FIELD: lighting.
SUBSTANCE: set a message with an HTTP or CoAP request that combines one or more HTTP or CoAP requests with time synchronization information. The message is sent by the control unit (132) to the network proxy (i.e. the network router (112)) via the control network (120). The network proxy decodes the message and then controls the destination devices, in particular lighting devices (L1, L2, L3, L4), with time synchronization using HTTP or CoAP requests. A network proxy is application-independent and also provides control of third-party HTTP or CoAP-based devices that do not have information regarding time synchronized requests. Increased time synchronization performance is obtained by selecting the location of the network proxy "next", in terms of network hopping and/or latency, with the destination devices to be controlled.
EFFECT: providing the possibility of accurate and reliable control of the lighting system according to time synchronization, which can easily be implemented in the existing lighting system without the need for a new network protocol.
