Confidence Level

I have two PurpleAir Flex sensors placed side by side.

One is giving me 100% confidence score while the other is giving only 49% confidence score. I have reset the networks and restarted everything and even changed the location where I am testing them. I suspect that one of them is faulty.

Hi @arsvelasco

A 49% confidence score does indicate that some sort of issue is occurring. This could be something as simple as debris inside the device. Generally, sensor maintenance is a good place to start. Additionally, what is the name of your sensor?
