SMA Tripower // Modbus // Total consumption or Grid feed-in

Hi,
I run a SMA Tripower STP10.0-3SE-40 865 inverter and have it connected via modbus.
I would like to set up a logic which toggles a switch whenever I produce e.g. 3000W more than I use.
I have already managed to get the currently produced power (Register 30775) but I do not know where to find the total consumption or the grid feed.
Would be great if you could help me out!

See my yaml details below

Thanks,
