I bought a Start9 server, installed bitcoin core, installed lnd, then I installed Lightning Terminal and connected it to Zeus via LNC, added some bitcoin, then opened a Tor channel to SN. Later I installed Alby Hub to connect it to SN.

Once I had issues with my Tor channels, and wasn't home, so had to ssh in to restart Tor. Other than that, the only real maintenance is updating software with a click and monitoring my channels in Zeus to make sure they aren't imbalanced. At some point I'll probably automate swaps for keeping the channel balanced and I can avoid the channel checking part.

In the average month, I'd say it's about 5 minutes of work and whatever the electricity is in terms of money.
