The author describes an enabling system called SMART HOUSE that provides the common resources needed for home automation in a multiproduct, multivendor environment. The system includes the following: a system controller, housewide wiring network, communications protocols, standard interfaces (outlet designs) for connecting other products, and basic user controls such as programmable wall switches and DTMF telephone. Providing complete home automation functionality depends on the addition of other products such as more complex user controls, appliances that include consumer electronics, and application-specific controllers for energy management, security, climate control, etc. These compatible appliances and controllers are equipped with proprietary communications circuits that permit them to communicate with the system controller and with each other. The author provides a concise technical description of the system, concentrating upon the control communications aspects, including system architecture, protocols, messaging, and logic structure
