ESPHome and Home Assistant Compatibility

This hardware device is designed to be compatible with as many common software platforms and hardware systems as possible. GGreg20_V3 is compatible with any of the following systems: Arduino, ESP8266, ESP32, STM32, Raspberry Pi, ESPHome, Home Assistant, Tasmota, MicroPython, NodeMCU, Node-RED and many others. All you need to connect the GGreg20_V3 is a system with a pulse counter on the GPIO and a timer to measure time.

GGreg20_V3 compatible firmware for Flipper Zero

If GGreg20_V3 is used with a J305 Geiger tube, no changes are required at all, i.e. you can simply compile this example. In other cases (for example, if GGreg20_V3 is used with an SBM20 tube), you need to change the conversion factor for the tube from 0.0081 to the appropriate one (for SBM20 - 0.0057) before compiling the firmware in the source code of this example.
