Door Sensor no detecting door open/closed

Question

A couple of days ago the door sensor stopped chirping when the door was opened, checked the app it's still connected ok, did a reset but it's still the same, but it would appear that it isn't detecting the magnet as the door is opened/closed.  I've tried it on a couple of different doors too and it didn't work.

Hi @DaveDC! As long as the magnet for the Contact Sensor is within 1/2 inch from the proper side of the Sensor as show in this [help center article](https://support.ring.com/hc/en-us/articles/360039497552-Ring-Alarm-Contact-Sensor-Setup-and-Use), this should work consistently. As it sounds like this was working prior to recently, please also check the battery in the Ring app. Feel free to send an image example of the mounting for further suggestions. :)
