February 24, 2025 - You can take those values, and use them in your UPS configuration (assuming you just have one UPS connected). Edit NUT's ups.conf file with sudo nano /etc/nut/ups.conf and add your UPS configuration. For example: [server-room-rack] driver = nutdrv_qx product = UPS desc = "Server Room Lowell Power Rack UPS" port = auto vendorid = 0665 productid = 5161 bus = 001

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?
