat makes the wrong assumption about a good inactivity when sleeping or the occupants of the house are on the go.
In 2013, man-in-the-middle hack could potentially allow users around the world to set their local time zones and weather.
In an effort to increase the number of homes using their learning thermostats, Nest began partnering with energy companies. In February 2014, the Direct and Nest Energy laboratory launched their Convenience and Control plan. The plan allows Canadian customers in Alberta to receive a learning thermostat when they sign up for a five-year electric contract. In April 2014, Nest announced a partnership with nPower UK energy supplier. This partnership offers Nest Nest customer price discounts and locks energy prices for 5 years, when customers receive gas and electricity from nPower and pay by direct debit.
In June 2014, Direct Energy and Nest Laboratories expanded the package to the US market of Direct Energy.
