A:Answer You set the lights up into “rooms” and can control the entire room as a whole, or just the specific light. For example, in my kitchen, we have a built in area that we have these lights in a lamp, then we have other hue lights throughout the kitchen, as well as light strips. If we want to dim the entire kitchen, we can, or by tapping on the room that we named “Kitchen”, you will see each individual bulb and can dim or turn of bulbs individually. If you have the color bulbs, it works the same. You can change the color of an entire room, or just individual bulbs.
