Yesterday I installed a Shelly 3EM Pro on my main power input. I also have several devices in various zones which are measuring energy. I am not sure how Homey is adding these up.  
My zones are configured as a tree structure with my “home” as a root node. The Shelly 3EM Pro is located on the root node and would represent the consumption of the entire house. I would expect any power measurements on child nodes to be considered a detail of the total measured consumption on the root node.

I am thinking that the energy consumption could be visualized using something like a [Sankey diagram](https://en.wikipedia.org/wiki/Sankey_diagram).

Is this how Homey works or should I convert this post into a feature request?
