    Does not work with SmartThings despite people saying that it works for them - from two sensors I bought, one paired properly but showed as smoke and leak sensor besides a contact sensor and the other one doesn't pair at all. Would have uploaded pictures if this defective site would've let me.

      Hi Twintips007.

      Thank you for taking the time to share your experience with us. We understand the importance of having your Ring Alarm Contact Sensor 2nd Gen to operae as intended so that you can effectively monitor your home. The features and technology behond the Ring Alarm Contact Sensor 2nd Gen are incredibly valuable and help provide you with peace of mind about your home security. We can definitley provide you with more information regarding the concern that you mentioned in your review.

      It sounds like you are experiencing an issue with reinstalling Ring Alarm Contact Sensor. The best way to remove a Contact Sensor would be to use a hairdryer to soften the adhesive and then using a putty knife to peel the Contact Sensor off of its mounting surface without damaging that area. 3M double sided tape or 3M Command Strips is also a great replacement for the adhesive and can be found at most stores or online.
