Hi,

Wondering if you can help with nut-upsd.

I am not specifying SERIAL env var because it is not needed, but NUT spits out like it's still being sent:

Recreating nut-upsd_app_1 ... done

Here is my docker-compose:

services:
  app:
    image: instantlinux/nut-upsd:latest
    restart: always
    environment:
      PORT: /dev/ttyUSB1
      DRIVER: apcsmart

I "fixed" it by mounting my own ups.conf but this is a bug, as it shouldn't send SERIAL if its not needed or defined. Cheers!

Very weird to hear this: APC is a leading UPS maker and this image has been working for a huge number of users for several years. Can you post your working ups.conf, so I can craft the correct update to entrypoint.sh? Thanks!

timdonovanuk commented

Sure!

[apc-sc450]
    driver = apcsmart
    port = auto
    desc = "apc-sc450"

Maybe all the previous users were using the usbhid-ups driver. My APC model is apc-sc450 and I'm having to use a custom serial to usb cable with the apcsmart driver. Thanks.

New image is posted, do a docker pull to get the update. I also updated the Docker Hub README with info about how to get a list of available drivers and how to get the driver-specific help.
