If your bed is connected to wifi and your phone has a wifi or cellular signal, yes. You will be able to control your BRYTE BED™ just as if you were in the room.
However, in order to control your Hue lights in the BRYTE App, your phone needs to be on the same wifi network as your lights.
To control your lights while away from home, you can do so in your Hue app if you have set up an account. Visit Philips Hue Support to learn how.
