Yesterday I bought a Sense HAT that seemed to be defective. I had the unit inside and it seemed to be displaying lower than it should, so I put it outside to compare against what the weather was reporting and I found that it was off - displaying -40%. I did some searching and found that this was a problem for many people back in 2016 - apparently there was a defect but it was corrected. I returned the Sense HAT to the store to get a new one but found the same problem. Humidity outside was 25% and the Sense HAT was displaying -21%.
Is anybody else having issues with these again? Is this a common problem? I don't want to keep returning them to the store just to get home and find that the next one is defective as well.
