Energy management gateway and method thereof

The present invention relates to a method of an energy management gateway (101) being associated with an electricity meter (103) and with a plurality of electricity outlet sockets (102). The method comprises detecting a pattern (402) of consumption of electricity originating from one of the outlet sockets by means of the electricity meter; identifying the outlet socket from which the pattern originates; determining that the detected pattern fulfils a criterion, whereby the pattern is recognised as a pattern formed by an association device (401) connected to said outlet socket; outputting via a user interface an indication that the identified outlet socket is ready to be associated with an electrical load type; receiving via the user interface an indication about with which electrical load type the identified outlet socket should be associated; and associating the identified outlet socket with the load type in accordance with the received indication.
