At the heart of your Philips Hue system, the Bridge works with HomeKit for Apple iPhone integration, allowing you to connect up to 50 lights for enhanced customizable lighting. You can control your lights with Siri voice control and turn your existing Hue lights into HomeKit controllable lights. With the bridge, you can expand your Hue ecosystem and control your lights remotely or link them up to the rest of the web, news feeds, or even your inbox.
