:description: Getting Started guide for installing ESPHome as a Home Assistant add-on and creating a basic configuration.

|
||
|
||
ESPHome is the perfect solution for creating custom firmware for
|
||
your ESP8266/ESP32 boards. In this guide we’ll go through how to setup a
|
||
basic "node" by use of the Home Assistant add-on.
|
||
|
||
But first, here's a very quick introduction to how ESPHome works:
|
||
ESPHome is a *tool* which reads in a YAML configuration file (just like Home Assistant)
|
||
and creates a custom firmware binary. The tool also has many helpers that simplify flashing devices (uploading the new binary file)
|
||
and aim to make managing your ESP boards as simple as possible. Once you have added devices
|
||
or sensors in ESPHome's configuration, they will even automatically show up in Home
|
||
Assistant's UI.
|
||
|
||
Installation
|
||
------------
|
||
|
||
Installing the ESPHome Home Assistant add-on is easy. Just navigate to the Supervisor
|
||
panel in your Home Assistant frontend and add the ESPHome add-on repository:
|
||
https://github.com/esphome/hassio
|
||
|
||
.. figure:: images/hassio_repo.png
|
||
|
||
Then, scroll down and locate the ESPHome Home Assistant add-ons section. Click on ESPHome, then INSTALL.
|
||
|
||
.. figure:: images/hassio_addons_section.png
|
||
|
||
After that, wait a bit until the add-on is installed (this can take a while) and
|
||
go to the add-on page. Start the add-on and then click "Open Web UI".
|
||
|
||
.. figure:: images/hassio_addon.png
|
||

|
||
:width: 75.0%
|
||
|
||
You should now be greeted by a nice introduction wizard which will step you through
|
||
creating your first configuration.
|
||
|
||

|
||
|
||
Dashboard Interface
|
||
-------------------
|
||
|
||
Assuming you created your first configuration file with the wizard, let's take a quick
|
||
tour of the ESPHome dashboard interface.
|
||
|
||
.. figure:: images/hassio_interface.png
|
||
:align: center
|
||
:width: 95.0%
|
||
|
||
On the front page you will see all configurations for nodes you created. For each file,
|
||
there are three basic actions you can perform:
|
||
|
||
- **UPLOAD**: This compiles the firmware for your node and uploads it using any connected
|
||
USB device or, if no USB devices are connected, over-the-air using the :doc:`/components/ota`.
|
||
|
||
.. warning::
|
||
|
||
The Home Assistant add-on is currently not capable of discovering new USB ports after the
|
||
add-on has started due to some docker restrictions. Please go to the add-on details page
|
||
and restart the add-on if a new USB device is not automatically found. If the USB device
|
||
is still not found, try changing the USB cable and restarting the add-on.
|
||
|
||
- **SHOW LOGS**: With this command you can view all the logs the node is outputting. If a USB device is
|
||
connected, it will attempt to use the serial connection. Otherwise it will use the built-in OTA logs.
|
||
|
||
- **COMPILE**: This command compiles the firmware and gives you the option of downloading the generated
|
||
binary so that you can upload it yourself from your computer.
|
||
|
||
.. note::
|
||
|
||
If you're having problems with flashing over USB, you can always download the firmware using the
|
||
``COMPILE`` button and flash the firmware using :ref:`ESPHome-flasher <esphome-flasher>`.
|
||
|
||
The configuration files for ESPHome can be found and edited under ``<HOME_ASSISTANT_CONFIG>/esphome/``.
|
||
For example the configuration for the node in the picture above can be found
|
||
in ``/config/esphome/livingroom.yaml``.
|
||
|
||
Now go ahead and use one of the :ref:`devices guides <devices>` to extend your configuration for the device you
|
||
intend to flash an ESPHome firmware onto. Then proceed with uploading the first firmware using the
|
||
upload button.
|
||
|
||
Adding some (basic) features
|
||
----------------------------
|
||
|
||
So now you should have a file called ``/config/esphome/livingroom.yaml`` (or similar).
|
||
Go open that file (in any text editor) and add a :doc:`simple GPIO switch </components/switch/gpio>`
|
||
to the configuration like this:
|
||
|
||
.. code-block:: yaml
|
||
|
||
switch:
|
||
- platform: gpio
|
||
name: "Living Room Dehumidifier"
|
||
pin: 5
|
||
|
||
In above example, we're simply adding a switch that's called "Living Room Dehumidifier" (could control
|
||
anything really, for example lights) and is connected to the pin ``GPIO5``.
|
||
|
||
Now when you go to the Home Assistant "Integrations" screen (under "Configuration" panel), you
|
||
should see the ESPHome device show up in the discovered section (although this can take up to 5 minutes).
|
||
Alternatively, you can manually add the device by clicking "CONFIGURE" on the ESPHome integration
|
||
and entering "<NODE_NAME>.local" as the host.
|
||
|
||
.. figure:: /components/switch/images/gpio-ui.png
|
||
:align: center
|
||
:width: 75.0%
|
||
|
||
After the first upload, you will probably never need to use the USB
|
||
cable again, as all features of ESPHome are enabled remotely as well.
|
||
No more opening hidden boxes stowed in places hard to reach. Yay!
|
||
|
||
Adding A Binary Sensor
|
||
----------------------
|
||
|
||
Next, we’re going to add a very simple binary sensor that periodically
|
||
checks a GPIO pin to see whether it’s pulled high or low - the :doc:`GPIO Binary
|
||
Sensor </components/binary_sensor/gpio>`.
|
||
|
||
.. code-block:: yaml
|
||
|
||
binary_sensor:
|
||
- platform: gpio
|
||
name: "Living Room Window"
|
||
pin:
|
||
number: 16
|
||
inverted: True
|
||
mode: INPUT_PULLUP
|
||
|
||
This is an advanced feature of ESPHome, almost all pins can
|
||
optionally have a more complicated configuration schema with options for
|
||
inversion and pinMode - the :ref:`Pin Schema <config-pin_schema>`.
|
||
|
||
This time when uploading, you don’t need to have the device plugged in
|
||
through USB again. The upload will magically happen :doc:`"over the air" </components/ota>`.
|
||
|
||

|
||
|
||
Where To Go Next
|
||
----------------
|
||
|
||
Great 🎉! You’ve now successfully setup your first ESPHome project
|
||
and uploaded your first ESPHome custom firmware to your node. You’ve
|
||
also learned how to enable some basic components via the configuration
|
||
file.
|
||
|
||
So now is a great time to go take a look at the :doc:`Components Index </index>`.
|
||
Hopefully you’ll find all sensors/outputs/… you’ll need in there. If you’re having any problems or
|
||
want new features, please either create a new issue on the `GitHub issue
|
||
tracker <https://github.com/esphome/issues/issues>`__ or find us on the
|
||
`Discord chat <https://discord.gg/KhAMKrd>`__ (also make sure to read the :doc:`FAQ <faq>`).
