Hi,
I have a device powered by the 48V DC power. I have the current power consumption already available in NodeRed on the Cerbo. Is there a possibility to feed in this consumption as a consumer device for the DC power?

Moved to modifications space as it's a Node-red question.
Hi @plot
You could use a custom driver setup to behave like a virtual smart shunt. Then either pass the data from node red to the "virtual" smart shunt via MQTT. Or pass it directly via dbus using exec nodes.
Here's how to do it:

Here's an example dummy script:
velib_python/dbusdummyservice.py at master · victronenergy/velib_python · GitHub
In the dummy script you'd need to change com.victronenergy.dummyservice.ttyO1
to I think it'll be something like:
com.victronenergy.dcsource.ttyO1
or
com.victronenergy.dcload.ttyO1
but here's dbus info just in case im wrong you can find the right one.
