ESPHome uses the Arduino framework internally to handle all low-level interactions like
|
||||
initializing the WiFi driver and so on. Unfortunately, every Arduino framework version often
|
||||
has its own quirks and bugs, especially concerning WiFi performance. With the ``arduino_version``
|
||||
option you can tell ESPHome which Arduino framework to use for compiling.

||||
|
||||
.. code-block:: yaml

For the ESP8266, you currently can manually pin the Arduino version to these values (see the full

|

------------------------------
|
||||
|
||||
With this option you can control where the state of certain components is kept on the ESP.
|
||||
Components like ``light``, ``switch``, ``fan`` and ``globals`` can restore their state upon
|
||||
boot.
|
||||
|
||||
However, by default this data is stored in the "RTC memory" section of the ESP8266s. This memory
|
||||
is cleared when the ESP8266 is disconnected from power. So by default the state cannot be recovered
|
||||
after power loss.
|
||||
|
||||
To still have these components restore their state upon power loss the state can additionally be
|
||||
saved in *flash* memory by setting this option to ``true``.
|
||||
|
||||
Beware: The flash has a limited number of write cycles (usually around 100 000), after that
|
||||
the flash section will fail. So do not use this option when you have components that update rapidly.
|
||||
These include GPIO switches that are used internally (disable restoring with the ``restore_mode`` option),
|
||||
certain light effects like ``random`` and the ``on_value_range`` trigger.

|

This behavior can be disabled by setting ``flash_write_interval`` to ``0s`` to immediately commit the state to flash,

however, be aware that this may lead to increased flash wearing and a shortened device lifespan!
