Abstract
Lights may be misconfigured during installation or after they are installed in a facility, such that these lights, also known as orphaned nodes, cannot receive control messages sent by a lighting control system. After installation, a mobile device can be used to identify the network a particular light source is communicating on, by use of a photodetector that detects, in the visible light signal emitted by a light source, data representing the network ID used by the light source. The mobile device can determine from that data whether or not the light source is communicating over the wrong network. If it is determined that a light source is on the wrong network, and therefore orphaned, the mobile device can switch its own configuration so as to be able to communicate to the orphaned light source, and provide instructions to reconfigure the light source to use a corrected network ID.
