Airthings

This extension adds support for Airthings (opens new window) indoor air quality monitor sensors.

Supported Things

Following thing types are supported by this extension:

Thing Type ID	Description
airthings_wave_plus	Airthings Wave Plus
airthings_wave_mini	Airthings Wave Mini
airthings_wave_gen1	Airthings Wave 1st Gen (SN 2900xxxxxx)

Discovery

As any other Bluetooth device, Airthings devices are discovered automatically by the corresponding bridge.

Thing Configuration

Supported configuration parameters for the things:

Property	Type	Default	Required	Description
address	String		Yes	Bluetooth address of the device (in format "XX:XX:XX:XX:XX:XX")
refreshInterval	Integer	300	No	How often a refresh shall occur in seconds

Channels

Following channels are supported for Airthings Wave Mini thing:

Channel ID	Item Type	Description
temperature	Number:Temperature	The measured temperature
humidity	Number:Dimensionless	The measured humidity
tvoc	Number:Dimensionless	The measured TVOC level

The Airthings Wave Plus thing has additionally the following channels:

Channel ID	Item Type	Description
pressure	Number:Pressure	The measured air pressure
co2	Number:Dimensionless	The measured CO2 level
radon_st_avg	Number:RadiationSpecificActivity	The measured radon short term average level
radon_lt_avg	Number:RadiationSpecificActivity	The measured radon long term average level

The Airthings Wave Gen 1 thing has the following channels:

Channel ID	Item Type	Description
radon_st_avg	Number:RadiationSpecificActivity	The measured radon short term average level
radon_lt_avg	Number:RadiationSpecificActivity	The measured radon long term average level
temperature	Number:Temperature	The measured temperature
humidity	Number:Dimensionless	The measured humidity

Note: For the Airthings Wave Gen 1, only one channel can be updated at each refreshInterval, so it will take refreshInterval x 4 cycles to sequentially update all 4 channels

Example

airthings.things (assuming you have a Bluetooth bridge with the ID bluetooth:bluegiga:adapter1:

bluetooth:airthings_wave_plus:adapter1:sensor1  "Airthings Wave Plus Sensor 1" (bluetooth:bluegiga:adapter1) [ address="12:34:56:78:9A:BC", refreshInterval=300 ]

airthings.items:
