Is this compatible with other brands’ lights also?

Hello, Great question! No, the Ring Outdoor Motion Sensor is not compatible with other brand name lights. The stand-alone Ring Motion Sensor (requires Ring Bridge or Echo device used in place of a Ring Bridge) lets you monitor for motion in areas where you don’t need a light, doorbell, or camera and is battery-powered for easy no-wiring installation.
