October 3, 2025, Kyiv — IoT-devices LLC is pleased to announce the official release of the new external component, ggreg20_v3, for the ESPHome smart home platform. 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.
