Home automation systems integrate electrical devices in a house with each other. The techniques employed in home automation include those in building automation as well as the control of domestic activities, such as home entertainment systems, changing the ambiance "scenes" for different events (such as dinners or parties), CCTV and Security Systems. Devices may be connected through a computer network to allow control by a computer, smart phone, tablet PC (such as an iPad), and may allow remote access from the internet.
Through the integration of information technologies with the home environment, systems and appliances are able to communicate in an integrated manner which results in convenience, energy efficiency, and safety benefits.
Home automation technologies are viewed as integral additions to the Smart grid. The ability to control lighting, appliances, HVAC as well as Smart Grid applications (load shedding, demand response, real-time power usage and price reporting) will become vital as Smart Grid initiatives are rolled out.
Controlling your Home
In simple installations, automation may be as straightforward as turning on the lights when a person enters the room. In advanced installations, rooms can sense not only the presence of a person inside but know who that person is and perhaps set appropriate lighting, temperature, music levels or television channels, taking into account the day of the week, the time of day, and other factors.
Green Automation is the term coined to describe energy management strategies in home automation when data from smart grids is combined with home automation systems to use resources at either their lowest prices or highest availability, taking advantage, for instance, of high solar panel output in the middle of the day to automatically run washing machines.
