    Abstract: The invention relates to a method for managing light settings of a luminaire communicatively connected to a local coordinator. The method, performed by the luminaire, includes steps of providing to the local coordinator a control state of the luminaire (e.g. occupancy status), receiving from the local coordinator a power reduction factor for the luminaire, the factor being based on the control state of the luminaire and on control states provided to the local coordinator by one or more additional luminaires, determining new illuminance settings for the luminaire by applying the received factor to current illuminance settings, measuring luminance within a sensing region of a light sensor of the luminaire while one or more light sources of the luminaire emit light according to one or more operating parameters, and, based on the measured luminance, adjusting the operating parameters to achieve the new illuminance settings.

    Abstract: The disclosure relates to a lighting system which can be controlled from a wireless device in dependence on complying with an access rule that the wireless device is determined to be within in a spatial region associated with the lighting system. The disclosure provides apparatus for securing against the lighting system being controlled from a device located outside the relevant region via a rogue relay device located in that region. The apparatus comprises a user location module configured to determine user location information indicative of whether a user is accompanying the wireless device in the region associated with the lighting system, and an access module which is configured with a further access rule: that it does not allow the control of the lighting system by the wireless device if the user location information is indicative of the wireless device being unaccompanied by a user.
