When I first setup my 2 Umbrel nodes, originally RPIs with 4GB + 2 TB SSD & 8GB + 1TB SSD respectively, I used the Lightning node itself to open channels using https://amboss.space/ and https://lightningnetwork.plus/ to find suitable nodes.
This was easy and cheap at the time. I remember setting up several triangle nodes to small capacity nodes on my first Umbrel and several large capacity channels to large public nodes on my second Umbrel. I also setup large channels between my own two nodes so I could route payments across my own network. I was experimenting heavily.
To rebalance, I installed RTL, Ride the Lightning and Thunderhub, but quickly realised that RTL was the tool for me. I also installed an auto rebalancing tool called LNDg, which I spent many months watching YouTube videos and reading articles in a failed attempt to master.
Umbrel doesn't mount external hard drives for some reason.
My Umbrel home mounted my RPI SSD drive to migrate across successfully.
But I haven't tried adding additional storage to date.
It'll only install to one hard drive and then it will not recognize any others.
You can program your routing and balancing yourself with lnd-rest - it's easy python 😁
Good old triangle swaps. Good times.
Things were better before the war 😂
Lndg is great. Set it to rebalance at 70% of Channel fee and let it fly.
It has a nasty anti pattern though:
Your channel liquidity gets drained instantly at a low fee. So you rush in and raise the fee.. And lndg quickly rebalances at that higher fee 😂
