Since all loads go through the Multiplus, I'd expect measurements to be close to what my "official" meter gives me, however the values are very much off.
Today, VRM shows me 6.5 kWh imported from the grid, while the meter shows 0.1 kWh only. When it comes to power sent into the grid, the values are very close (59 vs 61 kWh). Grid metering is configured to "Inverter/Charger", there is no other additional meter installed. Is there any way this can have been misconfigured on my end?
