Abstract: A second communication unit of a wireless controller transmits a first signal to luminaires, the first signal instructing the luminaires to respond to a request from the wireless controller. A control unit (i) receives a response to the first signal sent from the luminaires, (ii) when there is a first group including a luminaire that has responded to the first signal, and a second group including at least one luminaire that has not responded to the first signal, assigns the luminaire in the first group as a relay luminaire, and (iii) transmit a second signal to the relay luminaire, the second signal instructing the relay luminaire to wirelessly communicate with the at least one luminaire in the second group via the second communication unit. The relay luminaire that has received the second signal wirelessly communicates with the at least one luminaire in the second group via a first communication unit.
