Abstract

A method (20) for functional classification of luminaires (101a-d) arranged as a grid (100) has luminaires (101a-d) with at least two different sensors (103, 105, 107), such as at least two of a light sensor (103), an acoustic sensor (105) and a motion sensor (107). Output signals of the sensors (103, 105, 107) are supplied to a controller (109), and are wirelessly forwarded (23) along with timestamps and luminaire IDs to a gateway and then transmitted to a central database (403). The timestamps are used to correlate the sensor information signals (130) over a defined period of time, and to generate (27) functional classification information based on the correlations found. The functional classification information indicates a likelihood function of a certain usage of each luminaire, out of a given set of usage functions.
