A Micropython-based tool for the ESP32 microcontroller to read out a RadonEye sensor using BTLE. Radon level readouts are sent to a HomeMatic system via the web API.
- Copy
config_template.jsontoconfig.json, adjust parameters. - Copy config file to ESP32, copy
btle_reader.pyto ESP32 asmain.py - Reboot ESP32, check serial output to ensure everything is working.
| Parameter | Default value | Description |
|---|---|---|
| ssid | SSID | WiFi SSID |
| pass | PASS | WiFi password |
| radoneye_addr | AA:BB:CC:DD:EE:FF | Radoneye BT MAC address |
| radoneye_addr_type | 1 | Radoneye BTLE address type (1 for RadonEye, 0 for spoofer) |
| readout_interval | 20 | Radon readout interval in seconds |
| homematic_addr | http://0.0.0.0/addons/xmlapi/statechange.cgi?ise_id={ise_id}&new_value={radon} | HomeMatic web API address |
| homematic_ise_id | 12345 | HomeMatic Radon ISE ID |
| reset_timer | 24 | Interval for automated ESP32 reboot in hours (set to 0 to disable) |
The repo contains a utility named blte_spoofer.py, which can be used to imitate RadonEye behavior using another ESP32 for debugging.
To use it, simply copy it to another ESP32 as its main.py.
Important: to connect to it, make sure to set the BTLE address type in the reader's config file to 0.
