It would be great to add a line to the individual devices list to make it add up to the total consumption as displayed in the sources.
This would be the part of the consumption by “unknown” (unmeasured) devices.
It would be even greater to also show the device consumption in a pie-chart (100% = total consumption)
Would love to see the same. Did you already try to calculate it manually? I did (before moving to energy dashboard) and was quite shocked by it. I did this by simply substracting my daily energy sources from the total consumption sensor. With Energy dashboard the calculation becomes a bit more challenging as energy dashboard requires ever increasing sensors so you first need to find the value since midnight and then do the calculations with it.
