In order to solve the problem on how to connect a smart device to the platforms of different cloud service providers, the invention provides a smart component for smart home appliances, a smart home appliance, a smart home appliance system and a method thereof. The smart component comprises a controller used for defining a queue data structure, writing status parameters and/or environmental parameters sensed by a sensor in the smart home appliance into the queue data structure in chronological order and creating a process and a socket for each of one or more cloud platforms, and a communication module used for transmitting the status parameters and/or environmental parameters written in the queue data structure to the one or more cloud platforms in parallel by using the processes and the sockets created by the controller. By adopting the smart component, the smart home appliance, the smart home appliance system and the method thereof provided by the invention, the problem on how to connect a smart device to the platforms of different cloud service providers can be solved.
