Wall-Mounted Smart Switches and Outlets for Use in Building Wiring for Load Control, Home Automation, and/or Security Purposes

摘要

Nodes installed at various locations throughout a building each include a wall-mounted unit supported by an in-wall electrical box, a connection inside said in-wall electrical box between the wall-mounted unit and said mains-power wiring system of the building, and a power line communications transceiver by which the nodes can communicate through said connection to the mains-power wiring system, and at least sensor operable to detect home intrusion events. Each node is configured to, in response to a detection of a home intrusion event by said node, activate a local alarm-responsive action at said node that detected the home intrusion event, and also send out an alarm signal for triggering additional alarm-responsive actions at the other nodes. The sensor(s) include a microphone operable to capture audible events, through which the node can recognize home intrusions events and verbal commands for voice-activated functions, and perform alarm-related or control-related functions accordingly.
