Yeah, smart TV, never connect it to the 'net, get a used shield pro, ADB and side load F Launcher. No ads.
Shelds remote can control the TV volume and its connected via HDMI and the Shiekd Pro remote switches both off and on. I use Kodi, Prime, Smart Tube Next and a couple local TV apps.
Not what u want but that’s where I am and it works well.
Be interested to see the responses
Is there a how to for Linux?
