What's the new Samsung smart TV device handler in templates?

I noticed if you go to add a device handler from a template there is a Samsung smart TV that has channel and volume features. Pretty much a whole remote. It didn’t work if I switch my TVs handler to it so that was a bummer. Is there a way to edit it so it would work with my TV? I wasn’t sure if anyone else saw it and tried already or if this is maybe old news. Just saw it and got excited hoping I would eventually be able to use it.
