Liebert / GXT5-8000IRT5UXLE

[georgelza]

hi hi all,

how do we get a unit added to be supported list: GXT5-8000IRT5UXLE

sudo nut-scanner -U
[sudo] password for pi:
Scanning USB bus.

Which NUT version? Where are the debug logs? Did you try directly probing with a driver (e.g. usbhid-ups or some other)?

[georgelza]

total noob here, so excuse.

sudo nut-scanner --version
[sudo] password for pi:
Network UPS Tools - 2.8.1

can you direct me how to get to the logs, where are they stored.
I asked because scanning supported devices showed other models, but none of the GXE3's or GXT5's

sudo vi /etc/nut/ups.conf
[liebert]
driver = usbhid-ups
port = auto

sudo mkdir /var/run/nut
mkdir: cannot create directory ‘/var/run/nut’: File exists
sudo chown root:nut /var/run/nut
sudo chmod 770 /var/run/nut

sudo upsdrvctl start

Maybe you just have a NUT too old: there is a drivers/liebert-gxe.c in sources, but it was proposed in 2024 and first released as part of NUT v2.8.3. It is however a serial-port driver, so I am not sure nut-scanner would discover the device (it only pokes some Eaton/MGE protocols over serial ports). In this context, the USB connection may be an USB-to-serial adapter on the UPS side, so it would look like /dev/ttyUSB0 and not e.g. a USB HID device on Linux side.

Regarding the more verbose logs, see https://github.com/networkupstools/nut/wiki/Changing-NUT-daemon-debug-verbosity

The Liebert ships with a USB Type A -> USB Type B cable.
A side is into Raspberry Pi, B is into the USB comm port of the inverter.
