Checklist

• I have read the FAQ to see if there is a known solution to my problem.
• I have enabled debug logging for my installation.
• I have filled out the issue template to the best of my ability.
• This issue only contains 1 issue (if you have multiple issues, open one issue for each issue).
• This issue is not a duplicate issue of currently previous issues..

Describe the issue

powercalc:
  sensors:
    - create_group: klo_net_power
      group_type: subtract
      entity_id: sensor.klo_socket_circuit_power
      subtract_entities: 
        - entity_id: sensor.r_office_right_plug_current_power
        - entity_id: sensor.r_office_left_plug_current_power

Generates the following warning:

Configuration warnings
Invalid config for 'powercalc' at configuration.yaml, line 36: value should be a string 'powercalc->sensors->0->subtract_entities->0', got {'entity_id': 'sensor.r_office_right_plug_current_power'}
Invalid config for 'powercalc' at configuration.yaml, line 37: value should be a string 'powercalc->sensors->0->subtract_entities->1', got {'entity_id': 'sensor.r_office_left_plug_current_power'}

Using the same entities, I am able to create the group in the GUI

I also tried this configuration, which doesn't generate the errors but also doesn't work (entity not created by Powercalc).

powercalc:
  sensors:
    - create_group: klo_net_power
      group_type: subtract
      entity_id: sensor.klo_socket_circuit_power
      subtract_entities: 
        - sensor.r_office_right_plug_current_power
        - sensor.r_office_left_plug_current_power

Reproduction steps

1. Create yaml file
2. Developer Tools
3. Check Configuration
   ...

Debug logs

I didn't see anything in the logs since I didn't proceed further with a restart when I saw the configuration error.

Diagnostics dump or YAML config

No response

Your first example was wrong indeed.

subtract_entities should be a list, like in your second example.

powercalc:
  sensors:
    - create_group: klo_net_power
      group_type: subtract
      entity_id: sensor.klo_socket_circuit_power
      subtract_entities: 
        - sensor.r_office_right_plug_current_power
        - sensor.r_office_left_plug_current_power

Not sure why no entity is created, this should work.
Did you enable debug logs and check that logs after startup?

[bramstroker]

I see the docs were wrong btw, so that's why you used wrong configuration.
That will be updated. https://docs.powercalc.nl/sensor-types/group/subtract/

Thanks for having a look. I'll try with the second method again. Maybe that's when I messed up the indentation or something.
