r/homelab on Reddit: Super simple NUT UPS for Windows?
December 6, 2023 -

I'm trying to figure out if there are any *simple* ups management tools for Windows, that can speak to a NUT daemon? From what I can see, there *is* a NUT daemon for Windows, but it is kinda complicated to install and configure.

What I am ideally looking for is something as simple as a WMI32_Battery instance, that can be configured with the address and creds of a NUT daemon, and makes that data available as a Battery. From there, built in Windows functionality can be used to determine what to do when power fails, battery gets low, etc.

NUT UPS on Windows 10
I'm currently using Windows NUT Client on a Windows 10 machine. A Synology NAS is acting as the NUT server. The UPS is a Cyberpower 1500PCFLCD. It more or less works and shuts down the PC properly. https://sourceforge.net/projects/winnutclient/ Maybe this will work for you? More on reddit.com

Super simple NUT UPS for Windows?
which client? the win nut client is pretty straight forward to install (a .msi file) and then you just configure the username/password/address of your nut server and it connects. Once you've got that done just configure your shutdown parameters and bob's your uncle. More on reddit.com

August 20, 2024 - The system is Windows 11 Pro with 23H2 and Intel(R) Core(TM) i7-10700KF CPU with 16.0 GB Memory (Mainboard is Gigabyte H410M H V2). The UPS is a Riello Sentinel Dual 4kVA SDU 4000 and is connected via USB (this all works fine in the PowerShield software they suggest using). I've looked into this and tried to 'install' libUSB but this seems to be a a folder with "files" in it but no exe file to 'install' from looking at the NUT site it suggests that SDU 4000 is compatible using the [riello_usb] driver https://networkupstools.org/docs/man/riello_usb.html)

r/homelab on Reddit: NUT UPS on Windows 10
March 27, 2020 -

A while back in asked about how to connect multiple computers to one UPS device (post). I received excellent advice to use a Raspberry Pi to run a NUT server to do this. I'm now the proud owner of a RPi4b 2GB ram and have installed NUT and it's working well locally thanks to this tutorial.

I'm not trying to connect it to my Windows 10 machine and I'm just having a frustrating time doing so. I've first attempted to install WinNut, even though it seems like an ancient relic. Although I'm certain my credentials are correct, I receive this error when I attempt to start it:

Level INFO 03/27/2020 17:59:28 In winNUTServiceMain- Received service command ID: 1

Level ERROR 03/27/2020 17:59:29 Can't login to UPS [ups@192.168.1.3]: Access denied

So instead, I installed the Binary packages for Windows and I see it's been installed but it's not running, even when I try to under some command in command prompt. I've entered my MONITOR entry and the netclient in the confg files.

At this point I'm just over my head and could use some help. I've Googled as much as I can and I just don't see any helpful guides on using NUT on Windows.

If I can get this working, I think it would be helpful to others too.

P.S. I bought a separate NETGEAR POE Switch to power the RPi with a POE hat so I had less cables going to it. The primary goal is to go from two UPS units to one for a more minimal setup. RPi has been super fun and I think these are just the darndest little machines.

Since NUT v2.8.5, using nut.exe -N for testing and pressing Ctrl+C should cause the started daemons to be killed off. Previously they would linger and e.g. preclude subsequent experiments with the service wrapper. Console close events are ignored, so there is a way to indefinitely keep the daemons started by the test-mode wrapper running (kill later if needed via Task Manager). ... Install as a Windows service called "Network UPS Tools" (if not yet done), and try to start this service.

Network UPS Tools - Features
There is also a port of the client-side monitoring to Windows called WinNUT. Your system will probably run it too. You just need a good C compiler and possibly some more packages to gain access to the serial ports. Other features, such as USB / SNMP / whatever, will also need extra software installed. Three layers: drivers, server, clients. Drivers run on the same host as the server, and clients communicate with the server over the network. This means clients can monitor any UPS anywhere as long as there is a network path between them.
