This sensor in Barcelona shows the temperature as 97 degrees F (36 C) which cannot be correct.
Not sure how the community can help but they said to post this here.
Five days later, still wrong, showing 89F. Other sensors show more reasonable temperatures in the 60s.
OK, an adjustment of -8 degrees is not enough. It would still show 81 degrees on a day when it was 64. The sensor itself isn’t registering correctly. The sensor might need to be replaced.
It isn’t my sensor so nothing I can do but report the issue. I was hoping that PurpleAir would do something.
