Key Facts
- Chip: ESP32 (FireBeetle 2 ESP32-E recommended)
- Display: 7.5in 800x480 e-paper
- Sensor: BME280 indoor
- Data: OpenWeatherMap API
- Power: LiPo + deep sleep
About This Project
This build pulls forecast data from the OpenWeatherMap API and renders a dense, nicely laid-out dashboard (current conditions, hourly graph, daily forecast, air quality) on a 7.5in 800x480 e-paper panel. The ESP32 wakes, fetches, draws and goes back to deep sleep, so a single LiPo lasts a long time. An indoor BME280 adds room temperature and humidity. The README documents wiring, a DESPI-C02 or Waveshare driver board, and a 3D-printable stand, which makes it one of the most reproducible e-ink weather builds on GitHub.
