A protocol for controlling lighting devices within a network enables bidirectional communication between different connected devices, any of which may function as a server, a device, a broker, or multiple of these roles. Upon initialization of the network, a server device requests a basic configuration data file from each device on the network and, thereafter, requests a more extensive configuration data file identifying capabilities and functionalities of the device which the manufacturer has made discoverable. Each device sends its basic configuration file to the server device upon any of power on, reboot, reset, hardware configuration change, or software change to the respective device. A device on the network can also be a collection of sub-devices each of which may be separately identified, and their respective capabilities evaluated, so that the server can separately control either the device or any of the individual sub-devices.
