It’s actually quite simple. Existing connected products, from those in the home to in our car, don’t communicate with each other very well. To make our homes (and lives) smart, they all need to talk and interact with each other, seamlessly.
Here’s how smart home work. At the moment, a connected thermostat learns your regular movements, so it makes sure the house is warm when you get home at six. But it’ll probably be freezing if you come home unexpectedly at 4. The smart home would have had a good conversation with your car to know you were headed home early, and that it’s because you’re not feeling well, then adjust everything accordingly — if you had a fever, you wouldn’t want a baking house. To get the same result in the connected home, actions are required on your part and forget about any of it working if someone else is already home and has changed the settings already.
