  4. Sengled - Smart Window & Door Sensor (2-Pack) - White - Front_Zoom
    Top comment

    "Purchased these contact sensors to use in my smart home setup. Works well with my Sengled bulbs and Smartthings hub....Best price smart sensor windows...I use to have some Chinese knock off brand ones that required device handlers but these are so much better. They support most smart hubs natively out of the box. With Samsung Smart things it took a couple minutes to setup and connect. "
