The ``speed`` fan platform lets you represent any float :ref:`output` as a fan that
supports speed settings.

# Example configuration entry
fan:
- platform: speed
output: my_output_1
name: "Living Room Fan"
Configuration variables:
------------------------
- **output** (**Required**, :ref:`config-id`): The id of the :ref:`float output <output>` to use for this fan.
- **oscillation_output** (*Optional*, :ref:`config-id`): The id of the
:ref:`output <output>` to use for the oscillation state of this fan. Default is empty.
- **direction_output** (*Optional*, :ref:`config-id`): The id of the
:ref:`output <output>` to use for the direction state of the fan. Default is empty.
- **speed_count** (*Optional*, int): Set the number of supported discrete speed levels. The value is used
to calculate the percentages for each speed. E.g. ``2`` means that you have 50% and 100% while ``100``
will allow 1% increments in the output. Defaults to ``100``.
- **preset_modes** (*Optional*): A list of preset modes for this fan. Preset modes can be used in automations (i.e. `on_preset_set`).
- All other options from :ref:`Fan Component <config-fan>`.
