Combine two switches into one fan with high/low/off on dashboard

Configuration
1

I have two switches that control a fan and its speed, one for on/off and the other for high/low. How can I combine these two switches so they will show up on a dashboard with options high/low/off instead of two separate switches?

Using fan-percent-button-row for my other fans and they look like this

This is how I currently have the two switches on the dashboard, with the speed on=high and off=low

Looks like I can use isTwoSpeedFan to remove the MED option on dashboard.

you can use a template fan. something like this:

fan:
  - platform: template
    fans:
      combined_fan: 
        preset_modes:
          - "Off"
          - "Low"
          - "High"
        preset_mode_template: >
          {% if is_state('switch.fan_power', 'off') %}
            Off
          {% elif is_state('switch.fan_speed', 'on') %}
            High
          {% else %}
            Low
          {% endif %}
        set_preset_mode:
          - choose:
              - conditions:
                  - condition: template
                    value_template: "{{ preset_mode == 'Off' }}"
                sequence:
                  - service: switch.turn_off
                    target:
                      entity_id: 
                        - switch.fan_power
                        - switch.fan_speed
              - conditions:
                  - condition: template
                    value_template: "{{ preset_mode == 'Low' }}"
                sequence:
                  - service: switch.turn_on
                    target:
                      entity_id: switch.fan_power
                  - service: switch.turn_off
                    target:
                      entity_id: switch.fan_speed
              - conditions:
                  - condition: template
                    value_template: "{{ preset_mode == 'High' }}"
                sequence:
                  - service: switch.turn_on
                    target:
                      entity_id: 
                        - switch.fan_power
                        - switch.fan_speed

goes in configuration.yaml

Looks like they changed the config options in the version of HA that I’m on

Invalid config for ‘template’ at configuration.yaml, line 429: ‘fan’ is an invalid option for ‘template’, check: fan

Template fan - Home Assistant doesn’t look to support all the same things either

Thanks for pointing me in the right direction @armedad . The below config works correctly when using the preset modes of the template fan, but not with the custom:fan-percent-button-row entity type. I think it’s because that tries to set the fan speeds, instead of using the preset modes and the speed switch doesn’t get updated. To be continued later…

Tried one last thing for the night. Created a new card like this and got a dropdown with presets that works correctly
image

features:
  - style: dropdown
    type: fan-preset-modes
type: tile
entity: fan.whole_house_fan_template
tap_action:
  action: none
icon_tap_action:
  action: none
show_entity_picture: false
vertical: false
hide_state: true

Figured it out. Had to use a different card type, fan-mode-button-row, for that fan to make it work as I wanted.

  - entity: fan.whole_house_fan_template
    type: **custom:fan-mode-button-row**
    twoModeFan: true
    name: Whole House Fan
