My current solution is to connect the meter (EM24 in my case) directly over modbus and use the riemann sum integration to convert it from kW to kW/h which is the expected unit of the energy dashboard. Pro this will give most accuracy values for import and export but with the drawback you can not monitor the energy going into and out of your battery.
I have played around to see what is necessary to get the data in the shape suitable for energy dashboard. It needs 2 values one for in and one for out. I have not found a nice solution for this with existing HA tools.
That means I need to split the current information of energy flow from / to battery into 2 values and then it will be possible to show battery also in energy dashboard.

Will try to integrate it in next version.
