Home automation technology allows users to control home appliances like lights, fans, entertainment systems, and security systems remotely using a WiFi connection and sensors. This helps save energy by automatically turning devices off when not in use. Sensors can detect users' presence and customize settings like lighting and music. The system also enables remote control of heating, ventilation, and air conditioning. Users need an internet connection, sensors, and a web-enabled device to access the automation system and control appliances both inside and outside the home.
