Abstract:
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.
Abstract:
A method and apparatus for providing distributed control of a home automation and control system is provided. Each device participating in a home automation and control system is equipped with control logic for providing distributed control. Through the control logic, each device maintains scene definitions describing the state of the device for each scene in which it participates. When any device in the system receives a request to launch a scene, such as a button press on one of the devices, the device broadcasts a scene state change message to all devices within the home automation and control system. The scene state change message identifies to each device that a particular scene that should be launched. Each device in the system receives the message and determines whether the device is a participant in the scene. If the device is a participant in the scene, the device adjusts its state according to a scene definition stored in the device associated with the scene. The device may adjust a controlled electrical load, such as a light, according to the scene definition by turning the load on, off, or setting the load to some intermediate value. If the device is a not participant in the scene, the device remains unaffected.
