That's the solution I used in the end too. It was for my parents TV, which is a smart TV with an OS that just sucks. I have a server with Jellyfin and every time they wanted to open that, they had to navigate to the app store, open that, open "Web App Tester" and then click the link for Jellyfin. The TV was also really slow in general, it always took like half a minute to connect to our WiFi after turning on and it randomly started to flicker. Then I found the Xiaomi TV Box, which comes with a bluetooth remote and can be hooked up to a TV over HDMI. It runs Google TV, which is just the new name for Android TV, so it has Jellyfin as an app and all the other issues were fixed as well. I know that still sucks privacy wise but my parents don't care about that and they just wanted something that works. We also wanted to replace the smart TV with a dumb TV at first but all the dumb TVs we could find were a lot smaller and only 1080p instead of 4k, so we just disconnected the smart TV from our WiFi. This new setup is an improvement in every way and we can replace the TV itself and the Xiaomi TV Box independently if we ever need to.
