State of the Open Smart Home
----------------------------

Today is the `State of the Open Smart Home <https://www.home-assistant.io/state-of-the-open-home/>`__ hosted by Nabu Casa, Home Assistant & ESPHome
and we’ll be joined by our friends from WLED, Z-Wave JS, Stanford’s OVAL lab and Northeastern University to talk about our work on making this vision a reality.

Where: YouTube

When: Today, Saturday, December 11, at 11am PST / 8pm CET

Buttons
-------

This release brings :doc:`buttons </components/button/index>` from Home Assistant. Many times there have been questions on how to simply trigger automations
from the Home Assistant frontend with a button so here you go. Here is a very simple example:

.. code:: yaml

    button:
      - platform: template
        name: Test Button
        on_press:
          then:
            - logger.log: "The button was pressed!!!"

Multiple WiFi networks with static IP
-------------------------------------

This release has a fix that allows using multiple networks each with their own static IP address configuration.
When using these options, you **must** also set ``wifi`` -> ``use_address`` when installing new firmware as ESPHome
cannot know which IP address to use automatically.

The Dashboard and secrets
-------------------------

The ESPHome Dashboard will now save the wifi credentials as secrets (``wifi_ssid`` / ``wifi_password``) for future use. If you are already using these secrets,
then the dashboard will not ask for credentials and will configure using them for you.

The dashboard also now can view the logs straight from a serial connected device via the web browser. It will show up as an option when choosing the method to
view them.

NEC remote protocol
-------------------

In this version, the order of transferring bits was corrected from MSB to LSB in accordance with the NEC standard.
Therefore, if the configuration file has come from an earlier version of ESPhome, it is necessary to reverse
the order of the address and command bits when moving to 2021.12 or above.
For example, address: ``0x84ED``, command: ``0x13EC`` becomes ``0xB721`` and ``0x37C8`` respectively.

Tuya Covers
-----------

:esphomepr:`2637` adds new functionality to the Tuya cover component, but at the same time removes the "soft"
inversion of the direction. Instead, it seems that most if not all tuya covers have a "hidden" datapoint that
sets the direction on the secondary MCU. See the :doc:`documentation </components/cover/tuya>` for the new
configuration options.
