1. A control device for controlling a plurality of lighting devices via a network, the control device comprising:a receiver for receiving a signal based on a user input related to adjusting a control parameter of the plurality of lighting devices,
a processor for generating, based on the received signal and on a predetermined network capacity, one of: a plurality of messages of a first type and a single message of a second type, and
a transmitter for transmitting the plurality of messages of the first type if the plurality of messages of the first type are generated, or the single message of the second type if the single message of the second type is generated, via the network, thereby adjusting the control parameter of the plurality of lighting devices,
wherein the processor is further arranged for determining network utilization relative to the predetermined network capacity,
wherein the generation of the one of: the plurality of messages of the first type and the single message of the second type is further based on the network utilization and on a characteristic of the user input, which characteristic is related to a number of user input commands received within a predetermined time period, and
wherein the message of the first type is a unicast message addressed to a single lighting device of the plurality of lighting devices and wherein the message of the second type is a multicast message addressed to the plurality of lighting devices.
