Manage consumption in energy tab correctly

Hi and goodmorning,

i would like to ask to community if there is a way to manage my problem.

I have a power meter (shelly em) that measure power consumption to a line, for example line kitchen and return total power consumtion for all equipment connected

Now for some equipment i have a switch (shelly 1PM) to monitor single equipment consumption.

In homey how i shoould configure this situation?

i would like to have in mobile app in energy tab my single equipment listed but i need to add also kitchen line monitored by shelly em because not all equipment are monitored.

so i should subtract single equipment to total kitchen power concumption, is possible?

I was able to explain myself clearly.
