Purchase Advice Request - I am trying to troubleshoot a parasitic drain on a two battery system

I have a 2024 RAM diesel with 2 flooded battery parallel 12 volt system. The issue is occasionally (once in a month, for the past two months) the batteries drain overnight. Is the solution to install a shunt on each battery connected to a CERBO GX that can send an alert to the App when the battery voltage falls below 12.4 volts?
Bluetooth will not extend into the house, so I have determined I will need to CERBO GX for the Wi-Fi communication link. Do I need a BMV-712 to complete the system?

Thank you for your advice
