For several weeks now my sensor has consistently glowed red but on the map it shows green, as do the surrounding sensors. How to fix this?

Hi Deborah, can you share the Device ID of your sensor?

Please reference this thread ([Sensor glows red but map shows green](https://community.purpleair.com/t/sensor-glows-red-but-map-shows-green/22348)), so we can follow up in both places.
