In my case, I've installed NUT on a VM and it'll be managing the UPS for the whole server...
MODE=netserver
 
== Select your hardware ==
* <code>sudo vi /etc/nut/ups.conf</code>
 
[cyberpower]
        driver = usbhid-ups
        port = auto
        desc = "A random surplus UPS"


(In my case, I'm setting up a [https://www.cyberpowersystems.com/product/ups/intelligent-lcd/cp1000avrlcd/ 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 [https://networkupstools.org/docs/man/ups.conf.html the ups.conf documentation] for more details.
 
== Start & test ==
* <code>sudo upsdrvctl start</code>
 
You should see:
 
Network UPS Tools - UPS driver controller 2.7.4
Network UPS Tools - Generic HID driver 0.41 (2.7.4)
USB communication driver 0.33
 
Possibly followed by a bit of information about your UPS
 
== Set up communications ==
(needed if you've set up as '''MODE = netserver'''...)
 
You can determine your servers IP address using:
* <code>ip a</code>
* <code>sudo vi /etc/nut/upsd.conf</code>
LISTEN '''192.168.2.219'''
LISTEN 127.0.0.1 3493
LISTEN ::1 3493
Where '''192.168.2.219''' should be replaced with the actual IP of the machine.
 
See [https://networkupstools.org/docs/man/upsd.conf.html the upsd.conf documentation] for more details.
 
== Set up access ==
* <code>sudo vi /etc/nut/upsd.users</code>
[upsmon]
    password = supersecretpassword
    upsmon master
 
See [https://networkupstools.org/docs/man/upsd.users.html the upsd.users documentation] for more details.
 
* <code>sudo vi /etc/nut/upsmon.conf</code>
MONITOR cyberpower@192.168.2.219 1 monuser supersecretpassword master
