It seems, that you don't have a stable wired connection. Is the serial cable shielded? Anyway, unfortunately you did not read carefully the instructions when opening an issue, but at least you provided the correct logs :-) Here again: 🚨 IMPORTANT 🚨

Oh, I'm terriby sorry. I missed that one. I have installed it now and the error is gone :) But now I have ever device twice. The name of the battery is still the custom one I gave but it shows them twice now: |

I, it seems I was too quick. Now suddenly all three battery banks threw this error at the same time: |

Aggregate Batteries was not able to run (it seems it was supplied NoneType Values). I did a restart for good measure and now it seems to run and aggregate batteries is also running again normally. The strange thing is that all three banks threw the error this time at the same time. If it would be a bad serial connection on bank 1, this should not affect bank 2 or 3 that have not thrown any errors until now? |

It should not be connected, except you are using a USB hub. |
|
Yes, I am using a hub as the cerbo only has two usb ports. Is it possible to connect multiple JK via a single serial adapter? I thought each bms needed its own adapter. Anyways, now it seems to run fine. Thank you very much for your support and this great project! |

In your case you need one UART/TTL port per BMS. The DuPPa.net Isolated 4 port USB to TTL UART FTDI is very stable. |

Describe the bug
I recieved the #8 Internal calculation error two time the last day (fresh setup) with the latest driver version.
First time this occured was yesterday. I connected 1 of my 3 battery banks and after a few minutes (out of the blue) the cerbo beeped and I got this error.
Then I connected all three batteries and it run throughout the night with no problem.
Today I installed aggregate batteries, configured it and used its command to restart serialbattery. Then I got this error again (on the same bank). It runs on a newer hardware version (20230601) of JK than the other two banks (20220701).
The battery now shows state error (not sure how to reset) but otherwise seems to work fine.
How to reproduce
First time: I installed serialbattery on a fresh cerbo gx. Connected 1 battery and after like 10 minutes this error came.
Second time: after installing and configuring aggregate battery and restarting serial battery with their script, banks 2 and 3 were found immediately. Bank 1 took like 30 seconds longer and then when found, threw this error after a few seconds.
Expected behavior
No errors or the ability to clear the error

I saw issue #1110 but there it was requested to open a new issue as this is not a daly bms when another person mentioned they got the same issue on jk.
