Ah, so realistically it's only likely to be a good UX when combined with a paid download service. I think I know which one you're referring to (at least, I only know of one such service, which I learned about from Reddit).
I have an Amazon Fire Stick, which works flawlessly with Plex across my local network, so hopefully Stremio works as well on it too.
