Home automation is automation of the home, housework or household activity. Home automation may include centralized control of lighting, HVAC (heating, ventilation and air conditioning), appliances, and other systems, to provide improved convenience, comfort, energy efficiency and security. Home automation for the elderly or disabled can provide increased quality of life for persons who might otherwise require caregivers or institutional care.
A home automation system integrates all electrical devices in a house with each other. Typically, a new home is outfitted for home automation during construction, due to the accessibility of the walls, outlets, and storage rooms, and the ability to make design changes specifically to accommodate certain technologies. These Smart home technologies communicate through existing power wiring, radio, or infrared signals with a central controller.
