Scene linkage synchronization method and system

The invention relates to a scene linkage synchronization method and system, and the method comprises the steps: generating a corresponding unique theme according to the association information of a device when the device needing to be associated with other devices accesses the network; sending the information of the generated theme to the associated equipment according to the associated information, so that the associated equipment subscribes to the theme; when the state of the equipment participating in the linkage changes, issuing an equipment state change message on the corresponding theme, and sending the equipment state change message to equipment subscribing to the same theme as the equipment with the changed state through the MQTT service; the equipment receiving the state change message performs corresponding state updating; by applying the method provided by the invention, when the state of one device is changed, the associated device can quickly change the corresponding state through the MQTT servic
