Does this do/can it be used for keeping track of bicycle maintenance? Mostly which components are used (tires, brake pads,…) and when maintenance was done and so on?

Would love to see it.

Here’s mine from the Paperless compose.yml (non functional):

  webserver:
    image: ghcr.io/paperless-ngx/paperless-ngx
    [...]
    labels:
      - homepage.group=Productivity
      - homepage.name=Paperless
      - homepage.icon=paperless.png
      - homepage.href=https://[LOCAL URL]
      - homepage.description=Document Management
      - homepage.widget.type=paperlessngx
      - homepage.widget.url=http://[PAPERLESS IP:PORT]
      - homepage.widget.key=[PAPERLESS API TOKEN]

And here’s the error from Homepage frontend:

    API Error: Unknown error
    URL: http://[PAPERLESS IP:PORT]/api/statistics/?format=json
    Raw Error:
    {
        "errno": -110,
        "code": "ETIMEDOUT",
        "syscall": "connect",
        "address": "[PAPERLESS IP]",
        "port": [PAPERLESS PORT]
    }

I don’t think it’s you. The paperless widget stopped working for me recently after it had been fine before. Similar setup to yours.

It bothered me a little but since the widget isn’t actually very useful to me I didn’t care to invest more time to get to the bottom of it.
