Smart IP43 Charger with VRM/Venus os on Rasperry Pi

I’m new to Victron equipment and have done a lot of research with some success. I’ll keep this brief since I have plenty of gear: a MultiPlus charger/inverter, several models of Smart MPPT solar chargers, a Smart IP43 charger, a Cerbo GX, and a Raspberry Pi running Venus OS. I’ve watched many YouTube videos on setting up monitoring, but I have a question: why isn’t the Smart IP43 charger displaying properly on my Raspberry Pi setup, even though it works well with the Cerbo GX?
