Hello, I am trying to connect to my Liebert GXT4 UPS using NUT. I have been able to connect by using information from the following post.
https://alioth-lists.debian.net/pipermail/nut-upsuser/2017-June/010682.html I am running on a Raspberry PI 3 Model B Rev 1.2 pi@vpn01alp:~ $ cat /etc/os-release PRETTY_NAME="Raspbian GNU/Linux 9 (stretch)" NAME="Raspbian GNU/Linux" VERSION_ID="9" VERSION="9 (stretch)" VERSION_CODENAME=stretch ID=raspbian ID_LIKE=debian HOME_URL="http://www.raspbian.org/"; SUPPORT_URL="http://www.raspbian.org/RaspbianForums"; BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"; I installed using apt-get install nut nut-server nut-client My configuration is as follows pi@vpn01alp:~ $ tail /etc/nut/ups.conf # the -h option and/or read the driver's documentation. # Set maxretry to 3 by default, this should mitigate race with slow devices: maxretry = 3 [Liebert] productid=0000 driver = usbhid-ups port = auto desc = "Liebert" I also added the following to /lib/udev/rules.d/62-nut-usbups.rules # Liebert GXT4 - usbhid-ups ATTR{idVendor}=="10af", ATTR{idProduct}=="0004", MODE="664", GROUP="nut" That didn't work so I changed permissions using the following pi@vpn01alp:~ $ lsusb Bus 001 Device 004: ID 10af:0000 Liebert Corp. UPS Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp.

It doesn't appear to be complete or accurate. pi@vpn01alp:~ $ upsc Liebert Init SSL without certificate database battery.charge: 100 battery.charge.low: 20 battery.charge.warning: 0 battery.type: PbAc battery.voltage: 0.0 battery.voltage.nominal: 0.0 device.mfr: Emerson Network Power device.model: Liebert GXT4 device.serial: 1718700042AFB93 device.type: ups driver.name: usbhid-ups driver.parameter.pollfreq: 30 driver.parameter.pollinterval: 2 driver.parameter.port: auto driver.parameter.productid: 0000 driver.parameter.synchronous: no driver.version: 2.7.4 driver.version.data: Belkin/Liebert HID 0.17 driver.version.internal: 0.41 ups.mfr: Emerson Network Power ups.model: Liebert GXT4 ups.productid: 0000 ups.serial: 1718700042AFB93 ups.status: OL CHRG ups.vendorid: 10af I'm not sure how to find the version of NUT I'm running. I found the changelog (/usr/share/doc/nut) and I'm guessing this is my issue. It appears the latest comment was from 2017. nut (2.7.4-5) unstable; urgency=medium * debian/control: Build-depends against asciidoc-dblatex, Recommends are not pulled automatically by the buildd (Closes: #851015) -- Laurent Bigonville <[email protected]> Wed, 25 Jan 2017 09:14:10 +0100 I am guessing I need to install a newer version. Is this correct? Thanks, Matt
