I asked the same question some time ago. I now use an old laptop with libreelec on it. https://beehaw.org/post/15312388

Yes I use Kore now and it’s great, but with a remote I can more easily give others control.

I think I will try Installing libreElec on my old laptop and see how that goes. I saw somewhere that the tv remote that the tv comes with might work because it sends the input through the HDMI. If that doesn’t work do you think IR remotes are better than Bluetooth?

I didn’t know a project like Obtainium existed! Thank you!
