Understanding How dbus-serialbattery and dbus-aggregate-batteries Work Together

[James-Lee-007]

Hello, I'm seeking assistance in understanding the interaction between the dbus-serialbattery driver and the dbus-aggregate-batteries driver developed by Dr-Gigavolt. I've successfully connected two JK BMSs to my Cerbo GX using dbus-serialbattery and aggregated them using dbus-aggregate-batteries. The aggregated battery is correctly displayed in my device list on Cerbo GX.

However, I'm confused about a few aspects of how these drivers work together and affect the system's configuration:

Configuration Inheritance: The dbus-serialbattery documentation mentioned that to aggregate multiple batteries, one could use additional drivers like dbus-aggregate-batteries. I've done this, but it's unclear whether the configuration changes I've made in the config.ini for dbus-serialbattery apply to the aggregated battery. How does the configuration from dbus-serialbattery interact with the aggregated battery setup?

OWN_CHARGE_PARAMETERS Setting: I noticed the OWN_CHARGE_PARAMETERS option in the settings.py file of the dbus-aggregate-batteries driver. What exactly does setting OWN_CHARGE_PARAMETERS to false do? How does it influence the behavior of the aggregated battery, especially in relation to charge parameters defined elsewhere?

DVCC Page Configuration on Venus OS: When setting up the controlling BMS in the DVCC page of Venus OS, should I select the AggregateBattery created by dbus-aggregate-batteries or one of the individual SerialBatteries (JK BMSs)?

I'd appreciate any guidance or references to further documentation on these points.

Thank you in advance for your assistance!

The config of the dbus-serialbattery driver is only used for the driver itself. Please ask your question in the aggregator repository you are using, since the dbus-serialbattery does not communicate with the aggregator. The aggregator fetches the data from dbus-serialbattery and dbus-serialbattery is not aware that there is an aggregator.
