A control device (3) for controlling a lighting system (19) over a communication system comprising one or more networks, the lighting system comprising at least one lighting device (1a, 1b, 1c). The control device comprises: multiple transmitters (4a, 4b, 4c, 4d, 4e) each for transmitting to the lighting system via a different respective interface (7a, 7b, 16, 17, 51) of the communication system; A and a controller (95) configured to use each of a plurality of the transmitters to transmit a respective message to the lighting system via a different respective path, each path comprising a different respective one of the interfaces and not Bluetooth RFID tag Wi-Fi ZigBee Cellular any of the others. Each of the messages invokes feedback from the lighting system to the control device if received and/or if executed by the lighting system. The controller compare the paths in dependence on the feedback, and based thereon to select which of the interfaces to use to transmit subsequent lighting control commands to the lighting system for controlling the lighting system.
