NUT Package (2.8.1 and above)

I see and it makes sense. Thank you both!
Looking to purchase a few more UPSes - any particular model that is 100% compatible with NUT and you can truly recommend?
min 700VA, cheap (<$200) and rack mountable would be ideal

NUT is compatible with a wide variety of UPSs. That said, some UPSs have more quirks than others.

Specific recommendations are difficult, but I would generally stay with usb-hid capable units from one of the big manufacturers such as APC, Cyber Power or Tripp Lite.

My personal preference is for APC, but they tend to be a bit more expensive.

Hi @dennypage

thanks so much for your tremendous effort on this package. For months now after upgrading pfSense my previously working (most likely pre nut 2.8.x) Eaton 9SX 3000i keeps loosing the USB connection. A restart of nut fixes it immediately. I tried to work my way through the thread but seem to be at a loss. Everything is running as root already. I have not applied quirks. I am on nut 2.8.2. I have not set things to interrupt. Using usbhid-ups with no additional parameters.

Any (!) hint on how to further debug this, where to look in the logs, make adjustments whatever would be greatly appreciated!

Check also NUT suddenly stops working every app. 6 minutes.
It's also a "The UPS is a usb connected Eaton 9SX 3000i.".

@Gertjan turns out it is my thread and still an unresolved problem. I just had forgotten I was already working on it here in the forum. :-)

No quirks installed. Problem persisting.

Do you see the disconnect in the system log ?

Normally, like a mouse, or a printer, ones the USB link is made, it stays up until 'something' happens'.
Btw : I said 'link', be ware a simple USB connection it a lot more more then an simple electrical link. USB connectors, the wire (the cable) etc can be in a bad shape. USB concentrator (the USB chip) used on both side can be 'military grade' or worse then 'alibaba' grade.
"APC", as mentioned above, delivers the close to set it and forget it (and their battery still dies at a worst moment ... )

To test your UPS : forget about the genric NUT = pfSense for now. Hook it up using a desktop top PC, with the software that came long with it.
Check for some time if you see 'disconnect issues'.

Have look at this page : https://networkupstools.org/docs/man/ and locate (couldn't find it myself right now) the schema that lays out how all this stuff is interconnected.
You'll find details about upsd - the ups deamon, the connection method, which is 'USB' in this case, the driver (usbhid) used, "upsmon".
There are command line tools that can give you a lot of details :

[25.03-BETA][root@pfSense.bhf.tld]/root: upsc UPS
battery.charge: 100
battery.charge.low: 10
battery.charge.warning: 50
battery.date: 2001/09/25
battery.mfr.date: 2024/06/19
battery.runtime: 500
battery.runtime.low: 120
battery.type: PbAc
battery.voltage: 13.3
battery.voltage.nominal: 12.0
device.mfr: American Power Conversion
...

but a USB that 'disconnects' is, imho, more a hardware issue, like a cable or connector, or a bad power issue.
UPSs have often internally bad power ( ) as they do ugly things with power - it's their job.

@Gertjan is it fair to assume that I would be seeing and usb disconnects the kernel is aware of in dmesg?

I just intentionally pulled the USB:

ugen0.2: <EATON Eaton 9SX> at usbus0 (disconnected)
ugen0.2: <EATON Eaton 9SX> at usbus0

However when nut stops working there is NOTHING in dmsg indicating an issue. Moreover: Once it stops working a simple restart of the nut service makes it work again immediately. If the USB stops working due to a hardware issue I would suspect that the problem would persist. Vice versa: When I pulled the USB and reinserted it, NUT was immediately happy again and did NOT loose its connection. Indeed it did not even throw an error in syslog...

So if this was a problem on the Eaton or a physical problem I would assume that I should be seeing usb related dmesg/syslog output. I do not.

Moreover the problem started pretty much when I upgraded from 23.x to 24.x. What was the nut version with 23.x? I read somewhere that nut 2.8 has introduced some usb related regressions. Agreed it could be unrelated but the timing is very suspicious.

I upgraded from 23.x to 24.x.

For what it's worth : I switched to 25.03 Beta 6, the one that came out last week, and its rock solid.
I only use the beta on my work, at home I still use 24.x as I can only upgrade @home to the offciial version as per my boss's rules (the home wife).
At work, Im' the boss (a hotel with many connected clients) so I can use the beta over there.
It's, imho, perfect.

One thread please...

There is now a UPS Tools section, so I ask everyone to use problem specific threads rather than continuing this thread. Thank you.
