Ring contact sensor works only one magnet is touching the sensor

I have the Ring alarm setup and all of a sudden one of the contact sensors stopped working. I changed the battery and it will still not work. Other sensors worked with the same battery. Then I removed the senor and magnet from the door and it would work (show “Open” or “close”) when the magnet is in contact with the senor.

It should work when the magnet and sensor are up to one inch apart but mine won’t work until I bring them really close to each other.

Is this sensor defective? Any tips and tricks to resolve this issue?

Thank you in advance.

Hi @RJ2207. This could be because of a a few different things. First, what is the surface the Contact Sensor is mounted on? If it is metal or brick for example, it could be experiencing interference. Secondly, what is the distance from the Contact Sensor to the Base Station? If it is too far, you may need to add a Range Extender halfway between the two.

Hello Tom,

Thank you for your response. The sensor is on a wooden surface. And it is right next to the base station. In fact, it was working fine for many months and then all of a sudden it went offline. I changed batteries and teried again and it wornt work. But if i remove the sensor and the magnet and keep them very close (less than 2-3mm), it responds. Any more distance and it won’t respond.

I am guessing ts a faulty sensor.

Thank you,

Hi @RJ2207. The Contact Sensor should perform well on a wood surface. I suggest resetting your contact sensor and adding it back to your system. This Help Center article here has information on how to do this. If you are still having issues after that, you may need to reach out to our support team. Please give our support team a call at one of the numbers available here. If you are outside of the US, please visit here to see how to contact support.

I was trying this out and got some issues and still finding it can you give some more suggestions if any thanks in advance.

Hi @Isac. As suggested above, a picture of how your Contact Sensor is mounted is a great start.

If it’s mounted on wood, is it painted? There very well could be a nail behind which could be interfering.

Have you tried taking both out and testing them to verify if the location is not causing the interference?
