With the Philips Hue Bridge Pro, you can connect all your Philips Hue lights in your house to 1 system and make them even smarter. Have 3 or more lights in the same room? Your lighting also works as a motion sensor. The light turns on automatically when you walk into the room. Connect 150 lights and 50 accessories to 1 Bridge Pro and set up to 500 lighting scenes. This allows you to set the right mood in one go, from relaxed to energetic. The bridge works with WiFi or an Ethernet cable, so you can choose where to place it. It also works faster, so you can switch between scenes more quickly and your lighting responds right away.
