To generate an Airly API key, go to Airly for developers page.
Adding Airly to your Home Assistant instance can be done via the user interface, by using this My button:
If the above My button doesn’t work, you can also perform the following steps manually:
Browse to your Home Assistant instance.
In the sidebar click on Settings.
From the configuration menu select: Devices & Services.
In the bottom right, click on the Add Integration button.
From the list, search and select “Airly”.

Airly allows 100 data updates per day. For this reason, the more Airly instances configured, the less frequent updates will be. For one configured Airly instance, data will be updated every 15 minutes, for two configured instances, data will be updated every 30 minutes, for three configured instances, data will be updated every 45 minutes, etc.
