This topic describes how to delete a device in the IoT Platform console. You can delete a device regardless of the status of the device. After you delete a device from IoT Platform, the certificate of the device becomes invalid. Data that is related to the device is deleted, except for the IoT Platform logs. You can still query the IoT Platform logs of the device, but you can no longer perform operations on the device in the IoT Platform console.
Warning
- Before you delete a device in the IoT Platform console, make sure that the corresponding actual device is offline. If the actual device is online, the actual device continues to initiate connection requests to IoT Platform after the device is deleted from IoT Platform. If the number of requests exceeds the upper limit, IoT Platform starts request throttling. In this case, access of other devices within your Alibaba Cloud account is affected.
- After you delete a device, the certificate of the device becomes invalid and cannot be restored. Proceed with caution.
