Documentation

Get Readings from an Airthings Wave and publish to MQTT server

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.

Limitations

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

API

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

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):

Example

From main.py:

    c = sys.argv[1]

    atw=airthingswave.AirthingsWave_mqtt(c)

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