Map button reads low, time graph appears correct. [image] I blew compressed air through the unit displacing some dust, but map appearance has not changed. Any thoughts? What is the recourse if unit has become defective?

Channel B downgraded

Time graph for unit above, showing more correct PM value, and July 4 fireworks spike.

My sensor isn't updating on map, but data works when you click in
