The light is off. War is over
TL;DR: he stayed over at a friend's place in a densely packed condo unit. Condo building has a home automation system with binary codes that has a limit of 16 combinations. With 40 units nearby, each unit controls at least 1 other automation system in a neighbor's apt, so one of his neighbors was accidentally toggling his light.<p>Even better are the replies from other Twitter users on the same thread on what they experienced with their home automation systems. Here's one that tickled me: "We had an Airbnb guest once who (probably accidentally) connected his Spotify Connect to my living room sound system. Months after he was gone, death metal would start without a warning, volume went up, silence after 5 seconds. It took weeks before I figured it out"<p>It's crazy how sometimes these automation systems that are supposed to make our lives easier, make it more complicated instead. I wonder when the issues that we see today with smart houses and smart TVs will show up in the upcoming generation of "smart" cars.
