Changes in ESPHome configuration validation – Pin Reuse validation
01/05/2024 at 17:01 • 0 commentsRecently, 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.

Technical note. How to calculate the conversion factor for Geiger tube SBM20
07/18/2023 at 19:02 • 0 commentsThere are a lot of publications on the Internet on how to convert CPM (Counts per Minute) obtained from a Geiger tube to radiation levels.
However, despite the wide coverage of this topic on various forums and a wide range of examples with code for various programming languages, we had to understand the topic deeper than we wanted to in order to be able to properly calculate the conversion factor for Geiger tube SBM20 from CPM to absorbed dose of radiation μSv/h and configure the conversion in our own products and make an example calculation for everyone.
