Native API
----------

This release brings with it lots of goodies, but most important is the :doc:`native API </components/api>`.
MQTT has been the only way this project communicated with Home Assistant for a while now. And MQTT is a great protocol
to get started, but it always had problems:

- Another service to install - Users would need to install an MQTT broker in order to get started.
- MQTT Discovery - Home Assistant's MQTT discovery has been great, but always had problems like retained messages etc.
- Inefficient - A typical MQTT message for sending a binary sensor state is about 70 bytes long, and the MQTT library
  we used was quite inefficient with runtime memory allocation too.

So I decided to do something against that: ESPHome now features a native protocol (based on TCP+protocol buffers)
that addresses these issues and has a
`component on the Home Assistant <https://rc--home-assistant-docs.netlify.com/components/esphome/>`__
side too.

**Does this mean MQTT will be removed?**

No! MQTT is an awesome protocol with easy integration for many tools like Node-RED and custom MQTT clients.
This native API is only for replacing communications with Home Assistant, so *if* anything gets removed it's
MQTT auto discovery for Home Assistant. Of course both can be used together at the same time too.

**Should I switch to the native API immediately?**

You definitely can, but a word of warning first: The MQTT implementation has seen tons of fixes for small quirks
in how the ESP SDK works. From my own testing, the native API seems to be quite stable - but I'm sure it'll take a bit
of time to find+fix some final bugs.

**How do I migrate from MQTT?**

First, make sure you run at least Home Assistant 0.85.0 (currently a
`beta release <https://www.home-assistant.io/docs/installation/updating/#run-the-beta-version>`__).
Then, go through the migration guide here (removed).

Python 3 Compatibility
----------------------

PlatformIO has finally implemented `python 3 support <https://github.com/platformio/platformio-core/issues/895>`__
after some quick changes, ESPHome is now also compatible with python 3.5+. So with this new release
you can try ESPHome with Python 3 already. Just make sure to install the development version of platformio first:

.. code-block:: bash

    pip3 install -U https://github.com/platformio/platformio-core/archive/develop.zip

I don't particularly like python 2, and in a year's time support for it will officially be ended. So the plan for
ESPHome is to drop python 2 as soon as possible. Once platformio releases version 4.0 (with python 3 support), I
will go through and check everything still works. Maybe ESPHome will support python 2 for 1 or 2 releases after that
but really I want to drop support for python 2 as soon as possible.

Dashboard & Hass.io Addon Updates
---------------------------------

The dashboard and Hass.io addon have seen a lot of ❤️ in this release: The dashboard has seen tons of small
changes to make the user experience better and the Hass.io addon has been completely re-written with the
`Hass.io Community Addon Images <https://github.com/hassio-addons>`__ as the base.

- The dashboard now features a built-in YAML editor.
- Configuration wizard now shows a list of boards directly, so you just have to choose them from a dropdown.
- Hass.io Addon: You can log in using your Home Assistant credentials now.
- And many more changes (colored logs, auto-scroll, node status, update notifications, ...)

Rename: esphome{lib, yaml} -> ESPHome
-------------------------------------

The name esphomelib and esphomeyaml were too technical, and this project has changed a lot since the first
published release (the yaml part didn't even exist back then). So ... the project is being re-branded slightly:

- esphomeyaml -> ESPHome
- esphomelib -> ESPHome Core
- esphomedocs -> ESPHome Docs

As you see, the yaml project is now getting the "fancy" name, because that's by far the best way to use this framework.
As part of this change, using the _core_ framework directly from code (without YAML) is being deprecated, the API docs
have long been inaccurate now and users should really switch over to ESPHome through YAML

Of course that doesn't mean you won't be able to write custom code. In fact, this release also contains lots of
new guides and changes to make creating custom components much easier. The goal is to have a project where users
can use YAML for the boring boilerplate code but can completely customize everything with custom components.

This migration is of course huge - almost every single file in the code+docs base has esphome{lib, yaml} somewhere
in it, so it will take time until the next release for this to be finished.

Breaking Changes
----------------

- Previously, esphomelib would by default only publish every 15th sensor value in order to provide averaged values.
  However, that often confused users and I now decided to remove it **and** set the default update interval of
  all components to ``60s`` instead of the previous ``15s``. You can get back the old behavior by setting

  .. code-block:: yaml

      sensor:
        - platform: ...  # enter platform here
          # other settings
          update_interval: 15s
          filters:
            - sliding_window_moving_average: {}

- The fastled effects have been renamed to ``addressable_`` for the new
  :doc:`Neopixelbus </components/light/neopixelbus>` integration. See the validation error message
  for more info.

Other notable changes:
----------------------

- You can now configured multiple WiFi networks to connect to. The best one will be chosen automatically.
  This is along with a *complete* rewrite of the WiFi component which now interacts directly with the ESP SDK.
  (:ref:`wifi-networks`)
- GPIO Switches have a new option ``restore_mode`` to configure how their values should be restored on boot.
  (:doc:`/components/switch/gpio`)
- Added :ref:`substitutions <config-substitutions>` to reduce repeating across configs.
- Validation error messages are now displayed even better. Now all errors are shown with the exact context
  where the error appeared. Try it, it's so much better. Next step will be to upgrade to a better YAML reader
  to provide better error messages when the YAML syntax is invalid.
- Added a bunch of guides (and helpers) for creating custom components. Also new: ``esphomeyaml.libraries``,
  ``esphomeyaml.includes`` and ``esphomeyaml.platformio_options`` (:doc:`/components/esphome`)
- Saved a lot of flash space on ESP8266 boards. Previously, platformio would allocate about 1/4 of flash for SPIFFS,
  but esphomelib doesn't use that so now you have that as extra storage. Thanks `@brandond <http://github.com/brandond>`
- You can now use Home Assistant to get time in ESPHome, so no more need for SNTP. See :ref:`time`.
