Lots of questions though: are you looking for something non-custodial, must the payments be automatic, privacy requirements, etc.
Doesn't need to be automatic, but I'd like to generate an invoice from my Umbrel node. Ideally Lightning with in-chain fallback - there's a certain BIP-QR code for that.. I'm sure I'll figure it out, just tomorrow's my first day to invoice and gotta work out the kinks.
