World Air Quality Index

The waqi sensor platform will query World Air Quality Index service to check AQI value for a specific set of locations. The resulting indexes will be added to the Home Assistant as sensor outputs.

To enable this sensor, add the following lines to your configuration.yaml file:

# Example configuration.yaml entry
  - platform: waqi
      - beijing
      - Beijing US Embassy

Configuration variables:

  • locations (Required): a list of location names to look for air quality data. In case a specific location has multiple registered stations all of them will be added to Home Assistant

  • stations (Optional): a list of station names to look for air quality data. Station should be within locations specified above.

The value reported is an overall AQ index for the location. The values of the index can be interpreted as following:

AQI Status Description
0 - 50 Good Air quality is considered satisfactory, and air pollution poses little or no risk
