## What it is
ESPTimeCast is firmware for a WiFi-connected LED matrix clock and weather display built on ESP8266/ESP32 with MAX7219 displays. It provides NTP time sync, live OpenWeatherMap weather data, custom messages and timers, a browser-based configuration interface, and OTA firmware updates.

## Use cases
- build a desk clock that shows time and weather on an LED matrix
- flash firmware to an ESP32 or ESP8266 from the browser without Arduino IDE
- display custom messages or reminders on a MAX7219 LED matrix
- set up a WiFi weather station with OpenWeatherMap data
- update device firmware wirelessly over the air
- make a minimalist NTP-synced clock for home or office

## When to choose
- you have an ESP8266/ESP32 board and a MAX7219 LED matrix and want a polished clock/weather display
- you want browser-based flashing and configuration with no Arduino IDE setup
- you need OTA updates and a web UI for managing the device

## When to avoid
- you need a different display type than MAX7219 LED matrices
- you want a general-purpose weather station with sensors rather than API-based weather
- you require a commercially licensed product (license is non-standard)
