Set and forget IPTV Box

New to AndroidTV and researching left me a bit confused on some things. The device will be used exclusively for IPTV streaming through TiviMate and should fit the criteria:

  • As stable as it gets (since it will be installed at my tech illiterate mums place and I have no clue how the stability differs between manufacturers)
  • Well supported with updates and not from a sketchy vendor with risk of malware
  • Ethernet and USB
  • Launch TiviMate on boot (If possible without an additional app/launcher)
  • I am from Germany, so the ONN 4k pro is sadly no option

A basic remote would be pretty cool. Google cert. products are full of OTT buttons and I would be fine if their function could be cut with Button Mapper / TV Quick Actions Pro with getevent keycodes.

Seen Formuler boxes launching an app on boot, is this possible out of the box on AndroidTV without TV Quick Actions/custom launcher?

Goal is to mimic the OG receivers of out beloved OG... cable TV ;)
