sensor.airthings_wave

Great news! This HACS component is now deprecated and retired and has been replaced by the official Airthings BLE integration

Please remove this integration and use the official one in its place

A big thank you to everyone who have helped support this integration, and a thank you to @vincegio for porting it into the official Home Assistant repository.

hassio support for Airthings Wave, Airthings Wave Plus, and Airthings Wave Mini BLE environmental sensors.

This component is cloudless and accomplishes this by communicating over bluetooth instead of using Airthings' cloud API.

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
    elevation: 998
    voltage_100: 3.2
    voltage_0: 2.2

Optional 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)

elevation

(float)(Optional) The current elevation in meters. Used to correct the pressure sensor to sea level conditions.

voltage_100

(float)(Optional) The voltage for 100% battery, calculated linearly between voltage_0 and voltage_100 (on supported device), default is 3.2

voltage_0

(float)(Optional) The voltage for 0% battery, calculated linearly between voltage_0 and voltage_100 (on supported device), default is 2.2

Limitations

Users has reported that it is possible to get data without first registering with the official app, so it should be possible to use the sensor with this integration without registering.

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.

It might be beneficial to install the latest firmware on the device using the official app first.

Battery level only works for the Airthings wave pluss device.

Known Issues

• Not yet able to specify the monitored_conditions configuration

• No translations available yet

Hardware Requirements

• An Airthings Wave OR Airthings Wave Plus OR Airthings Wave Mini

• 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
