ePaper dashboard

A battery-powered e-paper dashboard that shows data from Home Assistant: six tiles with values or weather icons, warnings from sources such as NINA, and the battery state. It runs MicroPython on an Adafruit Feather ESP32-S3 with a Waveshare 4.2” display, sleeps between updates and lasts several weeks on a 2000 mAh battery.
