This is a Home Assistant Lovelace card that uses the AirVisual Sensor to provide air quality index (AQI) data and creates a card like the ones found on AirVisual website. Requires the AirVisual Sensor to be setup. Tested with Yahoo and Darksky Weather component.

• Card colors and icons change depending on AQI level

1. Open the HACS on your Home Assistant instance.
2. Open the Plugins section and click on the Air Visual Card.
3. Click on Install, then click on "Add to Lovelace"

1. Download the AirVisual Card
2. Place the file in your config/www folder
3. Include the card code in the Resources section of your ui-lovelace-card.yaml like below:

resources:
  - url: /local/air-visual-card.js
    type: js

4. Optional: If you wish to store the Airvisual icons locally, then download the icons here.

5. Save the icons in a directory in Home Assistant, such as ''/local/icons/aqi_icons"

6. Update the card configuration in ui-lovelace.yaml to include the following (use directory name in step #7):

    icons: "/local/icons/aqi_icons"

1. Install the AirVisual sensor and confirm AQI, APL, and Main Pollutant sensors are created, like below.

2. Write configuration for the card and list your AirVisual sensors. MAKE SUREAn examples is provided below:

Direct editing within the YAML files (ui-lovelace.yaml)

  - type: 'custom:air-visual-card'
    air_pollution_level: sensor.use_the_actual_name_of_your_sensor_not_this_example
    air_quality_index: sensor.use_the_actual_name_of_your_sensor_not_this_example
    main_pollutant: sensor.use_the_actual_name_of_your_sensor_not_this_example
    temp: weather.use_the_actual_name_of_your_weather_entity_not_this_example
    city: 'San Francisco'

Adding via the Lovelace UI Card Configuration

type: 'custom:air-visual-card'
air_pollution_level: sensor.use_the_actual_name_of_your_sensor_not_this_example
air_quality_index: sensor.use_the_actual_name_of_your_sensor_not_this_example
city: Moscow
main_pollutant: sensor.use_the_actual_name_of_your_sensor_not_this_example
temp: weather.use_the_actual_name_of_your_weather_entity_not_this_example

3. Refresh Lovelace to load the card.

• The card doesn't show the temperature properly.

  Let me know which weather provider you are using and I'll try to fix the issue. I have only tested with the Yahoo! Weather component. Optionally, if you create a template sensor that reports the temperature as its state, you can use that sensor as for the temp config.

• This card doesn't work in Fully Kiosk Browser on Amazon Fire tablets. Why?

  This card uses a new CSS function, CSS Grid Layout, which was implemented in October 2018, and isn't compatible with browsers using old versions of Android WebView. That's my guess anyways.

• The card is showing the word 'unavailable' instead of the AQI data!

  Most likely your Airvisual key expired (it has a one-year expiration) and needs to be recreated. Delete and recreate a new key on airvisual.com and save the key in your HA config file.

I am studying programming as a hobby and this is my first set of Home Assistant projects. Unfortunately, I know nothing about Javascript and relied on studying other Lovelace custom cards to write this. Suggestions are welcome but no promises if I can fix anything! If you're familiar with CSS, then you can edit the CSS style in the .js file directly.
