The Light turns on your TV - for some reason
The Sony Multifunctional Light is a fixture which sits on the ceiling of your home and provides illumination. So far, so standard but this device also syncs with your wireless networks to become a smart hub with extra special powers.
For example it has a motion sensor which can trigger when you come into the room to turn on your TV and can also talk to other pieces of tech like your air conditioner. You can even dial into it and use the built in speaker to make kids do things. There's more info on that in this explanatory video.
