Energy Management
Home automation controllers base the use of electricity on your lifestyle and needs. If you only need a light on in the living room when you are home and it is night, the controller can be programmed to observe that the home is occupied and it is night so it will turn on the light. If the room is unoccupied for a period of time the system can be set-up to turn off the light. These simple instructions can reduce electrical usage by up to 5%. Not a cost justification, but a start.
