IoT Platform supports the monitoring of the network status. A device that accesses the network through Wi-Fi can report the network status to IoT Platform through a specified topic. On the Real-time Monitoring page of the console, you can select the Device Network Status tab to view the Wi-Fi signal quality of the device.
For more information about the topic, data format, and errors of device network status messages, see Device network status.
If your devices use AliOS Things 3.0 or later, the system automatically monitors and reports network status data. For more information about network errors, see the err_stats table in Device network status.
