Air Quality Binding

This binding uses the service for providing air quality information for any location worldwide.

The World Air Quality Index project is a social enterprise project started in 2007. Its mission is to promote Air Pollution awareness and provide a unified Air Quality information for the whole world.

The project is proving a transparent Air Quality information for more than 70 countries, covering more than 9000 stations in 600 major cities, via those two websites: and

To use this binding, you first need to register and get your API token.

Supported Things

There is exactly one supported thing type, which represents the air quality information for an observation location. It has the aqi id. Of course, you can add multiple Things, e.g. for measuring AQI for different locations.


There is no discovery implemented. You have to create your things manually.

Binding Configuration

The binding has no configuration options, all configuration is done at Thing level.

Thing Configuration

The thing has a few configuration parameters:

Parameter Description
apikey Data-platform token to access the service. Mandatory.
location Geo coordinates to be considered by the service.
stationId Unique ID of the measuring station.
refresh Refresh interval in minutes. Optional, the default value is 60 minutes.

For the location parameter, the following syntax is allowed (comma separated latitude and longitude):


If you always want to receive data from specific station and you know its unique ID, you can enter it instead of the coordinates.


The AirQuality information that is retrieved is available as these channels:

Channel ID Item Type Description
aqiLevel Number Air Quality Index
aqiDescription String AQI Description
locationName String Nearest measuring station location
stationId Number Measuring station ID
stationLocation Location Latitude/longitude of measuring station
pm25 Number Fine particles pollution level (PM2.5)
pm10 Number Coarse dust particles pollution level (PM10)
o3 Number Ozone level (O3)
no2 Number Nitrogen Dioxide level (NO2)
co Number Carbon monoxide level (CO)
observationTime DateTime Observation date and time
temperature Number Temperature in Celsius degrees
pressure Number Pressure level
humidity Number Humidity level

AQI Description item provides a human-readable output that can be interpreted e.g. by MAP transformation.

Note that channels like pm25, pm10, o3, no2, co can sometimes return UNDEF value due to the fact that some stations don’t provide measurements for them.

Full Example

UNDEF=No data
NULL=No data
NO_DATA=No data
UNHEALTHY_FOR_SENSITIVE=Unhealthy for sensitive groups
VERY_UNHEALTHY=Very unhealthy
