Fan Preset Speeds

Configuration Frontend
1

I managed to make a fan that is % only have 3 presets using a template fan. The presets react to my custom % but it only sets the values to 33, 66, 100, despite what I am trying

- fan:
      - name: "Preset Mode Fan Example"
        state: "{{ states('fan.master_fan_2') }}"
        turn_on:
          - action: fan.turn_on
            target:
              entity_id: fan.master_fan_2
        turn_off:
          - action: fan.turn_off
            target:
              entity_id: fan.master_fan_2
        percentage: >
          {{ state_attr('fan.master_fan_2', 'percentage') }}
        speed_count: 3
        set_percentage:
          - action: fan.set_percentage
            target:
              entity_id: fan.master_fan_2
            data:
              percentage: "{{ percentage }}"
        preset_modes:
          - "off"
          - "low"
          - "medium"
          - "high"
        preset_mode: >
          {% if is_state('fan.master_fan_2', 'on') %}
            {% if state_attr('fan.master_fan_2', 'percentage') == 100  %}
              high
            {% elif state_attr('fan.master_fan_2', 'percentage') == 60 %}
              medium
            {% else %}
              low
            {% endif %}
          {% else %}
            off
          {% endif %}
        set_preset_mode:
          - action: fan.set_percentage
            target:
              entity_id: fan.master_fan_2
            data:
              percentage: >-
                {% if preset_mode == 'high' %}
                  100
                {% elif preset_mode == 'medium' %}
                  60
                {% elif preset_mode == 'low' %}
                  20
                {% else %}
                  0
                {% endif %}

This sets the percentage on the master fan.

This is what percentage is shown in the percent slider.

So you aren’t doing anything with custom percentages outside the preset_modes.

But is that not what this is doing, setting the % based on if I click low/med/high buttons?

set_preset_mode:
          - action: fan.set_percentage
            target:
              entity_id: fan.master_fan_2
            data:
              percentage: >-
                {% if preset_mode == 'high' %}
                  100
                {% elif preset_mode == 'medium' %}
                  60
                {% elif preset_mode == 'low' %}
                  20
                {% else %}
                  0
                {% endif %}

That’s only setting the percentage of fan master 2. The percentage of the template fan is driven by what I listed above.

Well its not setting the percentage of either, and the preset and percentage apply both to the template. The part that you highlighted is also calling out fan_master_2, so I am confused how to have the template change presets.

I basically took this from here: Template - Home Assistant

So I realized that it sort of does work, the drop down menu part does exactly what I want, but the buttons do no:

The dropdown is preset mode and the buttons are percentage.

So, if I put the same logic into the set_percentage, that didn’t seem to read the high, medium, low, so how do those button pushes get recognized? does the “low” button default to 33, and I need to check in the logic if its 33, then set it to 20 for example? I’ll try that

For some reason that clicked and this seems to work, you basically redirect the default 33/66/99 of the buttons to new values.
