The new Caséta Smart Motion Sensor links not only with lighting but Lutron's dimmers, fan controls, and Serena smart shades, too. It's a standalone sensor, with a 180-degree field of view.

The Caséta Smart Motion Sensor is a free-standing, battery-powered motion sensor that can wirelessly control Lutron lights and the Serna shades.

Lutron is adding two new accessories to its Caseta line of HomeKit-enabled light bulbs and switches, introducing the Caseta Smart Motion Sensor and the Caseta Repeater.
