Electroacoustical speaker devices that synchronously play audio received from a source. In one embodiment, one speaker acts as the master and the other speaker acts as the slave. The master speaker receives digital audio data from a source and, in addition to playing the digital audio received from the source, the master speaker retransmits the digital audio to the slave speaker. The master speaker additionally sends synchronization data to the slave speaker, such as data that indicates the buffer status or playback position of the master speaker. The slave speaker utilizes the synchronization data from the master speaker to adjust, for example, its buffer status or playback position, so that the two speakers play the audio synchronously (e.g., within thirty milliseconds). In one embodiment, the master speaker uses a connection-oriented protocol, such as TCP/IP, to transmit buffered audio data to the slave speaker and uses a connectionless protocol, such as UDP or ICMP, for the synchronization data. In addition, the speakers may transition roles as master and slave.

A home automation protocol system provides a network consisting of a number of node devices, controllers, and servers for storing information about node device settings and scene settings in a home environment is provided. The node devices are controlled by the controllers, in that the node devices are set to create scenes, which are stored in a scene server, while the operational states of the node devices are stored in a status server. The status server and scene server may be provided as separate units. The home automation protocol network is controlled by sending commands to the devices and servers, and new devices and controllers are added or updated, and new scenes are programmed. The network protocol allows devices running different protocols to be incorporated into the network.
