Aeotec Home Energy Meter 2nd Edition

[Gertschi]

Hello,
there is an issue with my HEM.
The value Powerconsumtion on ID 240 should be an algebraic sum and not the sum of absolute power of L1, L2 and L3. Because my inverter produces elektricity.

The issue is, that L1, L2 and L3 shows also negative values, thats when my inverter generates more power then I consumes.
But the device for the whole powerconsumtion on ID 240 shows only the sum of absolute Power [W]. The energy meter [kWh] on ID 240 shows the correct values.

Is there a way to show the algebraic sum for the whole powerconsumtion, without writing a script witch writes the values to a new device?
