A Wi-Fi home thermostat is a control unit of a heating or cooling system that can be operated via a wireless network. Its control panel can be accessed via a Web browser or app on supported Wi-Fi-enabled devices to maintain the desired temperature in the home.
Depending on the model, a Wi-Fi home thermostat may offer smart features not found in a traditional, manually controlled thermostat. For instance, it may be programmable to change the temperature based on the time of day. A "smart" thermostat may also provide energy consumption details, adjust room temperature based on user behavior or activity, and employ sensors for other factors that affect room ambiance, such as humidity and lighting.
