You can use AirLink with an existing Davis system that is uploading to the WeatherLink Cloud. Your air quality will appear on your WeatherLink.com bulletin page as well as on your WeatherLink app. (It will not appear on your Vantage Pro2 or Vantage Vue console.)
At the time you set up your Airlink (using the weatherlink app) you will have a chance to specify the weather station it is too be associated with.
