Hey everyone, I recently bought a UPS and set up NUT. I followed TechnoTim’s guide but it seems to be a bit old. The config in his guide triggered a shutdown immediately when power was lost even if it was just a flicker. I saw in the comments of that page that someone had to add AT ONLINE * CANCEL-TIMER earlyshutdown to /etc/nut/upssched.conf file, which I added and that helped but now it just triggers the shutdown later instead of immediately. I find NUT config to be really confusing and I can’t figure out how all the different config files work together and what everything does exactly. Can anyone help me out here or point me to a different guide?

edit: I should also clarify that I don’t have exactly the setup that Tim has. I just have one proxmox server. I installed the NUT-server and NUT-client on proxmox directly and put the config files there. I also have a lxc with the client and webgui installed but I don’t think that part matters for this issue.
