airthings 3.1.1

Fetch sensor measurements from Airthings devices

airthings

airthings is a simple python package that contains methods to communicate with Airthings[1] devices. The package utilizies bluepy[2] for the communication between python and the devices. The package features can be found below.

• [1] https://airthings.com/
• [2] https://github.com/IanHarvey/bluepy

Note: Some features are currently undocumented, and parts are untested/not yet implemented.

Features

• Autodiscover Airthings devices
• Find and search for Airthings devices by using MAC addresses and/or identifiers
• Fetch sensor measurements from various Airthings models, see sensor capability list below

Requirements

bluepy only supports Linux, and is therefore currently the only supported operating system. I have only tested with the Wave Plus Gen 1 (2930). Other device models should in theory work fine, but they are untested or might be unimplemented.

System requirements:

-  libglib2.0-dev

Installation
------------

The current stable version of airthings is available on pypi and can be
installed by running:

``pip install airthings``

Other sources:

-  pypi: http://pypi.python.org/pypi/airthings/
-  github: https://github.com/kotlarz/airthings/

Usage
-----

Examples can be found in the `examples <./examples>`__ directory.

Supported devices
-----------------

*Note: “Model number” are the first 4 digits of the Airthings device
serial number*

Wave Gen 1 (Model number: 2900)

On 1st Gen Wave, temperature and humidity are updated every time we read the wave.

Sensor capabilities ^^^^^^^^^^^^^^^^^^^

• Humidity (%rH)
• Radon short term average (Bp/m3)
• Radon long term average (Bq/m3)
• Temperature (°C)

Wave Mini Gen 1 (Model number: 2920)

Sensor values are updated every 5 minutes.

Sensor capabilities
^^^^^^^^^^^^^^^^^^^

-  Humidity (%rH)
-  Temperature (°C)
-  VOC (ppb)

Wave Plus Gen 1 (Model number: 2930)

Except for the radon measurements, the Wave Plus updates its current sensor values once every 5 minutes. Radon measurements are updated once every hour.

Wave Gen 2 (Model number: 2950)

On 2nd Gen Wave, temperature and humidity are updated every 5 minutes.
On both devices, radon measurements are updated once every hour.
