I understand your points @kevin1 but the Sense monitor has been going for over 3 years now at least. (As far back as I can look up). And there’s probably no one (outside Sense labs actual controlled environment) that has an absolutely fully functional Sense monitor at home that picks up every device correctly and never gets bad guesses.
To use a similar analogy for comparison, Machine learning can for example recognize items in images by finding patterns, but the less pixelated and less grainy the image is the easier it is to analyze and more accurate it becomes to recognize. Those higher quality images by consequence will take more bandwidth, and computing capacity to process but will yield better results and models.
So I guess the Sense branded plugs I thought of are just the tip of the iceberg. We will need a more powerful Sense monitor to go with it, with much higher bandwidth capacity (someone already wished here for RJ45 connection), and much more processing capacity not just on the local Sense monitor as well as the cloud computing side that Sense Labs probably uses to process all that data. A full new ecosystem probably would propel Sense to the next generation of faster, more accurate “sensing”. Home energy monitoring systems are still in their infancy, especially of this kind, but in the technology world, either one improves and upgrades or gets left behind in the blink of an eye.
