Homatics Box R 4K Plus

First off, big thank you to all the devs, for this incredible progress with Dolby Vision and everything else you do. I have a few questions about this device.

  • Does the included remote work in IR mode or Bluetooth? Does it need a separate IR receiver?
  • Is it S905X4-J or S905X4-K? What is the difference between J and K suffix?
  • What is Dune? App or another device brand? Is it needed for CoreELEC or Dolby Vision?
  • Says here that we need a display with Low Latency Dolby Vision? What is that? Does my Sony X900F support it?
  • Some posts here and on the website of this box mention it does not do passthrough for some audio codecs? Is that true? If so, why? Isn’t passthrough about what the receiver supports and not the device? My X96 Max Plus can passthrough everything. Does it support passthrough for TrueHD, Atmos, DTS:X, DTS-HD MA, DTS, Dolby Digital, Dolby Digital Plus?
  • What is the USB-C port on the back for? Can it be used instead of the DC power port?
