@mattrivett what is interesting is that the debug log you posted on nut-upsuser showed a different path through the scaling code, though I guess that was from code newer than v2.7.4. From above:

   0.211353     Path: UPS.PowerSummary.ConfigVoltage, Type: Feature, ReportID: 0x05, Offset: 16, Size: 16, Value: 0
   0.211484     ConfigVoltage = 0 -> assuming correction factor = 1e+08

From the list:

   0.208056     [D3] Report[buf]: (5 bytes) => 05 36 00 30 00
   0.208187     [D2] Path: UPS.PowerSummary.Voltage, Type: Feature, ReportID: 0x05, Offset: 0, Size: 16, Value: 0
   0.208311     LineVoltage exponent looks wrong, but not correcting.

   0.208718     ConfigVoltage exponent looks wrong, but not correcting.

Clearly needs some more debug info, especially since this version seems to still be truncating the scaled "Value" printouts.

@xztraz I posted an explanation on the list about where to look for some of the other values. It might be hard to implement with the current code structure, though, because NUT uses the "Path:" IDs for looking things up, and the "Undefined" items are indistinguishable from one another (except via the ReportID, which is really more of an internal ID, and is not exposed to the HID-to-NUT matching tables like in drivers/belkin-hid.c).

In my earlier posts I installed NUT using apt-get nut on an RPI3. The RPI I also run as to get VPN access into my home network. I wanted to upgrade to get faster ethernet and processing however it really isn't required. The latest output is from compiling nut master on the RPI4.

Thanks for all the information. My goal is to get this data out of the UPS into MQTT that I then historize into a PI server. I am doing that using a modified version of this script for a CyberPower UPS and it works well. https://github.com/dniklewicz/ups-mqtt

I guess I can just leave the driver running and pipe it into a file for now. I've recorded video of this type of thing to provide data to decode sensors for rtl_433. Then you can see in real-time the output and the LCD and the data being received. That might help. I also have the software that came with the UPS that I haven't even installed yet. I could see if that provides any useful information.

Note that since 2020 several PRs were merged to update liebert-hid.c, so recent builds from NUT master branch (and eventual 2.8.0) might support this better. Any tests and reports back if it actually does would be welcome.

I have a similar issue where input and output voltage seem to be missing. If the UPS is plugged into my Synology, it will provide me the values - but when I plug it into a system with full NUT, I don't get them. I should see what they are doing..

@sebastian-tennant : what does Synology say (assuming it has another NUT version) about the driver.version.data (and the version itself)? Is it by chance MGE, maybe 2.7.4 based?

There is a overlap and difference of the two mapping tables, with some devices with same VID:PID marketed as one or other brand with different capabilities.

NUT 2.8.1 release (and later master branch code) added a subdriver option for usbhid-ups so users can pick their preference (and use USB IDs not built into binary drivers). Of course, bets are off here about actually supporting the device or confusing it into bricking... (well, gotta have a disclaimer here).

@jimklimov They might be doing some proprietary magic. This is the output from the same UPS, just plugged into the Synology:

Thanks! So, diff'ing the two data samples - I see they have a different synchronous setting (impacts how drivers send into the pipe to upsd) but with so few data points it should not matter regarding buffer overflows. Still, worth trying to flip yours on the "system with full NUT".

Another is the apparent difference of NUT releases involved, with Synology version looking like NUT v2.7.4; at least its sources have the identifying strings:

drivers/belkin-hid.c:#define BELKIN_HID_VERSION      "Belkin/Liebert HID 0.17"
drivers/usbhid-ups.c:#define DRIVER_VERSION             "0.41"

I'm not sure which exact commit your "2.8.0.1" build is made from, but versions 0.52 and 0.18 are around for some time, and are newer than 2.8.0 release.

From this, two possibilities pop out:

Also at least on the "full" system you can bump debug of the driver to see what it reports anything interesting about the data it sees (if it applies the descriptor fixes, something else...) - see https://github.com/networkupstools/nut/wiki/Changing-NUT-daemon-debug-verbosity
