My end goal is for the TV to work with Google Home.
Since its a Samsung smart TV from 2016 I first have to setup it up with SmartThings. Unfortunately, the new ST app doesn't have any option for the KS9000 model; but I'd read that the classic ST (older version) used to be able to integrate with it.
How do I get my TV setup for SmartThings?
I heard that Classic ST is completely shut down, so I haven't tried installing the older apk.

... how do you want it to work? ... have you considered an external device such as a Raspberry Pi or a micro PC?
