Greencell Micropower 600 not shutting down, First supported language ID: 0x9 (please report to the NUT maintainer!)

[tylkomat]

The UPS looks to be using working with the blazer_usb driver. My current ups.conf has just basic values:

maxretry = 3
xretry = 5
pollinterval = 5

[greencell]
  driver = "blazer_usb"
  port = "auto"
  langid_fix = 0x409

upsc gives the following output

The different status events are properly reported and my connected raspberry pi shuts down as expected, but the UPS does not shut down.
When I issue the upsdrvctl shutdown command I get the following output, but nothing happens:

upsdrvctl shutdown
Network UPS Tools - UPS driver controller 2.7.4

instcmd(shutdown.return, [NULL])
instcmd: command [shutdown.return] handled
Shutting down in 30 seconds

Connecting the UPS to my windows notebook and having the Upsilon 2000 software installed I can properly shut down the UPS.

I also used the nut_scanner command and got the following output:

[nutdev1]
        driver = "nutdrv_atcl_usb"
        port = "auto"
        vendorid = "0001"
        productid = "0000"
        product = "MEC0003"
        vendor = "MEC"
        bus = "001"

Using that config I get errors that many properties are not supported by that driver (vendorid, productid, bus and vendor), and talking to the driver I get the following output:

nutdrv_atcl_usb -a nutdev1 -DDDD -u root
Network UPS Tools - 'ATCL FOR UPS' USB driver 1.1 (2.7.4)

Note the line First supported language ID: 0x9 (please report to the NUT maintainer!)

I also tried the other langid_fix values that I found, but the result is the same.

Any idea what else I can try?

[jimklimov]

Please check if similar settings with nutdrv_qx would work with this UPS, at all or better? It is supposed to supercede the Qx protocols earlier written in several drivers.

[tylkomat]

@jimklimov thanks for the hint. That worked. Using the settings that nut-scanner gave me, except switching to nutdrv_qx works.

[nutdev1]
        driver = "nutdrv_qx"
        port = "auto"
        vendorid = "0001"
        productid = "0000"
        product = "MEC0003"
        vendor = "MEC"
        bus = "001"

[tylkomat]

If I would be able to disable the beeper then I would have achieved all my goals. beeper.toggle command works, but the driver settings alarm_control = disabled and battery_alarm = disabled don't do anything.

[jbaumann]

@tylkomat, I just bought the exact same UPS for my RPi, it shows the same vendorid and productid when checking with lsusb, but the nutdrv_qx driver doesn‘t recognize the UPS when I use the configuration you posted (it works with the blazer_usb driver).
Did you change anything to get it to work?
My ultimate goal is to be able to shut down the UPS from the RPi.
What could I try?

[jimklimov]

@tylkomat : just for clarification, with nutdrv_qx does the shutdown also work as expected? Did you build NUT from recent source or used a packaged 2.7.4 when trying that out (possibly the build @jbaumann is using does not have the modernized features yet)?

[tylkomat]

I used the packaged 2.7.4. I think it was shutting down correctly. I'm unfortunately not near that device to try it out. I may be able to give that information in some months.

[jbaumann]

I have now retested with a fresh installation of Raspbian (Bullseye) and the version 2.7.4-13, and with these versions the configuration given by @tylkomat works without problems. Thank you very much for all the hard work.

[got3nks]

@tylkomat did you get /sbin/upsdrvctl shutdown to work? With my UPS Green Cell 2000V it seems to have no effect.

root@rpi:~# /sbin/upsdrvctl shutdown
Network UPS Tools - UPS driver controller 2.7.4
Network UPS Tools - Generic Q* USB/Serial driver 0.28 (2.7.4)
USB communication driver 0.33
Using protocol: Q1 0.07
Initiating UPS shutdown
instcmd(shutdown.stop, [NULL])
instcmd: SUCCEED
instcmd(shutdown.return, [NULL])
instcmd: SUCCEED
Shutting down in 30 seconds

But nothing happens, the UPS will stay on.
At the same time I found out the command /usr/bin/upscmd -u <user> -p <password> greencell shutdown.return will instead get the UPS to shutdown in 30 seconds, as expected.

My /etc/nut/ups.conf:

maxretry = 3

[greencell]
        driver = "nutdrv_qx"
        default.battery.voltage.high = 25.60
        default.battery.voltage.low = 20.80
        port = "auto"
        desc = "Green Cell UPS"

[tylkomat]

@got3nks Yes, this config was working for me:

[nutdev1]
        driver = "nutdrv_qx"
        port = "auto"
        vendorid = "0001"
        productid = "0000"
        product = "MEC0003"
        vendor = "MEC"
        bus = "001"
