Thank you very much.
I had noticed LNbits in umbrel, but didn't even imagine what it could be. I think this will help me a lot.
Also, by pure chance I stumbled upon a note from JonnyJi (npub1lm3…393g) where he shares a video from lunaticoin (npub1yn3…mzt0) that has helped me a lot to start off on the right foot with lightning nodes.
