NUT on my Pi, so my servers don't die - Jeff Geerling
February 24, 2025 - Configure the UPS monitor on the NUT Pi by editing upsmon.conf, using sudo nano /etc/nut/upsmon.conf: # Make sure you use your actual admin password... MONITOR server-room-rack@localhost 1 admin ADMIN_PASSWORD_HERE primary # You might also want to configure FINALDELAY and set it to a period long enough # for your servers to all shut down, prior to the primary node shutting down and # triggering the UPS to switch off its load, e.g.

August 20, 2024How to configure a NUT server for a UPS connected via Ethernet to my switch via fixed IP address?
Network UPS Tools is for MAKING UPS-availability network aware. You'd need to find if nut-server supports getting status information from (and even better, controlling) your Eaton over the network. Then setup nut-client (upsmon) to the nut-server. Typically nut-server controls direct wired UPSes, serial or USB. More on reddit.com

r/homelab on Reddit: A UPS that shuts everything down across the network? How do I accomplish this?
July 18, 2024 -
tl;dr: I'm looking for a local (non-cloud), free solution that would allow a 1U UPS to trigger a shutdown of a nearby PC running proxmox, plus two nearby synology NASes, and a Windows PC in another room.
It's time for me to buy a good 1U UPS for my homelab. My lab uses around 300 Watts of power at its peak, according to a small CyberPower UPS I currently have everything connected to, although I expect power demands to grow over the years. The lab currently consists of:
-
1 PC running Proxmox, with maybe a half dozen LXC containers and VMs
-
Two old 8-bay Synology NASes
-
UDM Pro router
-
12-port Ubiquiti switch
-
A little Ubiquiti Fiber GPON box
What I really want to accomplish is to make the UPS trigger a safe shutdown on the NASes, the Proxmox box, and one or two PCs deployed in other rooms. I want to do this without having to pay any kind of subscription, and without relying on any remote cloud software.
Has anyone ever deployed anything like this? Which UPS manufacturer did you use? What sort of deployment would you recommend?

Network UPS Tools Overview
This information is cached by the network server upsd, which then answers queries from the clients. upsd contains a number of access control features to limit the abilities of the clients. Only authorized hosts may monitor or control your hardware if you wish. Since the notion of monitoring over the network is built into the software, you can hang many systems off one large UPS, and they will all shut down together. You can also use NUT to power on, off or cycle your data center nodes, individually or globally through PDU outlets.

r/homelab on Reddit: How to configure a NUT server for a UPS connected via Ethernet to my switch via fixed IP address?
October 29, 2023 -
Hi, all the quickstart guides just mention the USB connected UPS configuration method, asking first to run this command 'lsusb' to get UPS device IDs etc.
However, my UPS Eaton 5P1550IR is connected to a ethernet switch and has this IP 10.0.0.7 . How do I configure the nut server on a Debian machine (Proxmox VE) with IP 10.0.0.1 ? The only 2 commands I ran so far are:
sudo apt update sudo apt -y install nut
When I go to 10.0.0.7 I can see and login to the Eaton UPS web interface:

All the guides I found online just mention USB method:

Multiple UPS on the same NUT-Server • Aaron Weiss
December 30, 2021 - Unfortunately, NUT has yet to update their terminology to more modern naming of primary and secondary devices. After adding that, you’ll want to restart the monitor server with sudo systemctl restart nut-monitor as well as the driver. This will again restart the connections to both UPS devices and should show they are now established.
