The present invention defines a HTTP or CoAP request message that combines one or more HTTP or CoAP requests along with timing information (432-1). The message is sent by a control device (132) to a network proxy (i.e. a network router (112)) via a control network (120). The network proxy decodes the message and subsequently controls destination devices, in particular luminaires (L1, L2, L3, L4), in a timed manner using the HTTP or CoAP requests. The network proxy is application-independent and also enables control of third party HTTP-or CoAP-based devices that are not aware of timed requests. Improved timing performance is obtained by choosing the network proxy location “close by”, in terms of network hops and/or latency, to the destination devices to be controlled. |

1. A method of controlling a lighting system, the lighting system comprising a number of luminaires, a network router configured to be coupled to the number of luminaires and a control device configured to be coupled to the network router via a control network, the method comprising:
providing, by the control device, a control message, the control message including timing information and command information; receiving, by the network router, the control message via the control network; generating, by the network router, a command in dependence on the command information; determining, by the network router, in dependence on the timing information, a first point in time for forwarding the command to at least one of the number of luminaires identified in the control message; and forwarding, by the network router, at the determined first point in time the command to the at least one of the number of luminaires identified in the control message. |
