OTA Update Component

:description: Instructions for setting up Over-The-Air (OTA) updates for ESPs to upload firmwares remotely.

|
||
|
||
With the OTA (Over The Air) update component you can upload your
|
||
firmware binaries to your node without having to use an USB cable for
|
||
uploads. esphomeyaml natively supports this through its ``run`` and
|
||
``upload`` helper scripts.
|
||
|
||
.. note::
|
||
Please be aware that ESP8266 modules must be reset after a serial
|
||
upload before OTA can work.
|
||
When you are trying to conduct an OTA update and receive an error message
|
||
``Bad Answer: ERR: ERROR[11]: Invalid bootstrapping`` the reason is
|
||
very likely that power-cycling the ESP module is required once after
|
||
the serial upload.
|
||
|
||
|
||
Optionally, you can also define a password to use for OTA updates so
|
||
that an intruder isn’t able to upload any firmware to the ESP without
|
||
having hardware access to it. This password is also hashed
|
||
automatically, so an intruder can’t extract the password from the
|
||
binary.
|
||
|
||
esphomelib also supports an “OTA safe mode”. If for some reason your
|
||
node gets into a boot loop, esphomelib will automatically try to detect
|
||
this and will go over into a safe mode after 10 unsuccessful boot
|
||
attempts. In that mode, all components are disabled and only Serial
|
||
Logging+WiFi+OTA are initialized, so that you can upload a new binary.

# Example configuration entry
|
||
ota:
|
||
safe_mode: True
|
||
password: VERYSECURE
|
||
|
||
Configuration variables:
|
||
------------------------
|
||
|
||
- **safe_mode** (*Optional*, boolean): Whether to enable safe mode.
|
||
Defaults to ``True``.
|
||
- **password** (*Optional*, string): The password to use for updates.
|
||
- **port** (*Optional*, int): The port to use for OTA updates. Defaults
|
||
to ``3232`` for the ESP32 and ``8266`` for the ESP8266.
|
||
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
|
||
|
||
.. note::
|
||
|
||
If you get errors like
|
||
|
||
.. code::
|
||
|
||
ERROR [esphomeyaml.espota] Failed
|
||
ERROR [esphomeyaml.espota] Host livingroom.local Not Found
|
||
|
||
when attempting to upload via OTA, please try setting a :ref:`manual IP for WiFi <wifi-manual_ip>`.
