1. A luminaire connectable to a plurality of further luminaires allocated to at least one group via a network, the luminaire being configured to:
receive a status message from each of the further luminaires, each status message including:
status information indicating a current status, comprising a current light level, of the respective luminaire, and
trigger information about a trigger that prompted the respective luminaire to adopt the current status, wherein the trigger information is indicative of whether the trigger relates to all luminaires of a group or is only valid for the respective luminaire,
select at least some of the received status messages that include trigger information indicative of a trigger relating to all luminaires of the allocated group and which do not include trigger information indicative of a trigger that is only valid for the luminaire having sent the respective status messages,
compare the current light level of each of the respective luminaires as indicated in the selected status messages to each other and to the light level of the luminaire itself,
check whether a number of the selected status messages, which is greater than a predetermined threshold, include identical status information and/or corresponding trigger information corresponding to each other, and
change the light level of the luminaire to a light level selected in accordance with this status information or trigger information if the check is affirmative.
