A method and an apparatus for updating a gateway resource, and an Internet of Things (IoT) control platform, which belong to the field of IoT. The method is applicable to the IoT control platform connected to each gateway device, and the gateway device is connected to an IoT device. The method includes: acquiring a model change message including a change model identifier of a changed model, wherein different IoT devices correspond to different models, and each model contains measuring point information of a measuring point in the IoT device; determining an associated template based on the change model identifier and updating the associated template, the associated template containing a corresponding relationship between the measuring point information and a measuring point identifier in the changed model, and the measuring point identifier being applicable to a measuring point data message sent by the IoT device; determining a target gateway device that uses the associated template; and issuing a gateway resource update package to the target gateway device, the target gateway device being configured to update the gateway resource based on the gateway resource update package.
