Network distribution method and device of multi-split air conditioner, multi-split air conditioner and storage medium

The invention relates to a network distribution method and device of a multi-split air conditioner, the multi-split air conditioner and a storage medium, and the method comprises the steps: when it is determined that the multi-split air conditioner enters a one-key network distribution mode, an outdoor unit sends a routing detection instruction to at least one wire controller, so that the at least one wire controller carries out the routing detection in response to the routing detection instruction to obtain available WiFi, and the WiFi is used for carrying out the network distribution of the multi-split air conditioner; and according to the available WiFi returned by the at least one wire controller, obtaining the WiFi password corresponding to the available WiFi, and sending the WiFi password to the at least one wire controller, so that the at least one wire controller is connected to the router based on the available WiFi and the WiFi password, thereby realizing one-key network distribution of the multi-split air conditioner, realizing synchronous network distribution of the at least one wire controller of the multi-split air conditioner, and improving the network distribution efficiency of the multi-split air conditioner. Therefore, the network distribution of the wire controller is simpler and more convenient, and the network distribution efficiency is improved.
