- Jesus L.Easy to Set Up and Works Great!I picked up the Ring Alarm Contact Sensor for one of my entry doors and was really impressed with how easy the whole process was. Setup was super simple, basically just pulled it out of the box, followed the app instructions, and it connected without any issues.
What I really liked is that it already had adhesive tape applied, so I didn’t even need to dig out tools or screws. I just peeled the backing off and stuck it directly to the door and frame. Took maybe two minutes total.
It’s been working perfectly since, alerting me right away whenever the door opens. It’s a solid little sensor and blends in nicely without being too noticeable. - Michael TaschWorks greatGreat fixture to add to your home. Easy to install
- Steve H CheungRing Alarm Contact Sensor with SmartThings Hub v2Ring Alarm Contact Sensor works perfectly with SmartThings Hub v2. Very easy to setup.
Add device by scan QR Code, remove small piece of plastic to activate battery, press button for 5 seconds. when you release the button, it flash really quick during pairing with SmartThings Hub. it should show up as Z-Wave device when is done. - Dad BrianWorks perfectlyI bought this as an add-on to my existing Ring security system. These things are extremely easy to install.
I put them on my basement window windows to enhance the security of my house.
It doesn’t make any sound, but it does connect to my existing Ring system. It doesn’t have any motion detection on it either. It just notifies me when my basement windows open or closed. - dineshvery goodease of use very good product
- AaronBuy for added securitySensors are easy to install and integrate seamlessly with the Ring system. Occasionally there’s a slight delay in notifications, but otherwise reliable. Lost one star for the minor lag, but solid security addition
- Glenn TRing Door Sensor InstallationPut these up on deep "box" doors. One a French door and the other a pool door. You can mount the inactive 2nd Gen sensor (smaller component) at a 90 degree angle from the "active" sensor (holding batteries). It works very well with no false alarms. I like all the Ring components we've got around the house, including the new video doorbell we just installed.
