sensor.airthings_wave

hassio support for Airthings Wave and Airthings Wave Plus BLE environmental radon sensors.

Much of the code to build this component was inspired by these projects:

• http://airthings.com/raspberry-pi/
• https://github.com/marcelm/radonwave

The aforementioned radonwave project is especially useful as it describes many of the BLE characteristics specific to this product and has good trouble-shooting tips. The script provided is also very useful in determining the MAC address of your AW device. See here: marcelm/radonwave#3

Getting started

Download

/custom_components/airthings_wave/

into

<config directory>/custom_components/airthings_wave/

Example configuration.yaml:

# Example configuration.yaml entry
sensor:
  - platform: airthings_wave
    scan_interval: 120

Configuration Variables

mac

(string)(Optional) The airthings_wave mac address, if not provided will scan for all airthings devices at startup

scan_interval

(string)(Optional) The interval between polls. Defaults to 300 seconds (5 minutes)

Limitations

It may be possible that the Wave must be connected to the official app at least once before you can use this program, so you will probably not get around registering an account with Airthings.

The radon level history stored on the Wave itself cannot be accessed with this component. To get around this, it connects regularly to the radon detector.

Make sure you install the latest firmware on the device using the official app first.

Known Issues

• Not yet able to specify the monitored_conditions configuration

• No translations available yet

Hardware Requirements

• An Airthings Wave OR Airthings Wave Plus

• A Raspberry Pi 3/4 with built-in Bluetooth OR a Bluetooth adapter that supports Bluetooth Low Energy (BLE). such as this one: https://www.amazon.com/dp/B01N5MGEUS/ref=cm_sw_r_tw_dp_U_x_ObdNCb03P7QZJ
