Hi All,

Apologies if this is in the wrong community.

I’m looking to get a UPS for my home server. It runs Homeassistant, Plex, and a few other things. I mainly need something to protect from power flickers/blips, and for it to allow a proper shutdown for prolonged power outages.

Here is the power useage on all my devices:

  • Server: 350w
  • NAS: 90w
  • Router: 42w

Any info on what to look for or which model to buy would be greatly appreciated.

    Look into NUT, Network UPS Tools. It runs in a server/client type of set up. You’d install the server onto the device that has the UPS data connected to it. It then monitors the UPS status and can tell all the clients to shutdown when the UPS is running low.

      Hm but that adds a lot more complexity, as then every single network item has to have an UPS as well, right? Certainly not a problem for a company with server room and racks. But at home in a house, the hardware might be spread out across rooms and floors. If there is a switch somewhere without UPS, it will cut off certain clients from receiving the signal via network upon power outage.

        I don’t think an additional UPS is really necessary here. I do have switches to other parts of my network, but they’re just for TVs and game consoles, so I don’t really think a UPS is needed there.

        It’s mostly a failsafe so I can poweroff my NAS properly rather than corrupting data. Since my server and router are on the same power strip, it makes sense that they’re all on the UPS since they’re the 3 main items interacting with each other.

        Something with NUT as boothin@kbin.social mentioned might be a good option so it can send alerts when it’s activated. I’ll have to research that more.

        Edit: figured out how to mention other users.

        Typically you’d have a server running on a device on each UPS, and the clients would be the other devices also plugged into that UPS, so when that UPS is low, everything plugged into it will turn off. If you have another UPS elsewhere in the house, you would have another server installed on a device there so it can monitor that UPS that it is plugged into, and tell the other devices also plugged into that other UPS to shut down. Without knowing the layout you are running though, there’s no way to know if NUT is what you need or want.

        So in your case it would likely be to plug your server and nas both into the same UPS, and when the server detects the UPS is low battery, it will tell the NAS to shut down. This would also require the switches/router/whatever to also be on a UPS to hold power of course. So then it basically becomes each little cluster of devices that need UPS would also have a switch nearby that is also on the UPS

        True, but wouldn’t those scattered devices already be down because of the power outage? If they are in a different room they would probably need to be on a different UPS anyway.
