Consumer-based devices were one of the first segments to adopt things being connected on the internet. Consumer IoT came into form as  a connected coffee pot at a university in the 1990s.  It  flourished with the adoption of Bluetooth for consumer use in the early 2000s. Now millions of homes that have Nest thermostats, Hue lightbulbs,  Alexa assistants, and Roku set-top boxes. People too are connected with Fitbits and other wearable technology.  The consumer market is usually first to adopt these new technologies. We can also think of these as gadgets. All are neatly packaged and wrapped devices that are essentially plug and play.

One of the constraints in the consumer market is the bifurcation of standards. We see, for example, several WPAN protocols have a footing like Bluetooth, Zigbee, and Z-wave (all being non-interoperable). 

This segment also has common traits in the healthcare market, with wearable devices and home health monitors. We keep them separate for this discussion, and healthcare will grow beyond simple connected home health devices (for example, beyond the functionality of a Fitbit).
