core: AirNow Integration has error "No results found for that location"

The problem

AirNow has been giving me trouble for a little while. I removed it and am trying to re-add it.

The lat/lon fields are filled with numbers that are very very long. I’m not sure if those came from my HA location or what. There are 14 digits past the decimal place.

When I type those large numbers into the AirNow web query the boxes turn red, and the URL is built funky, so it doesn’t work.

When I type smaller numbers with only 4 decimal places into the HA add integration box, I get a “No results found for that location, try changing the location or station radius”. The Latitude/Longitude fields reset to the long numbers and my API key is removed.

When I use smaller numbers in the AirNow query website, I get this response:

"DateIssue","DateForecast","ReportingArea","StateCode","Latitude","Longitude","ParameterName","AQI","CategoryNumber","CategoryName","ActionDay","Discussion"

Maybe that is the core issue? The state of CO doesn’t have any useful data right now?
