Abstract

A control communication network system adapted for distributed control and communication between various home electrical appliances in a manner that eliminates the need for a central controller and eliminates or greatly simplifies the manual assignment of addresses, control relationships or other network resources. The system utilizes a novel and useful process of "hailing" for addresses or resources by newly introduced network devices combined with a process by which declaratory statements are used to convey identification or resource availability information to potential controlling devices. The present invention comprises an intelligent lightswitch which can be dynamically "taught" to control or to be controlled by any other similar lightswitch in a given house without special wiring or user intervention other than the toggling of a simple "teach/learn" switch associated with each lightswitch.
