Template switch with multiple actions

I am trying to set up a switch by template to perform multiple actions on turn_on and turn_off. The value_template is working but I can’t get any actions to run. Any ideas, please?

    immersion1:
      friendly_name: "Immersion 1"
      unique_id: immersion1
      value_template:  "{{ is_state('climate.immersion_1_thermostat','on') }}"
      turn_on:
        - action: climate.set_preset_mode
          target:
            entity_id: climate.immersion_1_thermostat
          data:
            preset_mode: home
        - action: climate.turn_on
          data: {}
          target:
            entity_id: climate.immersion_1_thermostat
      turn_off:  
        - action: climate.set_preset_mode
          data:
            preset_mode: away
          target:
            entity_id: climate.immersion_1_thermostat
        - action: climate.turn_off
          data: {}
          target:
            entity_id: climate.immersion_1_thermostat

:thinking:

- switch:
    - name: Immersion 1
      unique_id: immersion1
      icon: mdi:water-boiler
      state: "{{ is_state('climate.immersion_1_thermostat','on') }}"
      turn_on:
        - service: climate.set_preset_mode
          target:
            entity_id: climate.immersion_1_thermostat
          data:
            preset_mode: home
        - service: climate.turn_on
          target:
            entity_id: climate.immersion_1_thermostat
      turn_off:
        - service: climate.set_preset_mode
          target:
            entity_id: climate.immersion_1_thermostat
          data:
            preset_mode: away
        - service: climate.turn_off
          target:
            entity_id: climate.immersion_1_thermostat

value_template: > state: (new format)

- action: > - service:

It’s the other way around action is the current key. They also need to add the platform: template key and value.

switch:
  - platform: template
    switches:
      immersion1:
        value_template: "{{ is_state('switch.source', 'on') }}"
        turn_on:
          - action: switch.turn_on
            target:
              entity_id: switch.target
          - action: light.turn_on
            target:
              entity_id: light.target
            data:
              brightness_pct: 40
        turn_off:
          - action: switch.turn_off
            target:
              entity_id: switch.target
          - action: light.turn_off
            target:
              entity_id: light.target

My configuration.yaml file contains the following line:
switch: !include switch.yaml
and the lines that I posted were cut out of my switch.yaml file which contains plenty of switches that work:

- platform: template

I actually used the HA page that you mentioned Template Switch - Home Assistant as the basis for code.

This is really confusing me as I have an automation which delivers the desired outcome and I just wanted a simple “manual” option for my dashboard.

So,after building some screens, it looks like the switch works insofar as it turns the immersion heater on, but the displayed status of the climate helper doesn’t reflect that.


So what I really need to achieve is to get the climate helper and card to reflect the current situation.
This looks a lot like this thread Thermostat Card Buttons Not Updating? so I probably need to close this one and head on over there. Thanks.
