Problem-relevant configuration.yaml

    ventilation:
      friendly_name: Ventilation
      value_template: "{{ states('switch.fan_low') }}"
      speed_template: "
        {% if is_state('switch.fan_low', 'on') %}
          {% if is_state('switch.fan_medium', 'on') %}

          {% elif is_state('switch.fan_high', 'on') %}
            high
          {% else %}
            low
          {% endif %}
        {% else %}
          off
        {% endif %}
      "
      turn_on:
          - service: switch.turn_on
            entity_id: switch.fan_low
      turn_off:
          - service: switch.turn_off
            entity_id: switch.fan_low
      set_speed:

          - service_template: "{% if speed == 'high' %} switch.turn_on {% else %} switch.turn_off {% endif %}"
            entity_id: switch.fan_high
      speeds:
        - 'off'

Traceback/Error logs

Additional information

I think this might be as simple as allowing the unavailable state.

This is still relevant since PR is not merged yet

I'm seeing this also during startup. My fan is a template from a Z-Wave switch (new Inovelli fan/light combo switch), so it makes sense that it is unavailable while waiting for Z-Wave network to start.
