• receiving, by a processor, a feature command for a first home appliance from the first home appliance or a second home appliance;
• generating, by the processor, a prompt including the feature command and configuration information of the first home appliance;
• providing the prompt to an artificial intelligence (AI) theme module to generate a result;
• and
• converting the result into a first feature set for changing the feature of the first home appliance based on the first feature set.

A non-transitory computer readable medium storing computer-executable instructions that when executed by a processor, cause the processor to perform the operations of:

• receiving a feature command for changing a feature of a home appliance;
• determining whether the feature command matches a first feature set stored in a database;
• in response to failing to match the feature command to the first feature set, providing the feature command to an artificial intelligence (AI) theme module to generate a second feature set;
• in response to the AI theme module failing to generate the second feature set, generating a third feature set based on personalized user information;
• and
• changing the feature of the home appliance to correspond to one of the first feature set, the second feature set, or the third feature set.
