In order to make the creation and management of devices within Thingsboard consistent, they created the platform assuming that all data that is used in their platform is formatted the same way. To make this possible they created something they call "Data convertes" that processes incoming data and formats the data accordingly. The converter expects a timestamp as well as a device name, any other expected fields must be defined within the data converter. The data converter is used within an integration, the device name links the upload through the integration to a device.
