Read individual cell status with Victron VE.Bus BMS and SmartLithium

Hi, since I see solutions (https://github.com/Louisvdw/dbus-serialbattery) with super cheap BMS devices that show individual cell voltages on the cerbo as well as temperature readings of batteries, I wonder if my victron VE.Bus BMS connected to my two victron SmartLithiums also can offer this information somehow on the cerbo?

I know that I can see it in the app directly red out from the battery itself. My batteries are currently a bit unbalanced and I want to monitor them closely. They are not exactly close by, so a remote readout would be very nice!

Unfortunately this is not possible as the BTV cables connecting the battery to the BMS do not provide this information.

It is ironic that my GX can see the third-party temperature sensors (Ruuvi) and report the info through VRM, but it won’t show me ancillary battery data through the Venus GX or in VRM which I can see with VictronConnect when in BLuetooth range. I know more about the temperature and humidity in my refrigerator than I do my batteries when I am not on the boat…it seems more like a conscious decision not to relay this information to the user than a technical hurdle—at least if the batteries are within Bluetooth range of the Cerbo.
