>it is not supposed to start chirping unless it is out of range of your phone for at least 8 days, and not in one of the predefined geofence regions you can setup where it won't chirp.
Does it even chirp then? This is news to me, I have an airtag in my car and have certainly left it for 2 weeks during vacations. I've never heard the airtag chirp unless I make it play a sound through "Find My"
Your home is usually automatically geofenced, so if you left it there it shouldn't chirp. If you parked your car elsewhere, e.g. an airport lot it was probably chirping while you were gone, but you wouldn't hear it because you weren't there.
They only chirp when disturbed (when separated from their paired device). I've got an iPad paired to a set on my keys, no iPhone. If I let the iPad die, eventually the airtag will start chirping when I pick up my keys, but when I'm not touching them they don't chirp.
