What? -1 on my s4nsor mean?
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.
