PowerWalker VI 1000 LCD fails to show load when connected to Home Assistant NUT Add-On

[oywino]

It shows everything else, except load.
But when the same UPS is connected to a QNAP NAS, then it also shows load, so obviously the UPS itself delivers that value.
Here are my details:

Here's my YAML config:

users:
  - username: xxxxxxxx
    password: yyyyyyyy
    instcmds:
      - all
    actions: []
devices:
  - name: myups
    driver: nutdrv_qx
    port: auto
    config:
      - vendorid = "0665"
      - productid = "5161"
mode: netserver
shutdown_host: false
log_level: debug
i_like_to_be_pwned: false
leave_front_door_open: false
list_usb_devices: true

And here's the log:

I have tried the usbhid-ups and blazer_usb drivers. With the usbhid-ups the NUT Add-On crashes and the blazer_usb driver gives exactly the same result as the nutdrv_qx.
I have also tried adding a pollinterval but any value result in a never ending connection loop.

Why is my QNAP NAS built in OS NUT Driver able to fetch load data while the Home Assistant NUT Add-on isn't?
I can't think of any more parameters to tweak. Please help.
My HW is Home Assistant Yellow running HAOS 2024-10-4 with the latest NUT add-on and integration.

I am not sure which version of NUY is used by QNAP, but here "2.8.0" is mentioned. There was some development since, in nutdev_qx and blazer drivers, IIRC, that could have them show more data in 2.8.2 (latest NUT release).

Wiki here has a community article about building a custom HA plugin (stock one takes a package from debian-ish distro, and those lag behind - especially stable repos, by design).

Many thanks for your reply. Perhaps I'd be in luck that someone else also had the same problem and already did custom HA 2.8.2 build ? 😊 (and that he or she would offer it as a pull request in the official repo)

Can't speak to that. Maybe @aquette knows more, might have tinkered with HA?..
