The invention discloses a method and a device for pairing lighting equipment and switches without wires in the IoT (Internet of Things). The method comprises the following steps: each Wi-Fi (wireless fidelity) switch receives corresponding information packets from different sets of Wi-Fi lighting equipment wirelessly, and a user determines to-be-paired equipment from the multiple sets of Wi-Fi lighting equipment to realize pairing through sending of a flicker instruction corresponding to the MAC (medium access control) address of the Wi-Fi lighting equipment. Connections in different forms such as one to one, one to many, many to many and the like between the wireless switches and the lighting equipment can be realized. An additional control circuit is no needed during wiring of the lighting equipment, and use of copper wires is reduced greatly. Meanwhile, the user can change the pairing form of the lighting equipment and the switches conveniently and flexibly according to requirements.
