We have previously written about how to calculate the coefficients for the SBM20 tube and the J305, tube that come with our Geiger counter module GGreg20_V3 for DIY / IoT projects.
However, in those articles, we focused heavily on the calculation formulas and almost overlooked a very important detail...

We have already made a similar publication for the SBM20 Geiger tube. This time we bring to your attention an article dedicated to the equally popular J305 GM-tube made in China.

Recently, the ESPHome firmware has been changed to prevent the same controller I/O ports from being reused to create different entities.

These updates in ESPHome version 2023.12.0 also affected the examples developed by our company for the GGreg20_V3 Geiger counter ionizing radiation detector module.

According to the user’s request (https://github.com/iotdevicesdev/GGreg20_V3-ESP32-HomeAssistant-ESPHome/issues/2) regarding the repository for GGreg20_V3-ESP32-HomeAssistant-ESPHome, we have made the necessary updates to the configuration YAML file.

Now this example will work properly with the new ESHome configuration validation and you will be able to upgrade to newer versions of ESPHome without any problems.

We also plan to update other repositories with this issue.

An interesting work by experts from the Kyiv Polytechnic Institute describes software methods for analyzing streaming data, in particular, for analyzing radiation pollution.

The article analyzes open data on radiation air pollution in the city Kyiv and visualized the data using analytical tools of the Python programming language.
