Connecting 3x JKBMS to Cerbo possible?

Hi is it possible to connect 3x JKBMS to a Cerbo for BMS control?

At the moment i just connected them via BT (ESPHome) to HASS, but that just gives me alarms.

Would be nice to get slow down charging and other features as well.
I got three 8S Packs in Parallel. If it's not possible, maybe someone knows other ways to get it to work.

No it is not possible unless they can be daisy chained in comms and have a master and address system like Pylontec or BYD.

You can achieve this by connecting the batteries directly to a GX device and using dbus-serialbattery or by using dbus-mqtt-battery where you can send the data from HASS to Venus OS.

You can both find in my repositories on GitHub: github.com/mr-manuel
