Abstract

A power distribution system/method implementing Internet based access to hybrid home automation networks is disclosed. The system utilizes a smart gateway power controller (SGPC) configured for single/multi-gang wallplate installation to selectively switch an AC power source to a load device under switched control and/or local/remote network commands that may be routed through a variety of network interfaces and protocols present within a home or other structure-local communications network. SGPC configurations may be nested within a home automation network to permit separation of control for load devices within a common home automation environment. Present invention methods may include routing protocols between disparate home automation networks as well as remote access protocols that permit control of disparate home automation networks via the Internet using a wide variety of remote access interfaces including mobile devices, tablet computers, laptops, desktop computers, and the like.
