How to program aux relais on Cerbo GX or Multiplus2 depending on Grid feed

Hello community,

I'm using a ESS with Cerbo GX, Multiplus2 and EM24 Energy Meter. I want to use the relais Output on the Multiplus 2 or Cerbo GX to trigger an external device when the grid feed out exceeds e.g. 2000Watt and stop it when it goes below e.g. 1500Watt. Can someone explain how to do this? I just had a look in the assistants, but found no way to use the feed in/out power from the EM24 as a signal.

Thank you for your help.

Does no one know how to setup? I found this post:

https://community.victronenergy.com/questions/155009/relais-on-cerbo-to-control-consumers-under-ess.html

Basically stating that this should work. But I found no assistant that enables to use the Grid feed in/out power as a condition.

One more thing I found out: My multiplus is connected in parallel to the main grid, so ACOut1/2 are not used. When connecting the Multiplus in series to the grid, I think I could use the ACInput as signal. But in my case ACIn does not reflect the same value as the measured values from EM24.


Thanks for any hints

regards

Michael
