1. A lighting control device installed in a space, the lighting control device comprising:
one or more communications circuits, wherein at least one of the one or more communications circuits is configured to receive beacon messages from a tracked device, and wherein at least one of the one or more communications circuits is configured to receive digital messages on a wireless communication network; and
a control circuit configured to:
receive, via the one or more communication circuits, the digital messages configured to control a corresponding electrical load;
control the corresponding electrical load in response to the digital messages;
receive, via the one or more communication circuits, the beacon messages from the tracked device in the space, each of the beacon messages comprising a beacon identifier for the tracked device;
measure a communication quality metric of each of the beacon messages;
process the communication quality metric of each of the beacon messages over a period of time to generate a processed communication quality metric associated with the tracked device;
detect a change in the processed communication quality metric associated with the tracked device; and
in response to detecting the change in the processed communication quality metric, transmit tracking data, wherein the tracking data includes the beacon identifier of the tracked device and the processed communication quality metric associated with the tracked device.
