Door sensor alternates between open and closed after door is opened

One of my door sensors has started acting weird. After I open the door it will start alternating between open and closed even though the door is fully open and the two parts of the sensor are no where near each other. It’s been set up for over a year and working fine and nothing has changed. If I leave the door open it will eventually stop going off but it usually takes 4-5 mins.

Hi @user26939. Try the troubleshooting steps outlined here if you have a 1st generation Contact Sensor or here if you have a 2nd generation Contact Sensor. Factory resetting the Contact Sensor and adding it back through the Ring app should help resolve and performance problems like what you’re experiencing. If this persists, please give our support team a call at one of the numbers available here so they can take a closer look with you.
