|
|
|
The ``web_server`` component creates a simple web server on the node that can be accessed
|
|
through any browser and a simple :ref:`api-rest`. Please note that enabling this component
|
|
will take up *a lot* of memory and may decrease stability, especially on ESP8266.

Web server version 3
|
|
|
|
|
|
To navigate to the web server in your browser, either use the IP address of the node or
|
|
use ``<node_name>.local/`` (note the trailing forward slash) via mDNS.
|
|
|
|
|
|
.. code-block:: yaml
|
|
|
|

To conserve flash size, the CSS and JS files used on the root page to show a simple user
|
|
interface are hosted by esphome.io. If you want to use your own service, use the
|
|
``css_url`` and ``js_url`` options in your configuration.
|
|
|
|
Example configurations:
|
|
-----------------------
|
|
|
|
Enabling HTTP authentication:
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Example configuration entry
|
|
web_server:
|
|
port: 80
|
|
auth:
|
|
username: !secret web_server_username
|
|
password: !secret web_server_password
|
|
|
|
Use version 1 user interface:
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Example configuration entry
|
|
web_server:
|
|
port: 80
|
|
version: 1
|
|
|
|
No internet/intranet required on the clients (all assets are inlined, compressed and served from flash):
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Example configuration entry
|
|
web_server:
|
|
local: true
|
|
|
|
|
|
Advanced usage
|
|
--------------
|
|
|
|
The following assume copies of the files with local paths - which are config dependant.
|
|
|
|
Example ``web_server`` version 1 configuration with CSS and JS included from esphome-docs.
|
|
CSS and JS URL's are set to empty value, so no internet access is needed for this device to show it's web interface.
|
|
Force to turn off OTA function because the missing authentication.
|
|
|
|
.. code-block:: yaml
|
|
|
|
web_server:
|
|
port: 80
|
|
version: 1
|
|
ota: false
|
|
css_include: "../../../esphome-docs/_static/webserver-v1.min.css"
|
|
css_url: ""
|
|
js_include: "../../../esphome-docs/_static/webserver-v1.min.js"
|
|
js_url: ""
|
|
|
|
Example ``web_server`` version 2 configuration with JS included from a local file.
|
|
CSS and JS URL's are set to empty value, so no internet access is needed for this device to show it's web interface.
|
|
V2 embeds the css within the js file so is not required, however you could include your own CSS.
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Example configuration entry v2
|
|
web_server:
|
|
js_include: "./v2/www.js"
|
|
js_url: ""
|
|
version: 2
|
|
|
|
Copy https://oi.esphome.io/v2/www.js to a V2 folder in your yaml folder.
|
|
|
|
.. _config-webserver-sorting:
|
|
|
|
Entity sorting
|
|
--------------
|
|
|
|
``web_server`` version 3 supports the sorting of the entitys.
|
|
You can set a ``web_server_sorting_weight`` on each entity.
|
|
Smaller numbers will be displayed first, defaults to 50.
|
|
Example ``sensor`` configuration.
|
|
``My Sensor 2`` is displayed first, then ``My Sensor 1``
|
|
|
|
.. code-block:: yaml
|
|
|
|
sensor:
|
|
- platform: template
|
|
name: "My Sensor 1"
|
|
web_server_sorting_weight: 10
|
|
