Abstract

A home automation and control architecture that includes one or more controlled devices and one or more control panels coupled by a communication network. Each of the controlled devices is directly coupled to at least one control panel and configured to communicate control information with the coupled panel. The control panels comprise sufficient computing resources for implementing a user interface and executing application software to generate control messages based on user input and/or context information of which the control panel is aware. A message broker implemented within the pone or more control panels conveys control messages from a first control panel that initiates the control message to one or more other control panels that implement the control message. An inter-control communication path couples each of the control panels such that any one of the control panels can effect control over any of the controlled devices by communicating through another control panel that is directly coupled to a specific device.

Claims

processes implemented within the plurality of control panels operable to generate command messages relevant to at least one of the controlled devices; and

processes implemented within the plurality of control panels operable to handle status messages relevant to at least one of the controlled devices.

2. The home automation control system of claim 1 wherein at least one controlled device is directly coupled to one of the plurality of control panels.

3. The home automation control system of claim 1 further comprising a process executing in at least one of the plurality of control panels operable to receive a message from the packet communication network, interpret the message.

4. The home automation control system of claim 1 wherein at least one of the plurality of controlled devices comprises a subsystem that implements a device specify signaling protocol with one or more other controlled devices.

5. The home automation control system of claim 1 wherein the plurality of control panels implement a plug-in framework that enables addition of plug-in software modules to define functionality.

6. The automation control system of claim 1 wherein the plurality of control panels each implement a set of plug-in software components independently of a set of plug-in software components implemented in any other of the control panels.

7. The home automation control system of claim 7 wherein the plug-in framework comprises a web server to support a web browser graphical user interface.

8. The home automation control system of claim 7 wherein the framework provides interfaces to hardware platform drivers accessing hardware features of the control panel.
