A battery-powered E-Paper weather station using ESPHome and Home Assistant.

A low-power ESP32-based battery monitor and weather display built with ESPHome and designed for easy integration with Home Assistant. This project turns a WeMos LOLIN D32 board into a smart, ultra-efficient sensor node that reads and displays battery voltage, charge status, environmental data, and weather forecasts on a Waveshare ePaper display.

An e-ink photo frame that runs forever.

🔧 Build a modular, power-aware firmware system for STM32 with CLI dashboard, logging, and sensor abstraction for efficient embedded solutions.
