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.

The snarky answer is that MQTT doesn't require the author's UDP to AWS Lambda gateway SaaS⁰.

I did find MQTT flavors that support UDP but neither MQTT/UDP nor MQTT-SN seem concerned with WireGuard-level security.

Fair point that yes I’m eating my own dog food here. And I’ve been called a robot enough times maybe I should keep track.

To the question, UDP is easier on a battery than MQTT.

To be clear I understand you are not a robot, but the article reads more as LLM generated especially toward the end which is why I said "AI-assisted".
