This is very cool!
Have you considered something like Tailscale so you can securely access it from outside your home? I've been thinking about spinning up my own home server that way, seeing as Tailscale makes it easy to securely access it from my phone when I'm out and about.
I just stumbled on a self hosted project similar to tailscale: https://github.com/gravitl/netmaker. There is also https://github.com/juanfont/headscale which is an open sourced implementation of the Tailscale coordination server. Tailscale "just works" and makes things incredibly easy for personal use, but it's awesome that there are also similar self-hosted options out there
