Clarification of positive/negative value meaning for currentPower feature #1
Description
When experimenting with the API, I found it quite hard and confusing to figure out whether currentPower values should be positive or negative for the following device types:
- INVERTER
- BATTERY
- GRID_CONNECTION_POINT
It's also hard to figure out the correct configuration because the HmIP app's energy dashboard is also quite confusing and does not visually show the flow of power between the components such as Home Assist's power flow card plus does (https://github.com/flixlix/power-flow-card-plus).
Would be nice to have a clarification in the docs about the meaning of positive/negative values for devices that support bi-directional power flow.
