Devices Registered with the IoT Platform Are Deleted After a Period of Time
When a device is registered by calling an API, the timeout parameter must be configured. After the registration is complete, if the device is not bound to the IoT platform within the time specified by timeout, the IoT platform will delete the device.
The value range of timeout is 0-2147483647, which is measured in units of seconds. When this parameter is set to 0, the device is permanently valid and will not be deleted.
