Hi everyone, first time posting here ;)
I built ESPTimeCast, a WiFi-connected LED matrix clock and weather station using ESP8266/ESP32 + MAX7219, now with Home Assistant integration!
Features highlighted in the demo video:
- Connects to WiFi and gets an IP for Web UI access
- Time + Day of the Week, Date
- Temperature from OpenWeatherMap
- Dramatic Countdown
- Nightscout glucose monitoring
- Custom scrolling messages via Web UI
- Home Assistant messages: temporary notifications that appear over your persistent display message (perfect for alerts like door open, mail delivered, rain starting)
Everything is configurable through the built-in Web UI - no need to touch the code once it’s on your network.

Feedback and suggestions for smart home alerts and custom display messages are welcome!
