如何在删除实体本身时删除实体的遥测和属性

Question

I didn't find any information in the official documentation about whether the telemetry and properties are deleted after the device is deleted. However, when I check the database after deleting the device, the telemetry and attributes of the deleted device are still present and have not been deleted.

I want ThingsBoard to remove both the telemetry and the attribute values of this device when the device is deleted

ThingsBoard version: 3.2.2

You can either delete the device attributes/telemetries via Database query or Administration REST API. I would recommend the second option:

https://thingsboard.io/docs/reference/rest-api/

eg there is in an endpoint for deleting device attributes:
