    I purchased these to add to Smartthings, it takes a little extra work and the Smartthings IDE but they are working flawlessly. Nice to have a bit of extra protection knowing when certain doors are opened.

    Ring is as good as any smart home security alarm out there. Easy to install and it comes with tools and accessories you needed to install it. It’s better if you have smart phone for easy install and programming.

    After having the Ring security system set up im my house, I realized that I didn't cover one of my doors. I ordered this sensor from Best Buy and decided to do it myself. The install was very simple. I got it early and I was pleased.

    So far all 15 sensors are working great. I forgot that we placed one in a new location where I never had one with ADT. When I opened the door I hadn't turned the alarm off and suddenly I see Ring Alarm on my phone. So they are working.
