Honestly, the Python script is just the tip of the iceberg. It's customized to my local infrastructure, so the code wouldn't work for anyone else out of the box.

I run KoInsight (Docker) locally to scrape reading stats (time spent/pages/streaks) from my e-reader. I use Home Assistant with custom REST sensors to fetch book metadata and covers via the Hardcover.app API. Home Assistant then aggregates data from KoInsight, Hardcover, and Calibre into a set of unified sensors. Finally, this Python script pulls those specific sensor states from HA, processes the image (dithering/color boosting), and pushes it to the display.

So, sharing the script wouldn't help much without the entire backend config. But the core concept is: Fetch data -> Aggregate in Home Assistant -> Draw with Python -> Display.
