The energy dashboard’s individual device view is terrific. The utility drops off however, once you add a power monitor for a single high-use device, such as an HVAC system. If a device takes a super majority of a time interval’s time period, it’s very difficult to explore the tiny slivers displayed for the (relatively) lightly used devices.
The traditional visualization approach here is to display values in a log (base 10 or other) scale. This allows all values to be compared regardless of major differences in relative use.
