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
sensor:
  - platform: waqi
    locations:
      - beijin

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

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
51 - 100	Moderate	Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution
101 - 150	Unhealthy for Sensitive Groups	Members of sensitive groups may experience health effects. The general public is not likely to be affected
151 - 200	Unhealthy	Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects
201 - 300	Very unhealthy	Health warnings of emergency conditions. The entire population is more likely to be affected
301+	Hazardous	Health alert: everyone may experience more serious health effects
