Get readings from an Airthings.com Wave BTLE Radon detector

Project description

# Get Readings from an Airthings Wave and publish to MQTT server

[Airthings](http://airthings.com) 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

```Python
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:
```python
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
```
