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?
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.
