How to reset downgraded sensor channel?

Hi, my channel B went bad a while ago, and I finally got around to replacing the sensors with new ones. It’s all working fine, I see similar data between both A and B sensors. However, on the map it still shows “Laser counter channel B is downgraded. This is usually due to abnormal readings caused by faulty hardware or contamination with debris or insect.”

How do I get the map to know I’ve swapped out sensors and that they’re now both good? I’d like the confidence to move up from the 80% it is currently.

Hi @afx114

The sensor was still downgraded because it was manually downgraded by a PurpleAir staff member. When a laser counter is manually downgraded, it must be manually un-downgraded.

I agree that the sensor looks great and I’ve gone ahead and removed the downgrade. Everything on the map should be looking good.

Please let us know if you need anything else.
