Just noticed that lineage is has an android TV build for the odroid c4, which is USD $54 (way cheaper than a pi) and you can get an ir remote for $5 and a case for $5.
Couple that with f-droid and the jellyfin android TV client, and that seems like it should be good, no?
Identical setup here, N2+ running CoreELEC with the Jellyfin add-on.
No complaints here.
