How Is the Status of a Device Changed?
An NB-IoT device is considered online when it reports data to the IoT platform. If no data is reported within 25 hours since the last data reporting, the device status changes to abnormal. If no data is reported within 49 hours, the device status changes to offline.
An MQTT device is considered online when it is connected to the platform. If the device is disconnected from the platform, it is considered to be offline and its status will be updated on the platform within a minute. You can click the status refresh button to update the status immediately.
