Hello, is there a way to see "time to go/time remaining" (amperage remaining) on the GX touch 50 with Cerbo GX? I have the SmartShunt 500 connected using a VE.direct cable to the Cerbo GX. I can see "time remaining" on my android phone using Victron Connect. Is a BMV-7xx still needed? Thank you, JeffThe MultiPlus 3000 (the inverter in this picture) is connected to the Cerbo using the MK3 USB cable.
