Contact Sensor (Gen 2) stuck on open

Hi, my contact sensor is stuck on open. It all started with the sensor triggering my alarm while it was armed. I thought my home was being broken into, police were also dispatched. Upon inspection nothing was physically wrong with the window or the sensor and my window was closed. I looked online to see if I could find any solution and followed multiple steps to remove the device, factory reset, and add it back to my base but it continues to say the window is “open”. I even tried replacing the batteries to no avail. Yesterday the sensor kept toggling between open and closed and freaked me out when I heard my base chirping like crazy. For some background info, this particular sensor is located toward the back of my home but I have a range extender. There are also multiple sensors located in the same area that have not given me this problem. The sensor is a little over a year old now. Any help or suggests is much appreciated.

Hi @Jvysun. You’ve covered most of the typical troubleshooting steps I would have suggested for this situation. One more thing I would suggest is taking a different Contact Sensor and putting it on the same window this Sensor is on. If the new Contact Sensor doesn’t exhibit the same issues, then it would be isolated to the original Sensor. If that’s the case, please give our support team a call at one of the numbers available here so they can determine the best resolution.
