Connected bulbs are coming to a hardware store near you. But why would you want them? Smartbulbs can be programmed to wake you in the morning, turn on when you’re coming home or change the mood to “romantic dinner” with a click on your phone. They can sync up with other electronics in your home like thermostats or TVs, manage themselves to save electricity and even alert you if there’s a fire. The hard part is keeping things simple.
