6 months ago Enable debugging in the config file and check the parameters page in the GUI.
If you have the voltages of SOC_RESET_VOLTAGE and MAX_CELL_VOLTAGE only 0.001 V apart the test is not very useful, since the values are rounded. Try at least 0.01 V difference between the values.
Your log does even say that it cannot connect to the battery, therefore it's strange that you can see even data in the GUI.
If the config.default.ini would be truncated then the driver won't even start as above and throw a lot of errors.

Describe the problem
Probably a user error, but here's what I encounter.
I'm unable to get the system to charge to SOC_RESET_VOLTAGE as this voltage needs to be higher than MAX_CELL_VOLTAGE, at which the Victron system stops charging. I've set both values at 0.001v apart and the battery sees that voltage regularly for a few seconds but no reset.
I also tried raising the voltages, thus charging the batteries, then lovering them and rebooting the Cerbo. This causes the cells to be higher then SOC_RESET_VOLTAGE for a few minutes but still no reset.

Config file
Relevant log output
Any other information that may be helpful
This might be completely irrelevant but when I'm opening config.default.ini externally, via file explorer in "MeshCentral", the file starts at:
d on dbus [Valid values 0,1,2,3] ; 0 Do not publish all the cells (only the min/max cell data as used by the default GX) ; 1 Format: /Voltages/Cell (also available for display on Remote Console) ; 2 Format: /Cell/#/Volts ; 3 Both formats 1 and 2 BATTERY_CELL_DATA_FORMAT = 1
All text above this is just missing. If I open the file (via SSH) locally on the Cerbo, the whole file is there so probably just an issue with MeshCentral.
