Find QR code

I do not have a QR code for my sensor. It had a critical error and I read somewhere that you needed to remove it, reset it by removing the batteries and the you could add it back. When I try to do this the Ring didn’t find another device so I was trying to add it manually but you need the QR code (5 digit number). I do not have the QR code because you put that on the package, not the device. Can I get the QR code or 5 digit number from the DSN.

Hi @abell118. The QR code for your Contact Sensor or Motion Detector should also be located on the inside of the cover that is removed to replace the battery. You can find more setup information for the Contact Sensor in our Help Center Article here, which will have information on both the 1st and 2nd generations.
