Multiple entities and grouping with different calculation modes

I´ve added multiple entities with different fixed calculation values to a group and wanted it to create a summary entity. The summary entity just uses the power consumption of last added entity and ignores the rest. In the first place the summary entity showed Unknown as value, i removed the create_group and then added it again, after that the problem above showed up.

This is my config.

sensor:
  - platform: powercalc
    create_group: All heaters
    entities:
      - entity_id: switch.heizung_working_room_on_off
        name: Arbeitszimmer
        fixed:
          power: 900
      - entity_id: switch.heizung_bad_on_off
        name: Bad
        fixed:
          power: 450
      - entity_id: switch.heizung_schlafzimmer_on_off
        name: Schlafzimmer
        fixed:
          power: 580
      - entity_id: switch.heizung_flur_on_off
        name: Flur
        fixed:
          power: 580
      - entity_id: switch.heizung_living_room_on_off
        name: Wohnzimmer
        fixed:
          power: 900

Will be fixed with #304

@nicodoerr Was able to reproduce the issue with name properties. I have some ideas how to fix it, however the fix is far from simple. Have some unwanted side effects with a few things I tried. Not sure if I will fix it at all because it is really an edge case, which I don’t think many users will experience.

The bug will arise when the source entity has a unique id. The energy sensor will also be created with this unique id. When you change the name later on the energy sensor will keep the old entity_id (this is because the energy sensor has a unique id). The group sensors will refer to the new entity_id so that’s why they are broken.
