CANbus BMS manufacturer name

I am trying to make my own BMS with CANbus to communicate with Victron inverter Multiplus-II GX.

For reference I used message IDs used by Pylontech BMS. How can I specify manufacturer name so that it is shown in manufacturer name when checking victrons remote console (on web browser)?

Adding it in CAN message with ID 35E did not help.

I used a MODBUS interface for mine - the BMS code already had a Modbus server, I wrote a d/bus - Modbus interface running under Venus to get the data into the OS.This allows you to put your own BMS name in the appropriate Dbus string.

for CAN bus, it looks like the manufacturer id's are allocated when they subscribe to the standards group, but this is expensive. otherwies trial and error would be the only way...
