Config file

[dmsims]

Currently each time there is a new release various values may have to be edited including Board type, Cell count, voltages, BLE MAC etc

Consider putting these variables into a config file?

[Sleeper85]

The main YAML is your config file, I try not to make too many changes to keep it compatible but I admit that often there are changes.
I will think about this question.

[Sleeper85]

I just did a first test and there are several possibilities to do this.

But really you just need to keep and reuse your main YAML and replace the packages folder.
Putting information elsewhere in another file won't change much if I change or add an option, you'll need to edit your config file in that case.

[Sleeper85]

Create a yambms_config.yaml file with your settings.

Example yambms_config.yaml

substitutions:
  config_bms1_option1: 'option1'
  config_bms2_option1: 'option1'
  config_yambms1_yambms_id: 'yambms1'
  config_yambms1_canbus_id: 'canbus1'
  config_canbus1_option1: 'option1'

Import it and replace in the main YAML the values ​​with the substitution variables from your config file.

Example yambms_main.yaml

packages:
  # Your config files
  yambms_config: !include yambms_config.yaml
  #
  device_base: !include packages/base/device_base.yaml
  device_board: !include packages/board/board_esp32-devkit-v1.yaml
  
  yambms1: !include
    file: packages/yambms/yambms.yaml
    vars:
      yambms_id: ${config_yambms1_yambms_id}
      yambms_name: ${config_yambms1_canbus_id}

I don't know what to think about it, it adds complexity in some cases unnecessary and this could also allow to maintain several YamBMS based on the same config file and change options in one place.

In both cases, both styles can exist, either enter the values ​​directly in the main file or use a config file.
