Control method of smart home equipment, smart home system and gateway thereof

The invention discloses a smart home device control method, a smart home system and a gateway thereof. The system comprises a cloud server, a plurality of smart home devices and a plurality of gateways. a master gateway and a plurality of slave gateways are configured; the master gateway receives the scene ID sent by the cloud server and sends the scene ID to the slave gatewasy; and each gateway determines an operation to be executed by the smart home device connected with the gateway according to the scene ID, and sends a control instruction to the smart home device connected with the gateway. A distributed gateway system is adopted, the cloud server only needs to send the scene ID to the main gateway, the occupied server bandwidth during scene control is effectively reduced, the main gateway sends the scene ID to all the slave gateways, and all the gateways execute the scene ID according to the stored scene ID and the operation needing to be executed by the scene ID corresponding tothe intelligent home equi
