Is mostly a interface for linux distros, so AndroidTV won’t work.

Jellyfin Media Player (desktop app) have a TV UI, which kinda woks, on the article mentions an YouTube app called VacuumTube.

Is more an alternative for DIY home theater PC (like Kodi) than AndroidTV

Also RedReader

My long-term vision for RedReader is to restructure the app to more easily support other sites, including Lemmy, and perhaps others such as Tild.es and Hacker News. Before the API changes were announced, I was already considering adding RSS reader functionality to the app, and I think it would be cool to work with some kind of “open forum protocol” which would allow a variety of websites and apps to interoperate with each other through a uniform API.
