VRM consumption-history faulty!?

Hello!

This morning the battery was full and in ESS i set the Grid-Setpoint to 10W, so about 10W should be always come from the grid - when i look to the VRM-dashboard the watts for grid-consumption are about 10W in average -> everything ok.

- From 7-8am everything comes from the battery
- From 9-10am nearly everything comes from the photovoltaic

But when i look into the VRM consumption-history:
- From 7-8am consumption 0,95kWh -- 0,73 vom battery and 0,22 from grid
- From 9-10am consumption 0,93kWh -- 0,57 vom PV, 0,07 from batt. and 0,29 from grid


Why is the consumption from grid so high?
10W for one hour should be 0,01kWh and not 0,29!?

Is there an error in the system or is it normal and i only have to turn down the grid-setpoint?
(I don´t have any extra energy-meter or something:
Cerbo-GX, 3x Multiplus 2 (VE-Can), 2 MPPT (VE-Direct), complete house on output 1)

Now i noticed from 11-12am with excessiv PV-production the grid-consumption went down to 0,04kWh which seems ok.

Is the regulation to slow with less PV-production?
