Smart-home devices like thermostats and fridges may be too smart for comfort – especially in a country with few laws preventing the sale of digital data to third parties

You may have a roommate you have never met. And even worse, they are nosy. They track what you watch on TV, they track when you leave the lights on in the living room, and they even track whenever you use a key fob to enter the house. This is the reality of living in a “smart home”: the house is always watching, always tracking, and sometimes it offers that data up to the highest bidder – or even to police.
