Getting Started with esphomeyaml
|
||
================================
|
||
|
||
esphomeyaml is the perfect solution for creating custom firmwares for
|
||
your ESP8266/ESP32 boards. In this guide we’ll go through how to setup a
|
||
basic “node” in a few simple steps.
|
||
|
||
Installation
|
||
~~~~~~~~~~~~
|
||
|
||
Installing epshomeyaml is very easy. All you need to do is have `Python
|
||
2.7 <https://www.python.org/download/releases/2.7/>`__ installed
|
||
(because of platformio 😕) and install the console script script through
|
||
``pip``.
|
||
|
||
.. code:: bash
|
||
|
||
pip install esphomeyaml
|
||
|
||
Alternatively, there’s also a docker image available for easy
|
||
installation:
|
||
|
||
.. code:: bash
|
||
|
||
docker pull ottowinter/esphomeyaml
|
||
|
||
Creating A Project
|
||
~~~~~~~~~~~~~~~~~~
|
||
|
||
Now let’s setup a configuration file. Fortunately, esphomeyaml has a
|
||
friendly setup wizard that will guide you through creating your first
|
||
configuration file. For example, if you want to create a configuration
|
||
file called ``livingroom.yaml``:
|
||
|
||
.. code:: bash
|
||
|
||
esphomeyaml livingroom.yaml wizard
|
||
# On Docker:
|
||
docker run --rm -v "`pwd`":/config -it ottowinter/esphomeyaml livingroom.yaml wizard
|
||
|
||
At the end of this step, you will have your first YAML configuration
|
||
file ready. It doesn’t do much yet and only makes your device connect to
|
||
the WiFi network and MQTT broker, but still it’s a first step.
|
||
|
||
Adding some features
|
||
~~~~~~~~~~~~~~~~~~~~
|
||
|
||
So now you should have a file called ``livingroom.yaml`` (or similar).
|
||
Go open that file in an editor of your choice and let’s add a `simple
|
||
GPIO switch </esphomeyaml/components/switch/gpio.html>`__ to our app.
|
||
|
||
.. code:: yaml
|
||
|
||
switch:
|
||
- platform: gpio
|
||
name: "Living Room Dehumidifer"
|
||
pin: 5
|
||
|
||
The configuration format should hopefully immediately seem similar to
|
||
you. esphomeyaml has tried to keep it as close to Home Assistant’s
|
||
``configuration.yaml`` schema as possible. In above example, we’re
|
||
simply adding a switch that’s called “Living Room Relay” (could control
|
||
anything really, for example lights) and is connected to pin ``GPIO5``.
|
||
The nice thing about esphomeyaml is that it will automatically also try
|
||
to translate pin numbers for you based on the board. For example in
|
||
above configuration, if using a NodeMCU board, you could have just as
|
||
well set ``D1`` as the ``pin:`` option.
|
||
|
||
First Uploading
|
||
~~~~~~~~~~~~~~~
|
||
|
||
Now you can go ahead and add some more components. Once you feel like
|
||
you have something you want to upload to your ESP board, simply plug in
|
||
the device via USB and type the following command (replacing
|
||
``livingroom.yaml`` with your configuration file):
|
||
|
||
.. code:: bash
|
||
|
||
esphomeyaml livingroom.yaml run
|
||
|
||
You should see esphomeyaml validating the configuration and telling you
|
||
about potential problems. Then esphomeyaml will proceed to compile and
|
||
upload the custom firmware. You will also see that esphomeyaml created a
|
||
new folder with the name of your node. This is a new platformio project
|
||
that you can modify afterwards and play around with.
|
||
|
||
On docker, the first upload is a bit more complicated, either you manage
|
||
to map the serial device into docker with the ``-v`` option, or you just
|
||
call ``compile`` within the container and let platformio do the
|
||
uploading on the host system:
|
||
|
||
.. code:: bash
|
||
|
||
docker run --rm -v "`pwd`":/config -it ottowinter/esphomeyaml livingroom.yaml compile
|
||
platformio run -d livingroom -t upload
|
||
|
||
Now if you have `MQTT
|
||
Discovery <https://www.home-assistant.io/docs/mqtt/discovery/>`__
|
||
enabled in your Home Assistant configuration, the switch should already
|
||
be automatically be added 🎉 (Make sure you’ve added it to a view too.)
|
||
|
||
|image0|
|
||
|
||
After the first upload, you will probably never need to use the USB
|
||
cable again, as all features of esphomelib 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 whether it’s pulled high or low - the `GPIO Binary
|
||
Sensor </esphomeyaml/components/binary_sensor/gpio.html>`__.
|
||
|
||
.. code:: yaml
|
||
|
||
binary_sensor:
|
||
- platform: gpio
|
||
name: "Living Room Window"
|
||
pin:
|
||
number: 16
|
||
inverted: True
|
||
mode: INPUT_PULLUP
|
||
|
||
This is an advanced feature of esphomeyaml, almost all pins can
|
||
optionally have a more complicated configuration schema with options for
|
||
inversion and pinMode - the `Pin
|
||
Schema </esphomeyaml/configuration-types.html#pin-schema>`__.
|
||
|
||
This time when uploading, you don’t need to have the device plugged in
|
||
through USB again. The upload will magically happen “over the air”.
|
||
Using esphomeyaml directly, this is the same as from a USB cable, but
|
||
for docker you need to supply an additional parameter:
|
||
|
||
.. code:: bash
|
||
|
||
esphomeyaml livingroom.yaml run
|
||
# On docker
|
||
docker run --rm -p 6123:6123 -v "`pwd`":/config -it ottowinter/esphomeyaml livingroom.yaml run
|
||
|
||
|image1|
|
||
|
||
Where To Go Next
|
||
~~~~~~~~~~~~~~~~
|
||
|
||
Great 🎉! You’ve now successfully setup your first esphomeyaml project
|
||
and uploaded your first esphomelib 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 `Components
|
||
Index </esphomeyaml/index.html>`__, 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/OttoWinter/esphomeyaml/issues>`__ or contact
|
||
me via the `Discord chat <https://discord.gg/KhAMKrd>`__.
|
||
|
||
Using Custom components
|
||
~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
||
esphomelib’s powerful core makes it easy to create own custom sensors.
|
||
Please first follow the `Custom Sensor Component
|
||
Guide <https://github.com/OttoWinter/esphomelib/wiki/Custom-Sensor-Component>`__
|
||
to see how this can be done. For using custom components with
|
||
esphomeyaml you only need to open up the auto-generated ``src/main.cpp``
|
||
file in the platformio project folder. The lines in between
|
||
``AUTO GENERATED CODE BEGIN`` and ``AUTO GENERATED CODE END`` should not
|
||
be edited and all changes in there will be overriden, but outside of
|
||
those comments you can safely create custom sensors while still using
|
||
esphomeyaml’s great configuration options.
|
||
|
||
.. code:: cpp
|
||
|
||
// Auto generated code by esphomeyaml
|
||
#include "esphomelib/application.h"
|
||
|
||
using namespace esphomelib;
|
||
|
||
void setup() {
|
||
// ===== DO NOT EDIT ANYTHING BELOW THIS LINE =====
|
||
// ========== AUTO GENERATED CODE BEGIN ===========
|
||
App.set_name("cabinet");
|
||
// ...
|
||
// =========== AUTO GENERATED CODE END ============
|
||
// ========= YOU CAN EDIT AFTER THIS LINE =========
|
||
App.setup();
|
||
}
|
||
|
||
void loop() {
|
||
App.loop();
|
||
delay(20);
|
||
}
