Title: CONTROL DEVICE, APPARATUS FOR USE IN A LUMINAIRE, METHODS OF OPERATION AND SERVER
Abstract:
A control device (2) for wirelessly communicating with a luminaire (1) is arranged to identify a luminaire (1) by receiving from the luminaire (1) a unique identifier for the luminaire (1). A time-bound key for the identified luminaire (1) is stored. The time-bound key is generated from a device key for the luminaire (1) and a time slot for which the time-bound key may validly be used. The control device (2) is arranged to generate a predetermined message that is encrypted using the time-bound key and to wirelessly transmit the encrypted predetermined message to the luminaire (1).
