For automated commissioning for automatic grid mapping, load devices comprising a load and detection devices have the detection devices (1) communicate with management devices (2) and comprise detectors (11) for detecting switchings of loads (3), timers (12) for determining and storing timings of the switchings of the loads (3) and transmitters (12) for transmitting information to the management devices (2). This information defines the timings of the switchings of the loads (3) as well as identifications of the detection devices (1), of the loads (3), and/or of load devices (201-220) comprising the detection devices (1) and the loads (3). The timings of the switchings of the loads (3) may define moments in time. By switching different groups of loads (3) at different moments in time, the different groups can be distinguished from each other. The management devices (2) comprise receivers (21) configured to receive the information from the detection devices (1) and may further comprise controllers (22) for controlling the switchings of the loads (3) to take place at different moments in time.
