Noticed my sensors were not measuring correctly, confidence was at 5%. Took the sensors down and cleaned them using the videos posted. The sensors are reporting 95%-100% confidence but still off compared to the other sensors in my area. Short of buying replacement sensors, is there anything else I can try. I cleaned them a few days ago.
I had same issue - popped them out, pulled off can covers carefully and cleaned out carefully with earbuds. One of them had a whole spiders nest in..
