My issue is there still after swap, beginning to think its defective or the wiring in the house is not wired properly as I tried to get a reading of the transformer and the multimeter is not showing the right numbersCurrently I have the one that came with the house which is a NuTone 515-t and its' a 10v 5w transformer. So it might be that it's not giving enough power to the unit.
I have just purchased a brand new chime a couple months ago so it should handle higher voltages.
I can also confirm that I flashed the firmware with the original EZVIZ and it still was offline this morning. Will upgrade the transformer and check to see if it keeps happening.
