I understand and share the concern, but more relevant than the number of devices installed is the actual number of devices identified. After 3 weeks, Sense has identified 15 devices in my home, including a number of the “biggies” including the heat pump, water heater, clothes dryer and fridge. It has not found the electric range (which we do not use much) or the Clipper Creek electric car charger (which they may not have seen before?).
Has Sense not found the significant energy users in your home?
