Oh, Boy; do we feel STUPID and embarrassed.
This morning my husband woke up with an idea. He looked up under the eaves, about a foot upward from the closet where the Fios box is - and found something.
He had an old weather-watching set, with a monitor that communicates with a component inside to tell us temp, humidity, etc.
It quit working years ago, and we forgot it was there. Today, he found it and took it down - and that’s what was making the noise. It sounds exactly like the Fios box when it needs a new battery - except that it goes off every 3 minutes.
Husband said I shouldn’t tell you all this, because he’ll look like an idiot. But we didn’t even know that thing was still up there.
Peace and quiet for hours now! And we appreciate the time and effort everyone took to try and help us.
(We’ll slink off somewhere now, and succor our collective ego. But in a few hours, I may ask you if it’s ‘legal’ to call the cops on people throwing off fireworks all night...beginning a week before the 4th.)
Thanks again.
Love it. He found it, not an idiot. I cant tell you how many beeping smoke alarms I got wrong first. lol, thanks for sharing the result. I wondered.
