esp-radiation-counter-gateway

Bridges GGreg20_V3, RadiationD-v1.1 (CAJOE), etc. radiation detectors to MQTT. Provides MQTT device for easy HomeAssistant integration.

Two-page display with scrolling by FLASH button.

Wiring

ESP8266 is capable of providing 3.3V (3V Pin) and 5V (VU Pin) to power the detector board itself, but you can separate voltages if you like, just remember to connect a shared ground.

Signal should go to pin D2.
