A method of automatically commissioning a lighting system comprising a plurality of luminaires for illuminating one or more regions within a space. The method comprises: receiving signals from a positioning system, indicating a respective location within the space at which each of a plurality of physical entities is detected by the positioning system, each of the entities being a person or a movable nonhuman object. The method further comprises determining a spatial distribution of at least some of the entities based on the locations indicated by the signals from the positioning system, and determining a region within the space corresponding to this spatial distribution. The method then comprises identifying a group of the luminaires that are arranged to illuminate the determined region and storing identifiers of those luminaires together as a group in a commissioning database.
