ESP32 E-Paper Weather Display
One of the most popular open-source e-paper weather station projects, with nearly 6,000 GitHub stars. It pairs an ESP32 microcontroller with a 7.5" Waveshare e-paper display (800x480) to show current weather, 5-day forecast, hourly outlook graph, and indoor temperature/humidity from a BME280 sensor.
Key Features
- Ultra-low power: ~14μA in deep sleep, ~83mA during refresh (~15s)
- Long battery life: 6–12 months on a 5000mAh battery at 30-minute update intervals
- Customizable: Multiple languages, units, time/date formats, AQI scales, and personalization options
- USB-C charging: Built-in battery monitoring with the FireBeetle 2 ESP32-E
Supported Displays
- Waveshare 7.5" e-paper V2 (800x480, B/W) — recommended
- Waveshare 7.5" e-paper (B) (800x480, Red/Black/White)
- Good Display GDEY075T7 and GDEY075Z08
