Victron Device List EG4 LifePower4 Battery Information

Hello,

Asking for help on how to access from Victron Device List my EG4 Battery cell information that show as EG4 in the Victron Device List. I would like to build a widget or a docker-Grafana dashboard in order to display the battery pack cell information. However, I have not been able to find the mapping to the detailed data. Thank you in advance!

Hi @Coalen


My guess would be the detailed data is stored in these dbus paths under com.victronenergy.battery:


/System/NrOfCellsPerBattery
/System/MinCellVoltage
/System/MaxCellVoltage/System/NrOfBatteries


I couldnt find a max and min temperature though:

If you cant spot it I'd maybe try using MQTT-explorer. The MQTT topics correspond with dbus paths. Might help you find those last pieces of data

Hello,

I loaded the MQTT Explorer and have identified the EG4 System in the path as 512. However, I have not been able to figure out how to retrieve the information through Docker & Grafana. What am I missing? Anyones help would be appreciated. See screenshots below.
