Hello,
I just wanted to confirm that the experimental liebert-hid subdriver is
working correctly for me. I also tested it by uncommenting some lines,
and I thought someone might be interested so here's what I got with the
upsc command:
--------
battery.charge: 100
battery.runtime: 600
battery.type: PbAc
battery.voltage: 13
battery.voltage.nominal: 12
driver.name: usbhid-ups
driver.parameter.pollfreq: 30
driver.parameter.pollinterval: 2
driver.parameter.port: auto
driver.version: 2.2.1-
unmapped.ups.powersummary.capacitygranularity1: 10
unmapped.ups.powersummary.capacitymode: 2
unmapped.ups.powersummary.designcapacity: 100
unmapped.ups.powersummary.flowid: 1
unmapped.ups.powersummary.imanufacturer: 3
unmapped.ups.powersummary.iproduct: 1
unmapped.ups.powersummary.powersummaryid: 1
unmapped.ups.powersummary.rechargeable: 1
ups.load: 25
ups.mfr: LIEBERT
ups.model: PowerSure Personal XT
ups.productid: ffff
ups.status: OL
ups.vendorid: 06da
--------
Some comments:
a) The battery.type attribute is indeed a string, as Charles Lepple
guessed in the commented-out code (PbAc = lead acid).
b) The voltage (both nominal and real) is wrong, but not by a factor of
10 as Charles mentioned on the driver: I have 220 volts nominal here,
and so probably did Alain Williams, who first reported this last year,
since he's from the UK according to his email address. I measured the
real voltage with a voltmeter and I got 213 volts here both for the UPS
input and for the UPS output.
c) I can confirm that the ups.load value goes up a little when running
on battery (it went from 25 to 35). No big deal. On the other hand, the
battery.voltage attribute went down from 13 to 12 when on battery.
d) I don't know what to make of the unmapped attributes, but I don't see
a way to get the UPS to turn the load off during shutdown. I find the
unmapped.ups.powersummary.capacitymode attribute intriguing, though.
e) I don't know if this is of any importance to NUT, but in case anyone
cares let me point out that this UPS does not have a voltage stabilizer
built-in.
f) The battery.runtime value is reasonably accurate (estimated in seconds).
g) I have replaced the SHUTDOWNCMD with the following custom script in
order to hibernate the system instead of shutting it down. It seems to
work for me on CentOS 5.1:
--------
#!/bin/bash
echo disk > /sys/power/state
sleep 10
service ups start
