Abstract: The invention relates to a luminaire (1d) connected to a plurality of further luminaires (1a-c, 2a-e) allocated to at least one group via a network. In order to detect and correct a de-synchronization, the luminaire (1d) is configured to (i) receive a status message from each of the further luminaires (1a-c, 2a-e), each status message including status information indicating a current status of the respective luminaire (1a-c; 2a-e) and trigger information about a trigger that prompted the respective luminaire (1a-c; 2a-e) to adopt the current status, (ii) select at least some of the received status messages based on the trigger information included therein, and (iii) compare the selected status messages and change its own status to a new status based on the comparison. Further, the invention is related to a corresponding method for changing the status of the luminaire (1d).
