Nice project. The $15 price point is genuinely impressive for something like this.
I've been curious about e-ink displays for a while but haven't taken the plunge. What's the refresh rate like in practice? And does it actually help you notice interesting posts you'd otherwise miss, or is it more of a fun desk decoration?
Why not using MQTT? A Lambda that fetch new comments from HN, parse them into Markdown and push into MQTT; the ESP only needs to subscribes a topic on MQTT and render the messages.
Satisfying to see all the payload request and response sizes in bytes not kb.
Q: the display just starts at 0 and increments comment id by 1 every 10 seconds. Has the device caught up to latest? If you power cycle it, do you have to run through all historical comments?
This is awesome. I've been meaning to check out WireGuard for some time, and this project has been inspiring for me. Thanks!

The refresh rate must be something like 20fps when scrolling the text of long posts. I’m not sure and haven’t measured.
While I’m working I glance at it from time to time and get a sense of the wide breadth of conversations going on at any moment.

The zero is just a magic number to indicate grab the newest. So it’s just showing the most recent comments.
