I did the same for a while but then I was on Holliday in Italy and it was painful trying to get the internet fast enough to stream my media over tailscale.
So now instead, I just keep everything on a laptop running Kodi and if I’m going somewhere, the laptop goes too. No worrying about internet connectivity or bandwidth. Just content ready to go.
I get that this doesn’t work for everyone’s use case. But I thought I’d share anyway.
