I used mostly this, but had to customize it a bit I think to get things working right. NUT feels like a super finicky system, but in the end it does work. My biggest issue right now is that it only reports a new status update to Home Assistant every few minutes, so the actions don’t really get a chance to trigger before the server shuts down. It also shuts down with the UPS at way too high of a percentage remaining, so I need to figure out how to make it wait just a little bit longer before the power down. It wants to power off like < 2 minutes after the power goes out…
