Airthings makes a BTLE Radon detector called "Wave". This is an executable intended to be called periodically from Cron or some other scheduler to publish readings to an MQTT server.

This application doesn't implement 'find' as provided in the example at https://airthings.com/raspberry-pi/

This is just a python API with a main loop that I happen to use in my own Home-Assistant setup. If you're looking for a plug and play solution, consider balena-airthingswave - @renemarc has created his appliance package using airthingswave-mqtt.

class AirthingsWave:
    def __init__(self, config_file):

Class instantiation requires a path to a config file in YAML format.

mqtt:
  broker: 192.168.30.18
  port: 1883
  username: 
  password: 

waves:
  - name: "basement-radon"
    addr: 98:07:2d:43:4d:ff

Before taking a reading, you should:

def ble_connect(self, addr):

Then you can:

def get_readings(self, p):
def publish_readings(self, name, readings):

From _main_.py:

c = sys.argv[1]

atw = airthingswave.AirthingsWave_mqtt(c)

count = len(atw.waves)
if count > 0:
    i = 0
    while i < count:
        handle = atw.ble_connect(atw.waves[i]["addr"])
        r = atw.get_readings(handle)
        atw.ble_disconnect(handle)
        atw.publish_readings(atw.waves[i]["name"], r)
        i = i+1

return True
