Claim Text:
1. A switch module for use in a lighting system, the switch module comprising: a sensor, including circuitry, configured and arranged for sensing control operation of the switch module by a user; a transceiver for transmitting and receiving messages via a communication medium; a memory for storing an ID information value; and a processing circuit coupled to the sensor, the transceiver and the memory, and configured to cause the transceiver to transmit lamp control messages comprising ID information derived from the ID information value in the memory, in response to sensing of the user control operation by the sensor, the processing circuit being furthermore configured to detect reception, by the transceiver, of a message reporting user control operation of a further sensor of a further switch module, the message including ID information of the further switch module, wherein the processing circuit is configured to determine whether a time interval between a user control operation of the one sensor of the switch module and a time point associated with said message reporting the user control operation has a duration below a threshold, and to cause the ID information value in the memories of the switch module and the further switch module from which the ID information in the message is derived to acquire matching values when said duration lies below the threshold, wherein the matching values are derived based on the ID information of the switch module and the ID information of the further switch module.
