Alby Hub is not yet on the Raspiblitz, just doing the basic research: https://github.com/raspiblitz/raspiblitz/issues/4727. Going through the docs it seems the best self-hosted option is to deploy on a VPS with a public IP address readily available: https://github.com/getAlby/hub/tree/master/scripts/linux-x86_64 The other option is using an instance of LNbits with the upcoming NWCprovider extension: https://github.com/riccardobl/nwcprovider Soon to be in a new LNbits release: https://github.com/lnbits/nostrrelay/issues/13. There can also use phoenixd and Blink @blinkbtc as well as the funding source.
