I agree this is a "must have’ feature. A device, that you can plug an appliance into, that will help calibrate the sense signatures. I have a large commercial fridge, what you would find in a convenience store, in my basement to store beer. It consumes a lot of power but unfortunately Sense only detects when the compressor goes on. There are fans that are continuously circulating air that consume a significant amount of power, but are reported in the “always on” bucket. Because of this Sense limitation, Sense underreports it’s power consumption by almost a third compared to a Kill-A-Watt that the fridge is plugged in to. A portable module that I could plug the fridge into, for let’s say a period of a week, that talks to Sense would increase the accuracy of the model significantly. Personally, a predicted consumption of a device that is closer to the actual consumption is more important to me as a customer than what Sense actually thinks in measures the consumption to be. To make this even easier, repurpose the Solar Panel ports and I could clamp the ammeter on the circuit that is supplying power to the fridge.
