A system (1) is configured to receive device control information. The device control information specifies how devices, e.g. lights, should be controlled. The device control information may identify specific devices or specify device requirements, for example. The system is further configured to form a group of identified devices by analyzing the device control information, the identified devices of the group being controlled similarly according to the device control information. The system is also configured to transmit at least one message comprising an identifier of the group to allow the identified devices to be configured to carry out one or more commands comprising the identifier when receiving such one or more commands. The at least one message identifies the identified devices of the group.
