What if you added a second shunt in your system? Install it on your 12V battery that supplies the 12V RV house loads. I'm not sure how a second shunt would tie into the Cerbo. Or, even if two shunts could be fed into a Cerbo. But, maybe a BMV-712 shunt that only sees the 12V house system could give you enough data to evaluate your 12V loads. Just a guess.Nope. The shunt is used for SoC and overall amperage calculations. In order to figure out the DC-only loads, the inverters "measure" (poorly) their DC inputs and subtract it from the shunt's value... thus the inaccurate value.
And the kWh graphs are AC-only.
It's still amazing stuff. I do wish I could see/graph/measure my DC side ... I was off-inverter for a while and my DC load consumption was shocking... I need to figure out where it's all going.
Also, just a wild, wild guess based on absolutely NO first-hand knowledge: Could the propane furnaces be using a lot of 12V power? Furnace fans?
