A pi (shhh! Don’t tell Darth).
It’s worked well but the last few months my umbrel has been very Unstable. I can’t ssh in or access via the web browser. Only way I can get it back is by shutting off the power. I think this time I am going to hook up a monitor to the pi to see what’s going on. See if I can power down safety from command line. If not then this will be the last time I power cycle it. Close the channels and move the funds to a fresh LND node on more stable hardware. Just sucks to do this node is like 2 or 3 years old
