[Nut-upsuser] Fwd: contineously receiving the same values

[Matthew Wire]

The software UPSmart 1.5 is the same as I am using in this thread:
http://lists.alioth.debian.org/pipermail/nut-upsdev/2016-November/007248.
html (starts in 2016-August) for the powercool 1500VA USB UPS.  Have not
yet been successful with getting it working with NUT but the symptoms are
the same and you may find some of the debug useful from https://github.com/
mattwire/powercool-ups

If it helps, I can provide additional logging/testing etc.

same error being "Can't chdir to /var/state/ups: No such file or directory"?
if so, ensure that you use Charles' provided "configure" directives, and
then make && make install.

Thanks for sharing your use case, and the rationales behind.
First, the base point is to be able to cancel a timer anytime, from a
command-line, which makes sense (as an extension, the opposite may also be
true, to start a timer lively, without the event coming from upsmon).

I've quickly checked your 2 patches.
The solution seems to me not broad enough for injecting upstream. This
works nice for a single device / UPS setup, but would not make it when
there are more devices, as I get it.

At first sight, I would more see something injecting into the PIPEFN fifo,
i.e. acting the same way upsmon would when calling upssched with the
upsname and the triggering event.
I think that this can be solved more easily with tools like socat or nc,
sending the command directly to the pipe.
For example, to cancel the timer "shutdown-timer" from the upssched-cmd
script, you would:

   echo "CANCEL shutdown-timer" | socat -
UNIX-CLIENT:/var/run/nut/upssched.pipe

Please tell me back if such solution would make it for you.

I also realize that the distributed sample configuration and scripts do not
fully match the doc.
I'll make another round of update for this, still on the same branch.
I would warmly welcome your help to complete the documentation, both with
part of your patches that make sense, along with the above solution if it's
good too.

cheers,
Arno

Do you have a direct link? I found UPSmart-DryContact-V3-4.zip and

I might have been confusing that issue with this comment in the parent thread, 
which seems to be similar underlying hardware repeating the last reading:

https://github.com/networkupstools/nut/issues/307#issuecomment-243364229

The #409 report might have been due to a combination of the auto-detection, 
plus the lack of "vendor magic" from UPSmart.

Re: [Nut-upsuser] contineously receiving the same values

[Marc Kessels]

Hi Charles,


Upsmart version is 1.5, copyright says 2012-2014

the github issue seems a bit worse, since it reports:

 received 10 (85)
   1.158700 read: UPS No Ack

whereas my system reports :

 6.239688 Full update...
   6.239776 send: Q1
   6.261270 received 47 (40)
   6.261371 read: (234.0 000.0 234.0 012 49.9 27.4 29.0 1000

but it keeps repeating the last line, so I am not getting any update.

I'll give the wireshark sniffer a try, to see if I can find a solution 
there.


thanks,

marc

Assuming you have the original manufacturer-provided monitoring program, a 
capture of it 'talking' to the device could help diagnosing the problem.

Is there a way to sniff the USB communication of the UPSmart?

[Nut-upsuser] contineously receiving the same values

[Marc Kessels]

Hello,

I'm trying to get an energenie EG-UPS-033 
(http://energenie.com/item.aspx?id=8087) to work with nut. It standard 
comes with linux software (UPSmart), which shows the input/output 
voltage, load level, input frequency. and battery  and case temperature. 
The values change about every second. The selected monitor mode in this 
tool is Mega(USB). The bad thing of this tool that it requires an X 
server, and does not provide a command line version.


with NUT, I am able to connect to the UPS using the  blazer_usb and 
nutdrv_qx. However, the reported values are constant, and only change if 
I run the UPSmart tool (It can run in parallel). What can I do to get 
NUT to receive updated values?

I already tried the various subdrivers, and langid_fix , but to no avail.

Is there a way to sniff the USB communication of the UPSmart?


thanks a lot for your help,
Marc

here my details:

 *

   OS name and version,: ubuntu 14.04.1 64bit

 *

   exact NUT version: 2.74

 *

   NUT installation method: from source tarball, package or Subversion,
   compiled from source tarball

 *

   exact device name and related information (manufacturing date, web
   pointers, …), energenie EG-UPS-033
   (http://energenie.com/item.aspx?id=8087)

 *

   complete problem description, with any relevant traces, like system
   log excerpts, and driver debug output. You can obtain the latter
   using the following command, as root and after having stopped NUT:
