Power supply control method based on Wi-Fi (wireless fidelity) and Wi-Fi power socket

The invention provides a power supply control method based on Wi-Fi (wireless fidelity) and a Wi-Fi power socket. The method comprises the following steps of: utilizing a Wi-Fi module built in the power socket to receive a control command sent by Wi-Fi control equipment; and utilizing a relay to operate and control the on and the off of the power socket according to the control command. The Wi-Fi power socket can comprise the Wi-Fi module, wherein the Wi-Fi module is built in the power socket and is used for receiving the control command sent by the Wi-Fi control equipment; and the relay is utilized to operate and control the on and the off of the power socket according to the control command. The Wi-Fi power socket is provided for a household appliance, so that household appliances control taking the Wi-Fi control equipment as a center can be simply realized; the inter-connection and the inter-operation between the Wi-Fi power socket and the Wi-Fi control equipment can be realized directly without AP (Assemb
