wave-reader 0.0.4

Unofficial package for Airthings Wave communication.

Summary

This is an unofficial Airthings Wave library designed to provide software developers a more developer-friendly library for BTLE handling for Airthings Wave devices. This library wouldn't be possible without the documentation and scripts available by Airthings. I hope to continue making updates through Airthings continued open-source contributions.

This library uses bleak as a dependency instead of bluepy for platform cross-compatibility and support for asynchronous operation.

This project is currently in alpha state.

Goals

These are the goals for this project, in no particular order:

• Support platform cross-compatibility. Windows, Mac and Linux.
• Support WavePlus, Wave (Version 2) and Wave Mini devices.
• Support operation across multiple devices asynchronously.
• Code testing, linting, type hinting, formatting and coverage reporting.
• Discover all Wave devices or inherit WaveDevice class for sensor readings.
• Add battery life support.
• Implement reconnection logic for BTLE client.
• Support other devices like Wave (Version 1) and more.

Requirements

In Ubuntu Linux, make sure you have libglib2.0-dev and bluez installed:

sudo apt-get install libglib2.0-dev bluez -y

In theory, other platforms (Windows, Mac) are supported by using bleak as a dependency, but open a ticket if you run into any issues.

Installation

You can install the library by running:

pip install wave-reader

Example Usage

There are various concrete examples available in the examples directory. This includes CLI interaction and other scnearios that demonstrate API usage.

import asyncio

from wave_reader import discover_devices

if __name__ == "__main__":
    # Event loop to run asynchronous tasks.
    loop = asyncio.get_event_loop()
    # Scan for BTLE Wave devices.
    devices = loop.run_until_complete(discover_devices())
    # Get sensor readings from available wave devices.
    for device in devices:
        sensor_readings = loop.run_until_complete(device.get_sensor_values())
        print(sensor_readings)

# >>> DeviceSensors (humidity: 32.5, radon_sta: 116, radon_lta: 113 ...

Testing

You can run the entire test suite by running tox. It will run flake8, isort and pytest. If you'd like to just run unit tests, running pytest ./tests is sufficient.

Special Thanks

I'd like to thank Airthings for their open-source work and commitment to air quality. Radon and other air pollutants often go unnoticed, so knowledge (really) is power here.
