HASS + NODE RED controling VICTRON EVCS

In the Cerbo GX, the OS-Large Node Red option works and can be activated (for now deactivated)

1 - HACS downloaded the Victron GX modbus TCP

2 - Installed Node-Red Add-on in HASS

3 - Installed the Integration Node-RED Companion

3 - In HASS imported in Node Red the victronenergy/node-red-contrib-victron.

As result: All Victron labels are showing in the HASS - Node Red library, but cannot function.

Questions: i need help on this idea

The MQTT integration for Victron in HASS works okay with the standard (limmited )automations and reading of values.

I want the HASS add-on Node Red programming availlable to control the Victron Cerbo-GX and Victron EVCS based on various HASS controls like Energy lowest day-price.

Is this all possible or a utopie?

thanks for your answers in advance!
