Sync your hue lights to the content on your TV to create an immersive entertainment experience. It works with every TV. Connect the source to the sync box, connect the sync box to the TV, and you're ready to go. The sync box can be controlled using your existing remote controller to avoid introducing another physical controller to the house, but it can also be controlled through the Hue Sync app. The product has only one button; on/off, with an integrated red window for the remote control signal. The bottom of the product is made of soft rubber to avoid scratches on often high-gloss or super-matt TV cabinets.
