## What it is
An Arduino/ESP32 firmware project that fetches weather data from the OpenWeatherMap API and renders it on Waveshare ePaper (e-ink) displays in various sizes. It is distributed as an Arduino library with examples for multiple screen sizes.

## Use cases
- display weather forecast on an e-ink screen
- build an ESP32 e-paper weather station
- show OpenWeatherMap data on a Waveshare 7.5 inch display
- low-power always-on weather dashboard
- arduino epaper weather display project

## When to choose
- you have an ESP32 and a Waveshare ePaper display and want a ready-made weather display
- you want an Arduino library with examples for multiple screen sizes
- you prefer a standalone firmware with no server required

## When to avoid
- you need a different weather provider than OpenWeatherMap without code changes
- you use non-Waveshare ePaper hardware that GxEPD2 does not support
- you want a web or mobile weather app rather than embedded firmware

## Facets
- artifact type: application
- maturity: active
- function: http-client, json, graphics, sdk
- domain: iot, weather, embedded-systems, hardware
- platform: embedded, iot, cpp
- tags: esp32, epaper, e-ink-display, openweathermap, arduino, waveshare, weather-station, u8g2
