https://blog.tyk.nu/blog/going-nuts-using-a-ups-on-freebsd/ provides a good overview of NUT components (as of v2.7.4 release), and some smart tricks for shutdown and alerting setup on FreeBSD.

Welcome to the Network UPS Tools (NUT) project Wiki, and feel free to contribute tricks and insights.

While there are several good entries in the menu, ones referenced most frequently in issue discussions include:

Building NUT for in-place upgrades or non-disruptive tests and Using NIT (NUT Integration Test suite) sandbox
Technicalities: Customizing (NUT) config files and scripts delivered by packaging
Links to distribution packaging recipes and repository sections
Troubleshooting upsdrvctl drivers not starting ("insufficient permissions on everything" or "Can't claim USB device [VVVV:PPPP]@0/0: Entity not found") possibly due to nut-driver-enumerator (NDE) services having been there before you with NUT 2.8.x, and "insufficient permissions" when starting USB drivers for a different PoV on this; see also an example unit deployment detailed in NUT systemd service units page
Changing NUT daemon debug verbosity
Building NUT integration for Home Assistant
Running NUT in an LXC container
Troubleshooting eventual disconnections (Data stale) and CyberPower Systems (CPS) know-how
NUT for Windows
NUT HCL and DDL
Code contributions, PRs, PGP and DCO
NUT CI farm

Also keep in mind the documentation links from NUT website and the FAQ in particular.
