VW Connect & Homekit Integration

Hello everyone,

I am still relatively new to the Home Assistant universe and am currently working on implementing my first projects. I would like to integrate some controls and information from the VW Connect adapter into Apple HomeKit. This already works without any problems with switches and locks. Now I would like to have the battery level and cruising range displayed as well, but this is proving to be not so easy.

# Loads default set of integrations. Do not remove.
default_config:

# Load frontend themes from the themes folder
frontend:
  themes: !include_dir_merge_named themes

automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml

# configuration.yaml

template:
  - sensor:
    - unique_id: id5_battery_for_homekit
      name: "ID.5 Batterie"
      unit_of_measurement: "%"
      device_class: battery
      state: "{{ states('sensor.***_battery_level') | float(0) }}"
    - name: "ID.5 Reichweite"
      unit_of_measurement: "km"
      device_class: distance
      state: "{{ states('sensor.***_battery_cruising_range') | float(0) }}"
      unique_id: id5_battery_cruising_range

Has anyone already done this, or can you give me some advice on what else I could do?
