if you want LND in your pi:
1) is LND installed and running and synced?
normally you do that on the command line with lncli I guess. - how did you install LND?
2) if synced. then we go to alby hub.
how did you install Alby Hub on that raspberry pi?
(and again, I doubt you will be happy with a pi+lnd+albyhub at home setup.
maybe ask here if somebody has a “sub wallet” on their node for you.)
