After 4 months of using Sense I’m still at 71% “Unknown” and 10.5% “Always On”. The big items in the Unknown are - (1) an electric car, (2) a hot water heater, (3) oven, (4) clothes dryer, I have no idea what’s in the “always on”.
Sense is useful to give me a big picture view of energy usage and on many fronts is a very well designed product. The App is brilliant, and the hardware works as well as any IOT device I’ve used. But that isn’t what the company promises. The promise is to drill deeper into a home’s energy usage and that’s where the product fails. The tech behind device detection makes good press but it simply does not work (at least in my case).
