This component significantly simplifies the integration of GGreg20_V3 Geiger counter-based radiation monitoring sensors into any system running ESPHome.

Seamless Integration of Radiation Monitoring

The ggreg20_v3 component is designed for smart home enthusiasts and developers who seek to add ionizing radiation monitoring capabilities to their devices.

It provides a comprehensive set of data points essential for complete environmental control, including:

  • Radiation Power (μSv/h)
  • Equivalent Absorbed Dose (μSv/h)
  • Total Accumulated Dose (μSv)
  • Counts Per Minute (CPM) over the defined measurement period
  • Instantaneous pulse count value
  • System Status (alerts for danger, normal levels, or sensor errors)

This component autonomously handles all complex calculations, including dead time correction for the tube, delivering all necessary data for seamless automation within Home Assistant.

Key Advantage: Cross-Controller Compatibility

The core value of the component developed by IoT-devices LLC lies in its versatility. The ggreg20_v3 component is cross-controller compatible, supporting any microcontroller that runs ESPHome (including ESP32, ESP8266, Raspberry Pi Pico W, and others).

This eliminates the need to write individual code for different hardware platforms, allowing users to rapidly integrate radiation monitoring regardless of the specific controller used for their projects.

“We built ggreg20_v3 with the ESPHome community in mind. Our goal is to make environmental monitoring as accessible and reliable as possible by providing a single, flexible solution that works across all supported controllers,” commented IoT-devices LLC representatives.

How to Get Started

The ggreg20_v3 component is available as an external Git component.

To install: Add our repository to your ESPHome configuration and follow our detailed documentation.

IoT-devices LLC welcomes the community to test, provide feedback, and contribute to the component’s development.

But after users started making projects for RPi with GGreg20_V3, and after Tom’s Hardware wrote about a project using Pico W, we also made our own full-featured configuration example.

The main features of this example configuration compared to our previous ones:

  • two types of tubes are taken into account and supported: J305 and SBM20. The user can switch between the two types of tubes with a convenient selector to calculate the values directly during operation, via the frontend, for example, through the Home Assistant dashboard widget.
  • the Geiger tube internal noise compensation mode was taken into account and offered. This mode can also be switched directly during operation via the frontend.
  • the calculation of internal noise compensation also takes into account the situation when the number of pulses is not enough to compensate. In this case, no compensation is performed. Please note that our example contains the coefficients provided by Geiger tube manufacturers: for J305: 0.2 pulses per second; for SBM20: 1 pulse per second.
  • the configuration creates a separate text sensor that automatically shows the current status according to the radiation level: normal / warning / danger.
  • the text status sensor also supports the situation when no pulses are received from the GGreg20_V3 module. In this case, this sensor will have the value “sensor error”.
