Is this doable with one UPS? I’m thinking of the signal wire so the device knows it’s running on battery and has to shut itself down sooner or later. We have 2 (who need shutdown, +1 can just lose power I guess) different devices mentioned here.
I have one older APC UPS on the PC and one newer Eaton UPS on the NAS. Each UPS has a signal port with a cable connected to the main device that runs some software to notice when it’s on battery and supposed to shut itself down after X minutes battery time.
The NAS UPS also has the router, phone and zigbee hub connected, but only the NAS will shut itself down, the rest will just lose power at some point, but those don’t matter.
How do you get the server and NAS to both get the signal and both shut down after X minutes? Is there a specific UPS features required?
