1. A control device for controlling at least one wirelessly connected lighting device within a wireless network, wherein the control device comprises:
a transceiver configured to overhear and transmit a message within the wireless network;
a light sensor configured to detect a light signal comprising a temporal characteristic that is characteristic for an first artificial light source;
a processor operatively coupled to the light sensor and the transceiver, wherein the processor is configured to:
determine, based on analyzing said temporal characteristic, a first condition that the light signal belongs to the first artificial light source, and
wherein the processor is configured to:
determine, by overhearing the wireless network with the transceiver, a second condition that no control message is transmitted within the wireless network within a time period prior to the moment of detecting said light signal, and
transmit a control message to the at least one wirelessly connected lighting device upon determining said first condition and said second condition.
