Thanks! Great post! I have been strugling with my lnbits instance at my home umbrel because of the difficulty of making the extensions to work on clearnet (using a domain+ proxy vps + tailscale but some extensions do not work). Also umbrel is not updating the app. Question can a 1 core 1 gb ram vps run lnbits instance?

I am planning to connect the home node with the lnbits instance using tailscale, which I believe is possible.

Yes. A simple linux pc could handle it. Lnbits do not use such resources is just writing to a simple database like an excel.
