Could anyone please help me with the following questions regarding the **Victron Cerbo-S GX** Energy System Control Module:

1. Can I connect the BMV 712 via **VE.Direct** and use the shunt reading to trigger the two relays independently, e.g., low voltage, high voltage?

2. Can the Multiplus 12/1600/70 be connected using a **VE.Bus** connection?

3. The MPPT 250/100 can connect using **VE.Direct**?

4. The Cerbo-S GX can be administered using built-in **bluetooth** and the Victron Connect app?

Many thanks!
