@RyszI’ve searched around a bit but only found one similar posted question that was never answered. Does the plug-in allow for UPS event triggers to run an external script? I have it all running as a Netserver and slave for two Unraid servers, but I also need to run a script to gracefully shutdown a Ubiquiti UDM Pro router and my understanding is that I have to use a script to do that until Ubiquiti builds NUT into their software (if they ever do). Anyone else with a similar issue that can comment on how they solved this? Need both the method for executing a script and preferable another UDM Pro user that has a script that works. Thank you!

 

You can use the event hooks script with the NUT Configuration Editor in GUI:

Thanks @Rysz Is there documentation for this somewhere?

Not really, it's just a Bash script - so: https://www.gnu.org/software/bash/manual/bash.html

Essentially you'll put your custom commands inside the pre-defined event functions... 🙂 

 

Someone know why I cant connect to the NUT-Server via OPNsense?

in unraid nut settings rest your config set it to server and only change the password. and in opnsense set nut to client in both tabs and point it to unraid IP

Hi Guys

Is there any way that i can put the nut plugin working ?

 

If anyone is looking to get NUT running with MacOS, there is a great app called "UPS Power Monitor" (€8.99) which you install on one Mac in your network, then you install a separate helper "server" agent on each Mac (free / open source).

 

See here Power Guard

 

The app connects to your unRaid NUT server instance, then can shutdown your Macs depending on battery remaining, time on battery or battery percentage.

 

Very handy little app. I only looked into all of this because I had an iMac power supply blow due to a power failure recently, all wired machines are now on some form of UPS, with the main one that was already on the unRaid machine doing the heavy lifting.

After the last update (2025.02.26) ups.load is displayed as 0, although it is not. Before it worked correctly

It's not possible to display multiple UPS in the GUI at the moment.

It doesn't look like NUT supports your UPS from this mailing list conversation (although a bit dated):

No functional changes were made to the NUT package, please try to restart NUT (or another USB port).

Of course you are right. I made a ridiculous mistake, the plugin works perfectly. Thanks!

I would, however, need some advice. I need that when the plugin shutdowns the server, an mqtt command to be executed before. The solution I found so far was to copy the nut-notify script to /boot/config, modify it as I want, and every time the server is restarted, it is copied back to the /usr/sbin/ folder. Is there a more elegant solution to this problem?

Thanks!

Yes, you can use this script in the NUT Configuration Editor in GUI:

Put the commands you need inside the respective functions, in your case ONBATT_SHUTDOWN.

Make sure to edit the script from within the GUI so that the changes are also saved after a reboot.

I'm using the NUT Master Username and password and works fine for me.

 

When heading to Diagnostics, it took a few seconds to show up. Also check your Unraid syslog too, it tells you if theres a successful authentication

 

Followed: https://docs.opnsense.org/manual/how-tos/nut.html

Been using NUT with usbhid-ups driver for a while and everything seems to be working great expect not getting the UPS Load info. Ive tired enabling a Modbus on my APC SMC1500I-2UC and tried using the Modbus driver though it didn't work at all . appreciate the help.

Hi and thanks again for this plugin and the support you provide for it.
I have one more question. Is there anything I can do to get the Power Draw graph to be displayed? The power consumption is displayed correctly in the status bar and in the settings, but the history graph cannot be displayed no matter what I do. Is it possible?
Thanks!

Has anyone gotten the IS-UNITY-DP to work with NUT?

I cant seem to get NUT to connect to IS-UNITY-DP at all

 

EDIT: Looks like I got it working with snmp v2c!

I was having some issues with NUT that in the logs recommended enabling pollonly in upsconf but having done that now I'm seeing tons of "nut_libusb_get_report: Input/Output Error" messages in the log, and sometimes "nut_libusb_get_string: Pipe error", is this normal?

 

for reference, i have a CyberPower-1350VA UPS

 

tried taking off the pollonly  in upsconf, and now i'm seeing the same errors from before, which is the same error but with the additional suggestion to enable the pollonly flag

Mar 15 11:27:06 HTPC usbhid-ups[512654]: nut_libusb_get_report: Input/Output Error
Mar 15 11:27:08 HTPC usbhid-ups[512654]: #012Reconnecting. If you saw "nut_libusb_get_interrupt: Input/Output Error" or similar message in the log above, try setting "pollonly" flag in "ups.conf" options section for this driver!


any suggestions?

same issue here. cyberpower model: CP1500PFCLCDa

Apologies for the late response, driver spam is a common problem and can be mitigated with these settings:

• Enable Rule-Based Syslog Filters (in NUT Settings)
• Redirection for NUT Service Logs (in NUT Settings)

Generally if you don't have any problems with your UPS, these things can be filtered out / ignored safely. 🙂

It's possible your UPS does not report this value and it's calculated in the dashboards from other variables.

In this case it's not possible to show this in a graph as only actually reported variables can be shown in graphs.

 

You can hide the non-functioning graph though or change it to another (reported) variable of interest:

i did have an issue with 2 cores maxing out with no VMs running or dockers causing it (and causing transcoding to fail), and restarting NUT seemed to fix it, which is why i think i need to take this endless logging more seriously.

 

do you think this fix would address the issue i had?

Hello,

 

Can we possibly change 

Time on Battery before Shutdown (Minutes):

from Minutes to Seconds?

I am trying to get an ecoflow delta 3 plus to work with NUT. It is on the compatibility list, so it should work. However, I can't even get the NUT service to start. Right after installing the NUT plugin, without any changes to the settings, I get this error: 

 

"NUT was not able to start successfully - please check the SYSLOG for more information."

 

Syslog says this:

Writing NUT configuration...
rc.nut: Updating permissions for NUT...
rc.nut: Checking if the NUT Runtime Statistics Module should be enabled...
rc.nut: Disabling the NUT Runtime Statistics Module...
rc.nut: Network UPS Tools - Generic HID driver 0.53 (2.8.2)
rc.nut: USB communication driver (libusb 1.0) 0.47

rc.nut: No matching HID UPS found
rc.nut: Driver failed to start (exit status=1)

Any help is appreciated.
