Hi @No_One_You_Know, where are you seeing the -1?

I am seeing negative one on my purple air map where my house is, why is that. Look on Ballantrae for youself. -1 it says.

I believe this is a current bug with the US EPA conversion factor. If you remove the conversion factor, the readings should return to normal. We will look into this.
