A lighting system includes a system controller, at least one light fixture, and at least one non-fixture system device. The system controller initiates automated commissioning by instructing a light fixture of the lighting system to modulate light output by the light fixture with a commissioning code. At least one system device of the lighting system receives the modulated light output and demodulates the received light output to determine the commissioning code. In response to determining the commissioning code, the at least one system device sends an acknowledgment message to the system controller. The system controller associates the system devices sending an acknowledgment message with the light fixture providing the light output modulated with the commissioning code.
