Customize motion-sensing light controls from your smartphone or tablet. These light controls connect to a free downloadable app using Bluetooth. Use the app to set schedules, control multiple lights remotely, and override the sensor function so you can manually turn lights on or off in the room. Also known as occupancy sensors, they also work without the app—they turn lights on when they detect movement and off when the area is unoccupied. These light controls fit in standard wall plates.

Controls with infrared sensors detect changes in heat sources and require a direct view of people occupying the space to activate.

Controls with infrared/ultrasonic sensors minimize false activation by detecting changes in heat sources and motion. They can be set so that only one or both detection methods are required to activate and hold lights on.

Control the brightness of lights from your smartphone. Using a Bluetooth-connected app on your phone or tablet, you can schedule when lights turn on, adjust their brightness levels, and set their movement sensitivity. Also known as occupancy sensors, these dimmers turn lights on when motion is detected and off when people are away. You can override the motion sensor function with a tap on the app to manually switch or dim lights. They fit in standard wall plates.

Power Controllers—For light controls with DC input voltage, you'll need a power controller to switch a 120V or 277V AC lighting circuit. Power controllers have a relay that switches a maximum 20-amp load.
