Welcome @ta4 - I moved your question to its own topic. The quick and dirty answer is that the percentage of detected usage varies widely depending on four things:
- The types of devices that use most of the energy in your house
- The amount of noise in your house from various devices - noisy devices can hide others from Sense
- How much you make use of integrations (smart plugs, DCM, Hue, Ecobee historic, Wiser) to fill in the blanks.
- How much you are willing to do to itemize the devices contributing to Always On.
I’m on the lucky side - low house noise and many of my big ticket items are easily detectable. He’s a snapshot for Feb - Other is only 7.2% with Always On at 18.3%. I have one and 1/2 days missing due to a power/internet outage. There are 3 smart devices contributing to 9.7% of the top device detection (Furnace Down, Kitchen Overheads, and Switch), but the biggest loads are native detections.
And when I look down into my Always On, I have 151W of 462W accounted for - that’s without any exhaustive itemization.
