Home Assistant displays a lovelace view of the dashboard which is then rendered to a JPG-image. The Inkplate wakes up every 20 minutes from it’s energy-saving deep sleep, retrieves the image, sends an MQTT message and goes back to sleep again. Thanks to the nature of the e-ink display, the rendered image stays on the screen.
If you’re interested in this project I highly recommend you check out my write up linked below. In this article I go in detail about the architecture, all the components used and how I set everything up. As a contribution to open source I made my code available on Github. It’s all in this multi-page article linked here, feel free to dig in and leave a comment. 🙂
At this point I would like to thank everyone joining the discussion on Reddit and especially everyone beeing so generous to give anonymous rewards. You guys really had an impact on my little blog here, as you can see from these metrics! 🙂
