Vaillant VC 246 /calorMatic 430

Hi all
I started from scratch with the integration of a Vailant VC 246 and CalorMatic 430. I managed to receive a lot of information from the sensors, but I can’t figure out how to control it. How can I set the desired hot water temperature? In mqt explorer, I have ebusd/430/HwcTempDesired
and { “value”: {“value”: 40.0}}in configuration.yaml I create

climate:
    - name: "DHW"
      max_temp: 65
      min_temp: 15
      precision: 0.1
      temp_step: 0.5
      modes:
       - "off"
       - "manual"
       - "auto"    
      mode_state_template: >-
          {% set values = { 'off':'off', 'manual':'manual', 'auto':'auto' } %}
          {% set value = value_json.value.value %}
          {{ values[value] if value in values else 'idle' }}
      mode_state_topic: "ebusd/430/HwcOPMode/#"
      mode_command_topic: "ebusd/430/HwcOPMode/set"
      mode_command_template: >-
        {% set values = { 'off':'off', 'manual':'manual', 'auto':'auto'} %}
        {{ values[value] if value in values.keys() else 'off' }}
      temperature_state_topic: "ebusd/430/HwcTempDesired"
      temperature_state_template: '{{value_json["temp"].value}}'
      temperature_command_topic: "ebusd/430/HwcTempDesired/set"
      current_temperature_topic: "ebusd/bai/StorageTemp/#"
      current_temperature_template: '{{value_json["temp"].value}}'

But I get only this. I don’t know how to add buttons to increase and decrease the target temperature.


My configuration.yam entry is probably not entirely correct, but I don’t know what’s wrong.
I would be grateful for any help
