Cyber Power LX1500GU incorrect output voltage reading

[JasonNaughton]

Working on FreeBSD 11.4, managed to configure ups.conf, so that my Cyberpower 1500 UPS was reporting but unfortunately some of the values are a bit off:

upsc cyberups

battery.charge: 100
battery.charge.low: 10
battery.charge.warning: 20
battery.mfr.date: CPS
battery.runtime: 1650

output.voltage: 140.0
ups.beeper.status: enabled
ups.delay.shutdown: 20

ups.status: OL
ups.test.result: No test initiated
ups.timer.shutdown: -60
ups.timer.start: -60
ups.vendorid: 0764

My, I'm sure the output voltage is 120 not 140.

Also noticed that ups_upslog values are not reporting properly:

cat /var/log/nut/ups.log

Did a

/usr/local/libexec/nut/usbhid-ups -DDDDD -a cyberups 2> /tmp/ouput

Found the lines which the UPS was reporting:

see #581 and other issues tagged CyberPower. The HID report descriptors are broken.

What Vendorid and Poductid does your UPS report?

[JasonNaughton]

Unfortunately I disconnected the UPS from the server as I wasn't getting any response a while back. Sorry I can't give you much information on it now.

Can you please run the driver with higher debug verbosity (3 or more) so it dumps content of the USB Report Descriptors (lots of hex) and interpretation (Path lines) annd copy that log here?

Are you in position to build and run current NUT from github master? @flashydave proposed some fixes for broken CPS descriptors, maybe your issue is already resolved.

[arcenik]

Hi,

Here is the debug log from the Debian package driver.

/lib/nut/usbhid-ups -DDDDD -a cyberpower 2>&1 | tee /tmp/nut-driver-debug.log

nut-driver-debug.log

I've compiled nut from the source but it does not work, do I need some lib or parameter in configure call ?

   0.005749     Can't connect to UPS [cyberpower] (usbhid-ups-cyberpower): Connection refused
   0.005821     Found 1 UPS defined in ups.conf

[jimklimov]

Thanks, the latter looks like a message from upsd while the driver is not started?

[darsys]

I have same issue. I wanted to share my information just so this issue is well documented. Everything works properly except the output voltage, as far as I can tell.

Version: Generic HID driver 0.41 (2.7.4)

Excerpt from usbhid-ups:

0.653344 Entering libusb_get_report
0.654006 Report[get]: (3 bytes) => 12 7c 00
0.654049 PhyMax = 0, PhyMin = 0, LogMax = 142, LogMin = 136
0.654091 Unit = 00f0d121, UnitExp = 7
0.654125 Exponent = 0
0.654159 hid_lookup_path: 00840004 -> UPS
0.654194 hid_lookup_path: 0084001c -> Output
0.654230 hid_lookup_path: 00840030 -> Voltage
0.654295 Path: UPS.Output.Voltage, Type: Feature, ReportID: 0x12, Offset: 0, Size: 16, Value: 140

Hex 7c = 124 but the value reported is 140.

Attached is the complete log of my sudo /lib/nut/usbhid-ups -DDDDD -a cyberpower run
cyberpower_usbhid.log

PR #2718 is presumed to fix the broken CPS input/output voltage reports discussed in this issue (although it did not focus on cases of "voltage too high" like most of the reports here). That might have been or not been addressed collaterally.
