If a device is decommissioned or has a security risk, you can delete it from IoT Platform, regardless of its current status. After a device is deleted from IoT Platform, its device certificate is invalidated. All other data associated with the device is also deleted, except for previously generated IoT Platform logs. You can still query the IoT Platform logs, but you cannot perform any other operations on the device.
The physical device must be offline before you delete it from the IoT Platform console. Otherwise, the physical device continuously sends connection requests to IoT Platform after it is deleted. If the number of requests exceeds the limit, IoT Platform triggers its throttling mechanism. This can affect the connectivity of other devices under your account.
After a device is deleted, its device certificate is invalidated and cannot be recovered. Proceed with caution.
Procedure
Log on to the IoT Platform console.
ImportantIf you use an Alibaba Cloud account to delete a device, IoT Platform sends a text message for validation.
If a Resource Access Management (RAM) user deletes a device, IoT Platform does not require text message validation by default. To ensure device security, create custom policies for fine-grained permission management. For more information, see IoT Platform RAM authorization and Custom policies.
