Create additional sensors for power flow

[Fayrewood]

For power sensors picked up from the EMS via GE_Cloud (GE API), I only see the following sensors, which don't allow me to map out the actual energy flow:

• Battery Power
• Solar Power
• Consumption Power
• Inverter Power

Somehow, the Energy Dashboard shows the total energy sensors attributed to the house, battery and solar, but I can't find individual power sensors for the same.

It may be a limitation on what is available in the GE API, but is is possible to create additional power sensors to show the flow of energy?

e.g:
Solar -> Grid (Exporting)
Solar -> House Load (Demand)
Solar -> Battery (Charging)

Battery -> Grid (Exporting)
Battery -> House Load

Grid -> House
Grid -> Battery
