+E1.31
+*****
+
+This effect enables controlling addressable lights using UDP-based
+E1.31_ protocol.
+
+JINX_ can be used to control E1.31_ enabled ESPHome.
+
+.. code-block:: yaml

+    e131:
+      method: multicast # default: register E1.31 to Multicast group

+          - e131:
+              universe: 1
+              channels: RGB
+
+Configuration variables:
+
+- **method** (*Optional*): Listening method, one of ``multicast`` or ``unicast``. Defaults to ``multicast``.
+- **universe** (*Required*, integer): The value of universe, between 1 to 512.
+- **channels** (*Optional*): The type of data. This is used to specify if it is a ``MONO``,
+  ``RGB`` or ``RGBW`` light and in which order the colors are. Defaults to ``RGB``.
+
+There are three modes of operation:
+
+- `MONO`: this supports 1 channel per LED (luminance), up-to 512 LEDs per universe
+- `RGB`: this supports 3 channels per LED (RGB), up-to 170 LEDs (3*170 = 510 bytes) per universe
+- `RGBW`: this supports 4 channels per LED (RGBW), up-to 128 LEDs (4*128 = 512 bytes) per universe
+
+If there's more LEDs than allowed per-universe, additional universe will be used.
+In the above example of 189 LEDs, first 170 LEDs will be assigned to 1 universe,
+the rest of 19 LEDs will be automatically assigned to 2 universe.
+
+It is possible to enable multiple light platforms to listen to the same universe concurrently,
+allowing to replicate the behaviour on multiple strips.

+Adalight
+********
+
+This effect enables controlling addressable lights using UART-based
+Adalight_ protocol, allowing to create realtime ambient lighting effects.
+
+Prismatik_ can be used to control addressable lights via Adalight_ protocol
+on ESPHome.

+
+    # Example configuration entry

+    logger:
+      baud_rate: 0

+              # uart_id: additional_uart
+
+Configuration variables:

+- **uart_id** (*Optional*, :ref:`config-id`): Manually specify the ID of the :ref:`UART Component <uart>` if you want
+  to use multiple UART buses.

+WLED
+****
+
+This effect enables controlling addressable lights using UDP-based
+`UDP Realtime Control`_ protocol used by WLED_, allowing to create realtime ambient
+lighting effects.
+
+Prismatik_ can be used to control addressable lights over network on ESPHome.
+
+.. code-block:: yaml
+
+    wled:
+
+    light:
+      - platform: neopixelbus

+        effects:
+          - wled:
+              # port: 21324
+
+Configuration variables:
+
+- **port** (*Optional*, integer): The port to run the UDP server on. Defaults to ``21324``.
+
+Currently the following realtime protocols are supported:
+WARLS, DRGB, DRGBW, DNRGB and WLED Notifier.
