Thanks, here's my problem. I finally got Core Lightning running and connected so that I can collect sats from my Bitaxe mining on Ocean. (lightning payouts require Core Lightning). I cannot add Alby Hub in Umbrel without an LND lightning node. I've seen dire warnings about trying to run two different lightning nodes on an Umbrel. I'd like to try Alby with a Cashu backend but I don't know how. Is it feasible to run Alby Hub on a laptop that is not kept running all the time? My home laptop is a Linux Mint device.
