Method and system for controlling home appliance

A server device comprising:

• a communication interface configured to communicate with at least one home appliance;
• at least one processor;
• and
• a memory storing one or more instructions that, when executed by the at least one processor, cause the server device to perform:
• an operation of receiving a first instruction packet of a first group device, which is connected to a home network hub device and controlled by the first instruction packet broadcast from the home network hub device, from a relay device connected to the home network hub device;
• an operation of storing the first instruction packet;
• an operation of identifying, based on first environment information obtained from the first group device or a second group device, a first scenario corresponding to the first environment information among a scenario list defining at least one operation of at least one of the first group device or the second group device;
• an operation of identifying, based on the first scenario, at least one of the first instruction packet for controlling an operation of the first group device or a second instruction packet for controlling an operation of the second group device;
• and
• an operation of transmitting the first instruction packet to the relay device connected to the home network hub device and transmitting the second instruction packet to the second group device,
• wherein the at least one home appliance includes at least one of the second group device or the relay device.

A relay device comprising:

• a first standard communication interface configured to communicate with a home network hub device;
• a second standard communication interface configured to communicate with a server device;
• at least one processor;
• and
• a memory storing one or more instructions that, when executed by the at least one processor, cause the relay device to perform:
• an operation of receiving a first instruction packet for controlling an operation of a first group device, which is broadcast from the home network hub device, through the first standard communication interface,
• an operation of transmitting the received first instruction packet from the home network hub device to the server device through the second standard communication interface to store the first instruction packet in the server device,
• an operation of receiving the first instruction packet from the server device through the second standard communication interface, and
• an operation of transmitting the received first instruction packet from the server device to the home network hub device through the first standard communication interface.
