Geiger counter Rad Pro: Home assistant Integration

Hello everyone

First of all, thanks for RadPro – it’s an impressive project and exactly the kind of open firmware many of us were hoping for.

I’d like to share an idea and ask a few questions that might be interesting not only for me, but for many Home Assistant and smart-home users.

Idea: Simple Home Assistant integration via USB

It would be amazing to have a native Home Assistant integration for RadPro, focused on simplicity:

Connect a Geiger counter (for example Bosean FS-5000)

Use the built-in USB port only

Plug it directly into a computer or device running Home Assistant (PC, NUC, VM host, etc.)

Home Assistant reads live radiation data (CPM, µSv/h, tube info, timestamps, etc.)

Display everything as standard HA sensors, with history, automations, alerts, dashboards

No ESPs, no Wi-Fi bridges, no additional hardware – just USB + RadPro + Home Assistant.

Motivation

Right now, most guides and solutions I can find are:

very old

extremely complex

based on custom hardware, ESP32s, pulse counting, or Linux-only setups

difficult to reproduce for non-experts

Home Assistant users usually expect:

“Plug it in, add an integration, done.”

RadPro already feels like the perfect foundation for this.
