Xiaomi smart plug issue

Hey,
I brought a Xiaomi smart plug from the internet.
This is the type that I can see in openhab: cuco.plug.v2eur

Its shows that this is not compatible, but I have found the json file in github, but I dont know where to put that or how to use it. Can someone help me with this?

See the binding readme.

in short: create the folder misc/miio in your config directory
drop the json file in the new folder.
restart openhab (so it picks up the new folder, alternatively restart just the binding)
