I believe in the base game you can see them from a button to the right when you’ve opened a chest.

Sounds like a pain to configure compared to some of the more designated systems. Is the advantage that you use Ubuntu for other things as well, so it’s a more multifunctional system?

I don’t mind which software, I could absolutely use openwrt instead. Assuming I do, which hardware might I need?

That’s a good point, I’ll see if I can figure out the power draw of this system somehow. Any tips?
