Victron - which sensors to use for SoC, PV power, EV charger status and current, essential load power

Hi all,

I’m getting started with the Home Assistant integration for Victron. My setup: single phase home, a PV inverter (SAJ), connected to the Victron Multiplus II system, a home battery, Victron EV Charger and Victron Cerbo GX.

I want to optimise the use of excess PV power (home battery full and more PV power supplied compared to demand of the home) and put this in the car.

To do so I need to know:

  • the home battery SoC
  • the PV supplied power
  • the power demand of the house
  • the current or power consumed by the EV charger
  • the state of the EV charger

I’m using the Victron integration via HACS. After configuring the integration, I have 6 devices and hundreds of sensors.

For the battery SoC alone, I have 3 potential candidates:
sensor.system_battery_soc
sensor.battery_soc
sensor.ebus_soc

Which one should I pick?

Which sensors do I need to use for the remaining?

Thanks for your pointers!
