"when you are normally away from home to who you interact with regularly."
Didn't we already do this with social media? While my thermostat does sense if I'm not home, it's likely less of an indicator than social accounts where you could find that I might be on vacation. I think the larger issue with a lot of these IOT devices is they just aren't very good, whether it's the interface you use to interact with them or the products themselves, they tend to be serious lacking.
