So I looked at BTCPayServer.
Is there a guide to setting that up together with a Lightning node on my own homeserver? I am not ready to orange pill myself.
Yet.
But the world is giving me more reasons to at least consider it.

Why do you need it for?
How technical do you want to get? Do you plan to run it on dedicated hardware?
BTCPayServer setup is really easy. You basically run a shell script that does everything. I wouldn't run it on your primary computer, though. I found it to be pretty heavy handed.
Umbrel is the easiest way to go. I run it on a pi4. There are lots of other self hosted solutions, though.
I think there are others as well.
