Template problem with MQTT

Configuration
1

Hi. I have a problem with the following template. Basically what it should do is updating input_select when a value of particular MQTT topic changes and updating the MQTT topic when input_select value is changed in HA. Unfortunately none of this seems to work - it just keeps both MQTT topic and input select on “Automatic”
Manually submitting the value to MQTT topic works fine.

  - alias: Set Central Heating Operation Mode
    initial_state: on
    trigger:
      - platform: state
        entity_id: input_select.central_heating_operation_mode
    action:
      service: mqtt.publish
      data_template:
        topic: "ebusd/f47/Hc1OPMode/set"
        payload: >
          {% if is_state('input_select.central_heating_operation_mode','Automatic') %}
          auto
          {% elif is_state('input_select.central_heating_operation_mode','Night') %}
          night
          {% elif is_state('input_select.central_heating_operation_mode','Comfort') %}
          comfort
          {% elif is_state('input_select.central_heating_operation_mode','Summer') %}
          summer
          {% endif %}

  - alias: Get Central Heating Operation Mode
    initial_state: on
    trigger:
      - platform: mqtt
        topic: "ebusd/f47/Hc1OPMode"
    action:
      service: input_select.select_option
      data_template:
        entity_id: input_select.central_heating_operation_mode
        option: >
          {% set opmode = {
            'auto': 'Automatic',
            'night': 'Night',
            'comfort': 'Comfort',
            'summer': 'Summer' } %}
          {{ opmode.get('trigger.payload','Automatic') }}
