Why doesn't the Multi RS Smart provide battery data to Cerbo GX?

I can see that the Multi RS Smart is tracking battery SOC and even providing that to the Cerbo GX, but I'm not able to select it as the battery monitor. Is there any solution for this issue? I know that the Multi RS is new-ish, but this seems like a basic function for something with the Multi name. As seen, the battery field in VRM is blank although all of the information usually listed there is available in the advanced page.

So finally after attempting to install the serial battery driver and a reboot, all of the sudden the battery information is showing on the main page and in the Cerbo GX as expected.

Thanks to all who offered suggestions, I'm not sure why it didn't work initially but possibly it just needed a reboot.

Hi @KW4NP

If you are talking about Settings - DVCC - Controlling BMS, then I may be wrong, but the Multi RS is not a BMS (battery monitor system)...

It has, indeed an internal way, based on battery type, of computing the SoC and autosync/recalibrate with 100% SoC, but it has by no means a BMS function and that is because of the multitude of battery types that can be connected to it.

You can select in the Cerbo only between (true) BMSes.

@Alex Pescaru , I'm not talking about DVCC, I don't need that in my system. I'm talking about the user facing interface that doesn't show the battery information although it is available in the advanced menu.
