Change grid meter measurements

Q&A and troubleshooting

Hi,

here a very advanced question: :slight_smile:

I have a grid meter and several consumption meters, all connected to the gx device. One of these consumption meters should be subtracted from the grid meter’s readings, as if this consumer meter had been connected BEFORE the grid meter.
Is this possible? With NodeRed?
I probably have to write values directly to the VEBus for this?

Or would it be easier to just set the grid set point to the measurement of the consumtion meter that i want to exclude from the ess system?
