VRM data solar-to-direct-use not correct

Hello,
In a new installation I have an issue with the data shown on the VRM.
The setup is a multiplus II GX 5000VA (L1 to AC-IN) with an ET340 (grid meter) and ET112 (PV on L1) on the same RS485 bus with changed modbus ID’s.
AC-OUT is not used.

The realtime data seems correct:

The battery is trying to keep the grid-setpoint at 10W.
During the day, the solar energy is supplying the house and/or charging the battery.

Yet I get this graph for solar production.

It’s strange to me that solar-to-direct-use is almost zero while I would expect a graph like this. (same day from another installation)

Here it’s clear that no energy is wasted.

Also, the consumption graph shows a lot of consumption from grid while in reality most of the consumption was supplied by solar power or battery.

To me it seems like a visualisation issue in the VRM.

Does anybody have any idea how to solve this?

Thanks

Hi All,
I have similar issues with the just installed Energy Meter VM-3P75CT. The MP2 is only delivering 1 Phase on AC Loads but VRM showing 3 Phases. Energy Meter is configured as Grid meter.

I think I have solved my issue.

Do you have a 3-phase Multiplus setup?

No.

The graphs seem to be quite broken, my installation shows no direct use at all (though no MP2 there, just normal inverters):
