This weather station displays real-time weather data, forecasts, and temperature trends on a 5.79-inch e-paper display. It features adaptive highlighting of key weather metrics, power-efficient deep sleep mode, and user-configurable parameters. The project requires an OpenWeatherMap API key, WiFi credentials, and location coordinates. Easy setup via Arduino IDE with detailed instructions available on GitHub.

Key Features

• Real-time Weather Data: Displays current temperature, humidity, pressure, and weather conditions
• Weather Forecast: Shows upcoming weather forecast with icons and temperatures
• Temperature Graph: Visual representation of temperature trends over the next 24 hours
• Adaptive Display: Automatically highlights significant weather metrics (UVI when high, precipitation when present, wind speed when significant)
• Pixel perfection: Carefully rendering a font creates a beautiful appearance.
• Power Efficient: Utilizes deep sleep functionality to maximize battery life
• Configurable Refresh: Weather data updates at user-defined intervals
• Error Recovery: Automatic retry mechanism if API calls or connectivity fail

Setup Requirements

• WiFi network credentials
• OpenWeatherMap API key (free tier compatible)
• Geographical coordinates for your location
• Arduino IDE with ESP32-S3 support and required libraries
