Monitoring a UPS with NUT on the Raspberry Pi
February 28, 2026 - In the step “Installing the Nut-GUI Server” the file that needs editing is hosts.conf and not host.conf. The current command is missing an “s”. Instead you should run the following: sudo nano /etc/nut/hosts.conf ... Thank you for the heads up, it is much appreciated. I have now corrected the typo within the tutorial.
How to NUT
So you start by rubbing slowly… wait a second this is r/homelab 😂 So you can install NUT directly on Proxmox since it will be easier to control the host itself. From a container you will need to do a bunch of hacks so it will be able to shutdown the host and at that point it will just make using a container kind of pointless. Here is a simple tutorial to get you started - https://wiki.debian.org/nut Yes generally it’s recommended to not install software on the host directly, however for hardware related things and general system utilities like NUT and Sysstat this doesn’t really apply.

August 27, 2023Does anybody have a good guide for configuring NUT UPS in a client-server config?
I know this isn't helpful to you but I've always wished Proxmox would do more to bring UPS support to the GUI.
But that said one important step is make sure all your guests automatically shutdown when you shutdown your host.
I haven't used it, but this thread may be a good starting point. https://www.reddit.com/r/Proxmox/comments/gsts3a/are_there_any_guides_for_setting_up_nut_for/

February 24, 2025 - You don't have to use a USB connection, though it's the most common across all the modern UPSes I've used. To make the Pi run as a NUT Server, and not just for local monitoring, edit the upsd.conf file with sudo nano /etc/nut/upsd.conf and add a LISTEN directive:

Network UPS Tools - ArchWiki
A monitoring daemon (upsmon) which monitors the upsd server and takes action based on information it receives. The idea is that if you have multiple systems connected to the UPS, one can communicate the status of the UPS over the network and the others can monitor that status by running their own upsmon services. NUT has extensive documentation on the configuration however this is going to walk through a simple setup of a USB UPS and the associated server and monitor all in one system (common desktop configuration).

r/homelab on Reddit: How to NUT
August 27, 2023 -
Hi all, just picked up a UPS and looking g for advice on how beat to set up NUT.
Should I configure directly on my main proxmox server, as a lxc running on proxmox,do something on the NAS or on a Pi4 which I have floating around?
Proxmox server is mains powered and would be connected directly to the UPS, while the Pi is connected to my switch and powered via POE. I know all options are possible but looking to get feedback on best practise
EDIT: All setup and running with connections into my 2 synology NAS, and monitoring using the NUT integration in Home Assistant. Next trick is to work out how to use the UPS trigger points to shutdown my other Proxmox host (runs PBS, Plex & PiHole) and Home Assistant

June 18, 2021 -
CyberPower 1500VA UPS; 2 x PVE 6.4-8 in a LAN CLUSTER
I would like one node to act as the NUT server which will be connected to my UPS via USB and then my other Proxmox node to act as the client.
In case of power outage, I want NUT to initiate a shutdown of both nodes after ~10min.
Does anybody have a good guide or can provide some sample config files for this setup?
Thanks for the help!

My setup is a pfSense router that has the UPS(CyberPower) usb cable attached to it, and proxmox looks to pfSense for it's UPS data. This is the minimal settings needed to get this kind of thing working.

In this example 192.168.10.1 is the IP-Address of the green interface. You can skip the port number 3493 as it is the default port. To configure NUT in a standalone configuration only these lines are required as IPFire only uses IPv4.
