Emporia has said that they are adding “combining” to the Home screen display and hopefully before 2020 is over. If anybody knows of any details on this, please post or repost!
Regarding @Jcdwing suggestion to show both phases – YES! And this is what I would expect to see – that the multiple phases combined into the Main line would be viewable by doing something like tapping a down arrow on the right of the line and seeing an expanded view of the combined channels.
Energy Use in kW
Main 12.040 100% ^
A 6.140 51%
B 5.900 49%
This same thing would apply to any multi-pole circuit and should be done whether it has sensors on every pole or only one sensor and a “multiplier” as it is currently called (that needs some refinement also) and in such a case, it would look something like this:
Water Heater 4.200 100% ^
A (no sensor) 2.100 50%
B 2.100 50%
Note that the Vue system has detected and is reporting which phase/hot leg it has a sensor on – the same one that is plugged into the current sensor port labeled B and reporting that the other hot leg does have a sensor and the value is mathematically derived.
