AirVisual


The airvisual sensor platform queries the AirVisual API for air quality data. Data can be collected via latitude/longitude or by city/state/country. The resulting information creates sensors for the Air Quality Index (AQI), the human-friendly air quality level, and the main pollutant of that area. Sensors that conform to either/both the U.S. and Chinese air quality standards can be created.

This platform requires an AirVisual API key, which can be obtained here. Note that the platform was designed using the “Community” package; the “Startup” and “Enterprise” package keys should continue to function, but actual results may vary (or not work at all).

The “Community” API key is limited to 10,000 calls per month. In order to leave a buffer, the airvisual platform queries the API every 10 minutes by default. Modification of this (via the scan_interval key) to a too-low value may result in your API key being deactivated.

Configuring the Platform via Latitude/Longitude

To enable the platform and gather data via latitude/longitude, add the following lines to your configuration.yaml file:

sensor:
  - platform: airvisual
    api_key: abc123
    monitored_conditions:
      - us
      - cn
    show_on_map: false
    scan_interval: 30
    # Configure by latitude/longitude:
    latitude: 42.81212
    longitude: 108.12422
    # Or configure by location:
    city: Los Angeles
    state: California
    country: USA

Configuration Variables

api_key

(string)(Required)your AirVisual API key

monitored_conditions

(list)(Required)the air quality standard(s) to use (us for U.S., cn for Chinese)

Default value: [“us”, “cn”]

show_on_map

(boolean)(Optional)whether to show a marker on the map at the specified location

Default value: true

scan_interval

(int)(Optional)the rate at which AirVisual should be polled for new data

Default value: 600

latitude

(str)(Optional)the latitude of the location to monitor

Default value: the latitude defined under the homeassistant key in configuration.yaml

longitude

(str)(Optional)the longitude of the location to monitor

Default value: the longitude defined under the homeassistant key in configuration.yaml

city

(str)(Optional)the city to monitor

state

(str)(Optional)the state the city belongs to

country

(str)(Optional)the country the state belongs to

Determining the City/State/Country

To easily determine the proper values for a particular location, use the AirVisual region directory. Once you browse to the particular city you want, take note of the breadcrumb title, which is of the form country > state/region > city. Use this information to fill out configuration.yaml.

For example, Sao Paulo, Brazil shows a breadcrumb title of Brazil > Sao Paulo > Sao Paulo – thus, the proper configuration would look like this:

sensor:
  - platform: airvisual
    api_key: abc123
    monitored_conditions:
      - us
      - cn
    city: sao-paulo
    state: sao-paulo
    country: brazil

Sensor Types

When configured, the platform will create three sensors for each configured air quality standard:

Air Quality Index

Description: This sensor displays a numeric air quality index (AQI), a metric for the overall “health” of the air.

Example Sensor Name: sensor.chinese_air_quality_index

Example Sensor Value: 32

Explanation:

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

Air Pollution Level

Description: This sensor displays the associated Status (from the above table) for the current AQI.

Sample Sensor Name: sensor.us_air_pollution_level

Example Sensor Value: Moderate

Main Pollutant

Description: This sensor displays the pollutant whose value is currently highest.

Sample Sensor Name: sensor.us_main_pollutant

Example Sensor Value: PM2.5

Explanation:

Pollutant Symbol More Info
Particulate (<= 2.5 μm) PM2.5 EPA: Particulate Matter (PM) Pollution
Particulate (<= 10 μm) PM10 EPA: Particulate Matter (PM) Pollution
Ozone O EPA: Ozone Pollution
Sulpher Dioxide SO2 EPA: Sulfur Dioxide (SO2) Pollution
Carbon Monoxide CO EPA: Carbon Monoxide (CO) Pollution in Outdoor Air
