We joke about the internet of things with all of these wifi devices. With my nest thermostat, I can control Temps without having to get out of bed or can be out of town and shut off the AC, or it can use my location to do that for me. As soon as I'm close by I can start up the AC and make it comfy. Over time we will get used to these features and we won't be able to live without them.
I also have water detectors that can detect leaks and notify me before a disaster happens.
