The RadonEye RD200 is tightly coupled with the mobile app and this is basically useless for home automation. This is a very basic app to read the value using the tinygo bluetooth library and publishes the radon value to an MQTT broker.
Usage of ./radoneyebt:
-L string set the log level (debug, info, warn, error) (default "info")
-b string MQTT broker endpoint (default "tcp://iot.eclipse.org:1883")
-m string The MQTT topic root (default "airmeter/radon")
-r string RX Level Characteristic UUID (default "00001525-1212-efde-1523-785feabcd123")
-s string Service UUID (default "00001523-1212-efde-1523-785feabcd123")
-t string TX Level Characteristic UUID (default "00001523-1212-efde-1523-785feabcd123")E Camden Fisher
