The Lutron Aurora Smart Bulb Dimmer is a wireless, battery-powered local control knob for the Philips Hue smart lighting system. The dimmer easily installs over existing toggle-style switches. The mounting base “locks” the existing switch in the on (up) position, and the round knob dimmer snaps over the base. The Aurora controls like a standard dimming switch, allowing users to touch the dimmer to turn the lights on or off, or turn the knob to brighten or dim the lights. Pricing starts around $40. lutron.com
