Hi All,
currently AirVisual component can be configured only by latitude and longitude inputs
AirVisual Documentation
According to AirVisual it is much better and more effective to find nearest sensor by state/region/city input: I had experience of current HASS integration to pick up the wrong city.
Syntax is:
http://api.airvisual.com/v2/city?country=YOURCOUNTRYNAME&state=YOURSTATENAME&city=YOURCITYNAME&key=INSERTYOURKEY
