Jellyfin is very conveniently packaged in docker, so while it may seem daunting, I highly recommend at least trying that route.

Running an nfs mount, docker or not, should be perfectly fine. Jellyfin just uses normal storage so won’t care if it’s nfs. No real special considerations with proxmox either, especially without worrying about a dedicated GPU. Just spin up a Debian guest and go.

If you have a free pcie 4x or higher slot, you can throw in a cheap card to adapt to m.2 nvme, like 12 bucks. I’m running one in my older hp desktop that doesn’t have m.2 and it’s been working great.

We need more info on your permissions. 755 would mean anyone can read files there, but only the owner can write. If the owner isn’t the same user that mediawiki is running as, then uploads won’t work.

I have no way to test this with the equipment I have, but what about opnsense on an x86-64 box and throw an sfp+ pcie card in there. You could then in theory turn off auto negotiation and set it to 2.5g. Has anyone out there tried this?

I’ve been running opnsense with my CenturyLink 1g setup, though I’m still using their ont to convert to copper, and been very happy with it.

I’m pretty sure sensi thermostats, when controlled by home assistant, do what you want. I haven’t confirmed they don’t still try to phone home, but that could be dealt with by some firewall rules. Other thermostats that support homekit should also work.

I do almost exactly the same, except I have opnsense running on a cheap dual nic mini PC so I don’t have that dependency on my proxmox servers. The unifi stuff does need a controller, but they publish a free app that you can run instead of getting their hardware.
