:description: Instructions for setting up DF Player Mini component in ESPHome.
:image: dfplayer.svg
The ``dfplayer`` (`datasheet <https://wiki.dfrobot.com/DFPlayer_Mini_SKU_DFR0299>`__), component
allows you to play sound and music stored in an SD card or USB flash drive.

DF-Player mini Module.
For this component to work you need to have set up a :ref:`UART bus <uart>` in your configuration.
Overview
--------
The module can be powered by the 3.3V output of a NodeMCU. For communication you can connect only
the ``tx_pin`` of the ``uart`` bus to the module's ``RX`` but if you need feedback of playback active
you will also need to connect the ``rx_pin`` to the module's ``TX``.
For best quality audio a powered stereo speaker can be connected to the modules ``DAC_R``,
``DAC_L`` and ``GND``, alternatively the module features a built-in 3W audio amplifier, in that case
the pins ``SPK_1`` and ``SPK_2`` should be connected to one passive speaker and a 5V 1A power supply
will be required.
.. code-block:: yaml
# Example configuration entry
dfplayer:
Configuration variables:
------------------------
- **uart_id** (*Optional*, :ref:`config-id`): Manually specify the ID of the UART hub.
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
- **on_finished_playback** (*Optional*, :ref:`Automation <automation>`): An action to be
performed when playback is finished.
``dfplayer.is_playing`` Condition
---------------------------------
This Condition returns true while playback is active.
.. code-block:: yaml
# In some trigger:
on_...:
if:
condition:
dfplayer.is_playing
then:
logger.log: 'Playback is active!'
``dfplayer.play_next`` Action
-----------------------------
Starts playback of next track or skips to the next track.
.. code-block:: yaml
on_...:
then:
- dfplayer.play_next:
``dfplayer.play_previous`` Action
---------------------------------
Plays the previously played track.
.. code-block:: yaml
on_...:
then:
- dfplayer.play_previous:
``dfplayer.play`` Action
------------------------
Plays a track.
.. code-block:: yaml
on_...:
then:
- dfplayer.play:
file: 23
loop: false
# Shorthand
- dfplayer.play: 23
Configuration options:
- **file** (*Optional*, int, :ref:`templatable <config-templatable>`): The global track
number (from all tracks in the device). If not specified plays the first track.
- **loop** (*Optional*, boolean, :ref:`templatable <config-templatable>`): Repeats playing
the same track. Defaults to ``false``.
``dfplayer.play_mp3`` Action
----------------------------
Plays a track inside the folder ``mp3``. Files inside the folder must be numbered from 1
to 9999, like ``0001.mp3``, ``0002.mp3``, ... etc.
The folder name needs to be ``mp3``, placed under the SD card root directory, and the
mp3 file name needs to be 4 digits, for example, "0001.mp3", placed under the mp3 folder.
If you want, you can add additional text after the number in the filename, for example,
``0001hello.mp3``, but must always be referenced by number only in yaml.
.. code-block:: bash
/mp3
/0001hello.mp3
/0002.mp3
/0003_thisistheway.mp3
..
.. code-block:: yaml
on_...:
then:
- dfplayer.play_mp3:
file: 1
# Shorthand
- dfplayer.play_mp3: 1
Configuration options:
- **file** (**Required**, int, :ref:`templatable <config-templatable>`): The file number
inside the ``mp3`` folder to play.
``dfplayer.play_folder`` Action
-------------------------------
Plays files inside numbered folders, folders must be numbered from 1 and with leading
zeros. Like ``01``, ``02``, ... etc. Files inside the folders must be numbered with two
leading zeros, like ``001.mp3``, ``002.mp3``, ... etc.
Folder numbers can range from 1 to 99 and file name from 1 to 255 or folder number
from 1 to 10 and file number from 1 to 1000.
.. code-block:: bash
/01
/001.mp3
/002.mp3
..
/02
/001.mp3
/002.mp3
/003.mp3
..
.. code-block:: yaml
on_...:
then:
- dfplayer.play_folder:
folder: 2
file: 1
Configuration options:
- **folder** (**Required**, int, :ref:`templatable <config-templatable>`): The folder number.
- **file** (*Optional*, int, :ref:`templatable <config-templatable>`): The file number
inside the folder to play. Optional only if ``loop`` is not set.
- **loop** (*Optional*, boolean, :ref:`templatable <config-templatable>`): Repeats playing
all files in the folder. Causes ``file`` to be ignored. Defaults to ``false``.
``dfplayer.set_device`` Action
------------------------------
Changes the device in use. Valid values are ``TF_CARD`` and ``USB``.
.. code-block:: yaml
on_...:
then:
- dfplayer.set_device: TF_CARD
``dfplayer.set_volume`` Action
------------------------------
Changes volume.
.. code-block:: yaml
on_...:
then:
- dfplayer.set_volume:
volume: 20
# Shorthand
- dfplayer.set_volume: 20
Configuration options:
- **volume** (**Required**, int, :ref:`templatable <config-templatable>`): The volume value.
Valid values goes from ``0`` to ``30``.
``dfplayer.volume_up`` Action
-----------------------------
Turn volume up.
.. code-block:: yaml
on_...:
then:
- dfplayer.volume_up
``dfplayer.volume_down`` Action
-------------------------------
Turn volume down.
.. code-block:: yaml
on_...:
then:
- dfplayer.volume_down
``dfplayer.set_eq`` Action
--------------------------
Changes audio equalization preset.
.. code-block:: yaml
on_...:
then:
- dfplayer.set_eq:
eq_preset: ROCK
# Shorthand
- dfplayer.set_eq: ROCK
Configuration options:
- **eq_preset** (**Required**): Eq Preset value. Valid values are ``NORMAL``, ``POP``, ``ROCK``, ``JAZZ``,
``CLASSIC`` and ``BASS``.
``dfplayer.sleep`` Action
-------------------------
Enters sleep mode. Playback is stopped and the action ``dfplayer.set_device: TF_CARD`` should be
send for playback to be enabled again.
.. code-block:: yaml
on_...:
then:
- dfplayer.sleep
``dfplayer.reset`` Action
-------------------------
Module reset.
.. code-block:: yaml

Starts playing a track or resumes paused playback.
.. code-block:: yaml
on_...:

Pauses playback, playback can be resumed from the same position with ``dfplayer.start``.
.. code-block:: yaml
on_...:
then:
- dfplayer.pause
``dfplayer.stop`` Action
------------------------
Stops playback.
.. code-block:: yaml
on_...:
then:
- dfplayer.stop
``dfplayer.random`` Action
--------------------------
Randomly plays all tracks.

- dfplayer.random
All actions
-----------
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID of the DFPlayer if you have multiple components.
Test setup
----------
With the following code you can quickly setup a node and use Home Assistant's service in the developer tools.
E.g. for calling ``dfplayer.play_folder`` select the service ``esphome.test_node_dfplayer_play`` and in
service data enter
.. code-block:: json
{ "file": 23 }
