I have an all-electric house that is about 3500 square feet, on 3 levels. I have a water source heat pump, 2 water heaters, 2 refrigerators, 2 freezers, and an electric car. Great place for a Sense!
I knew going in that I was using about 3000 kWh per month.
For some reason, my fan blower motor draws 1.5kW. I was running that full time, and changed it to only run when heating or cooling. That saves about 750 kWh per month! I need to find out from the HVAC guys why that motor draws so much power.
I also found that my Always On is 600W. I knew I had some garage lights and computers on, but hadn't calculated the amount. I now have that down to 260W. That savings is enough to cover the electric car driving to work. It is amazing how quickly the always on devices add up.
After seeing the energy usage of my lights, and with a big sale on LED bulbs, I have now upgraded most of my bulbs.
I also know now that my old refrigerator (25 years) uses twice the energy of the newer refrigerator, but I'm not planning to replace it yet.
I still have a number of big devices that need to be detected, but I look forward to studying the seasonal trends of each device like heating, dryer, which well pump, etc.
