UPS Handling with NUT

Proven on:

11 (bullseye)

As always...
Start with:	sudo apt update sudo apt upgrade

Network UPS Tools

Install NUT

• sudo apt install nut

Configure NUT

Select your mode

• sudo vi /etc/nut/nut.conf

MODE=netserver

(In my case, I've installed NUT on a VM and it'll be managing the UPS for the whole server...)

MODE options:

none	Disable automatic startup of NUT
standalone	This MODE is for local only configuration
netserver	This MODE is open to the network. (A NUT server)
netclient	This MODE is for client machines that will access a NUT server

Select your hardware

• sudo vi /etc/nut/ups.conf

[cyberpower]
       driver = usbhid-ups
       port = auto

(In my case, I'm setting up a CyberPower 1000AVR & connecting it by passing USB through to the VM...)

If your UPS isn't handled natively by the usbhid-ups driver, or you need to set options, start with the documentation for more details.
