From the project

Rework of the https://github.com/ecocurious2/MultiGeiger/ codebase, directly on the latest ESP-IDF

A ground-up C rewrite of the MultiGeiger radiation sensor firmware, ported from Arduino / PlatformIO to native ESP-IDF 6.0. Runs on eleven ESP32 / ESP32-S3 / ESP32-C5 board variants with a wide selection of optional environmental, particulate, noise, and ambient-light sensors. Uploads to nine public back-ends and publishes to MQTT (with Home Assistant Discovery) and remote syslog.
