Patent number: 6823223Abstract: A method and apparatus for providing a simple user interface for programming scenes and multi-way groups in a home automation and control system is provided. Each device participating in the home automation and control system is equipped with control logic for providing the simple programming interface. Through the control logic, each device maintains its status in a system-wide programming mode and retains knowledge of its inclusion or exclusion in the current scene or multi-way group being programmed. When any device in the system receives indications that affect the system programming mode, such as a press on one of the buttons on the devices, the device broadcasts a notification message to all devices within the home automation and control system. The message maintains the integrity of the system programming mode. Each device knows when a scene or multi-way group being programmed is finally captured and the programming of a new scene or multi-way group has started.Type: GrantFiled: May 22, 2002Date of Patent: November 23, 2004Assignee: Microsoft CorporationInventors: Greg Gonzales, Brian D.
