I have messed around with NUT to trigger a graceful shutdown of my home server running Ubuntu Server. I have struggled with setting NUT up on bare metal, but would like a gui anyway. I saw PVE-UPS which looks good, but I think but I think it is meant for Proxmox. Any alternatives, or a spin of PVE-UPS for docker compose anybody know about?

Note to self: Get around to wiring my UPS onto my management network for monitoring and graceful shutdown of non-essential stuff.
It’s also a good idea to gracefully shutdown anything essential that isn’t using a read-only rootfs. I’ve got my NAS configured to shut down after 5 minutes, but my firewall and frigate server keep running until the battery is almost dead, then safely shut down if the power still hasn’t come back yet.
What was the difficulty with NUT for you? The setup is pretty straightforward, IMHO.
Should be easy to wrap in a container, too.
I was hoping to setup a server and clients to shutdown the other Raspberry Pis and such, scattered around the house if the main server senses a power failure.
Also, I had an issue where it insisted on triggering a shutdown the SECOND the UPS triggered, even if it came right back. I might take another swing at it at some point, but I liked the look of that PVE-UPS things.
On clients you mostly have to set
MODE=netclientin thenut.confand modify theupsmon.confaccording to the manual and detailed manual. By default, it should only shutdown systems when reaching a “low battery” situation, not immediately when switching to battery power.
