Fronius Bindung with 2nd inverter and one Smart Meter

I have added a small solar plant to my existing solar plant. Existing solar plant is with Fronius inverter.
The inverter of the small plant is connected to the Fronius Smart Meter.
On the web interface of the Fronius inverter I see the cumulated current power of both plants. (see attachment)
In the Fronius binding I only see the current power of the Fronius inverter. Is there a change that I receive this cumulated power value via the fronius binding?
I have also checked the fronius API and it seems that there is no cumulated value available.
As an option I can sum up both values in OH per rule.
