Hi all,

I’m trying to integrate a PowerWalker On-Line 1000VA UPS with Home Assistant Green using the official Network UPS Tools (NUT) add-on.

I’ve configured everything correctly in the add-on:

devices:

  • name: powerwalker
    driver: usbhid-ups
    port: auto
    config: []

usb: true

users:

  • username: nutuser
    password: VerySafePassword123!
    instcmds:
    • all
      actions: [set]

mode: netserver
shutdown_host: true

But every time I start the add-on, I get this error:

libusb1: Could not open any HID devices: insufficient permissions on everything
No matching HID UPS found
Driver failed to start (exit status=1)

I confirmed the UPS is detected as /dev/usb/hiddev0 and shows up in the hardware list, but NUT still can’t access it. I’m on Home Assistant OS 15.2 (aarch64 / Green).

I understand HA OS is sandboxed, but is there any way to get NUT access to USB HID on Green? Maybe via udev overrides, privileged mode, or a custom build?

Would love any help or creative ideas — switching to a supervised install isn’t ideal for me.

Thanks in advance!

Does it work with driver blazer_usb or nutdrv_qx?
Those are mentioned in the NUT documentation for some Powerwalker UPS.
