I assume it is a ZWave device. In the ZWave database there is an entry for a device that matches your information: NIE Technology N4001 Mini Smart Plug
The database entry was added in January and is included in the OH 3.3 Milestone 1 release. Hence you have two ways forward:
- Update to OH3.3M1 or newer
- Use the binding snapshot for the ZWave binding from one of the milestone version of OH3.3 by placing it in the add-on-folder. Descriptions for how to do that can be found in the forum. But I will help if necessary

To double check that the database entry is valid for your device, please check for the XML file in the ZWave folder (should be something like “lib/openhab/zwave” and post it here. Or check it yourself in the database entry linked above.
