Given that companies like Logitech Harmony and SmartThings are themselves hubs for smart devices, this could give the two tech giants a huge supply of new data. Smart remotes will tell them what you watch. Turning the light out will tell them what time you go to bed. Smart locks will tell them whether or not they're engaged. And all of it could tell them whether or not you're at home - if the location data doesn't already.
All of this data combined and analysed (probably by AI) could give a disturbingly accurate picture of your entire life, and coupled with your phone, it won't just be limited to your home.
