Does your Linux server actually know when the power is failing?

NUT (Network UPS Tools) is the go-to open-source solution for UPS monitoring on Linux — but it takes some know-how to set up properly, especially with hardware that isn't auto-detected out of the box.

This detailed guide covers everything from finding the right driver, dealing with stubborn read-only settings, configuring automatic shutdowns, and setting up email alerts so you know when things go wrong. There's even a section on how to safely test your shutdown logic before a real power cut hits.

Great resource for anyone running a homelab or Linux-based home server. 👇
