I had a drip the other day in the pouring down rain and I went up to day and see what was wrong with the vent....that's where the drip was and found this broke off. It has a phone wire running to it and its all corrosioned up. So all I can guess at is a Temperature senor. Or maybe something to do with the awing? Any way it's history.
Thanks for the help!
