The consumer sector is a great way to make money. People love buying stupid gadgets. And people already schedule purchases on Amazon every month - the sensor method is just an extension of this to save money/prevent waste. Eventually, if any company actually tries to do it right, sensor-driven consumer goods will become the norm. There's too many actually productive uses for sensors in the home for it not to be pursued.

The other reason you only see this stuff in the consumer sector is that non-consumer use of IoT is a hot garbage fire. Mesh networks used for industrial sensor tracking at scale are shit, no matter what high or low level protocols you use, and nobody has developed standards ubiquitous and unencumbered enough for everyone to adopt. And everyone already has connectivity for the devices and sensors that need them.
