I have a energy monitor system in the breaker box (Emporia VUE), and I want to resolve the consumption on one VUE monitored branch using smart plugs with sensors for individual devices connected to the branch. How do I get the display right, I want to show devices and the the remaining energy of the branch (VUE branch - device 0 -device1). How can this be achieved? Is it possible to indicate that a devices measurement is hierarchically under a different one, or are there methods to create a virtual device that represents the difference above?
For the second solution option, the manual subtraction, I believe I will need to learn building virtual devices with templates…
