how can i emulate a bmv700 with input from a votronic smartshunt

Hi

i have a raspi 4 with the large Venus OS image on it and a connected mppt100/30 .

output is a 7inch ips touch panel. This works very well.

Node red is activated and i use this to decode the serial output from a vortronic 400A Shunt so i have now following values in node-red at the moment:

- Voltage from the Board and Starter battery in V

- strength of the electrical current in A

-Battery level of the board battery in %

-size of the Boardbattery in AH

now i would like to send this as input to emulate a bmv7xx to the venus os to show it on the display as a bmv.

has someone a idea , best of would be directly in node-red itself

thanks in advance
