In one embodiment, device addition to an expandable multimedia control system is performed without creating or modifying source code. A configuration bundle is stored on a first device of the expandable multimedia control system, the configuration bundle including a list of unique identifiers (UIDs) representing devices that are eligible to become a part of the expandable multimedia control system. The first device monitors a local area network (LAN), and determines a UID of a second device. The first device compares the UID of the second device with the list of UIDs in the configuration bundle. In response to a match of the UID of the second device with a UID of the list of UIDs in the configuration bundle, the second device is added to the expandable multimedia control system, and at least a portion of the configuration bundle is shared with it.
