Power line communication-based pairing method and device for air conditioner, and storage medium

An indoor unit of an air conditioner, comprising:

• a Central Coordinator (CCO) module, coupled and connected to a power line network, and configured to:
• select a to-be-paired station (STA) module in the power line network as a pairing object based on a pairing request instruction;
• send pairing request information to the power line network, the pairing request information comprising the pairing request instruction, identifier (ID) information of the CCO module and ID information of the pairing object;
• receive pairing feedback information from a STA module of an outdoor unit based on the power line network, the pairing feedback information comprising a pairing success instruction, the ID information of the CCO module and ID information of the STA module;
• and
• determine that pairing is successful in response to determining that the ID information of the CCO module exists in the pairing feedback information, and establish a pairing relationship with the STA module.
