E-Paper Dashboard without coding | Xiao E-Paper Display and TRMNL Firmware

Published at : 23 Dec 2025

In this video, I show you how to turn the Seeed Studio Xiao 7.5-inch E-Paper Panel into a clean, always-on smart home dashboard using the open-source TRMNL firmware. You'll see what's in the box, how the hardware works, and how to set up and customize your own dashboard using TRMNL's web editor.

This setup is low-power, minimal, and can display useful data like weather, reminders, calendar events, or anything you pull from an API or Home Assistant.
