A "smart home" refers to a residence equipped with devices that can be controlled remotely through a smartphone or computer. These devices often include smart lights, thermostats, security cameras, and smart speakers, allowing homeowners to manage their environment easily and efficiently. The technology behind smart homes typically involves Internet of Things (IoT) devices that communicate with each other and can be programmed for automation. This means you can set your smart thermostat to adjust the temperature when you leave or arrive home, enhancing comfort and energy savings.
