+ESP32 RMT LED Strip
+===================
+
+.. seo::
+    :description: Instructions for setting up addressable lights like NEOPIXEL on an ESP32 using the RMT peripheral.
+    :image: color_lens.svg
+
+This is a component using the ESP32 RMT peripheral to drive most addressable LED strips.
+
+.. code-block:: yaml
+
+    light:
+      - platform: esp32_rmt_led_strip
+        rgb_order: GRB
+        pin: GPIO13
+        num_leds: 30
+        rmt_channel: 0
+        chipset: ws2812
+        name: "My Light"
+
+Configuration variables
+-----------------------
+
+- **pin** (**Required**, :ref:`config-pin`): The pin for the data line of the light.
+- **num_leds** (**Required**, int): The number of LEDs in the strip.
+- **rmt_channel** (**Required**, int): The RMT channel to use. If using multiple strips, you need to use different channels.
+    - **ESP32**: ``0`` to ``7``
+    - **ESP32-S2**: ``0`` to ``3``
+    - **ESP32-S3**: ``0`` to ``3``
+    - **ESP32-C3**: ``0`` or ``1``
+
+- **chipset** (**Required**, enum): The chipset to apply known timings from. Not used if specifying the timings manually, see below.
+    - ``WS2812``
+    - ``SK6812``
+    - ``APA106``
+    - ``SM16703``
+
+- **rgb_order** (**Required**, string): The RGB order of the strip.
+    - ``RGB``
+    - ``RBG``
+    - ``GRB``
+    - ``GBR``
+    - ``BGR``
+    - ``BRG``
+
+- **is_rgbw** (*Optional*, boolean): Set to ``true`` if the strip is RGBW. Defaults to ``false``.
+- **max_refresh_rate** (*Optional*, :ref:`config-time`):
+  A time interval used to limit the number of commands a light can handle per second. For example
+  16ms will limit the light to a refresh rate of about 60Hz. Defaults to sending commands as quickly as
+  changes are made to the lights.
+
+Manual Timings
+**************
+
+These can be used if you know the timings and your chipset is not set above. If you have a new specific chipset,
+please consider adding support to the codebase and add it to the list above.
+
+- **bit0_high** (*Optional*, :ref:`config-time`): The time to hold the data line high for a ``0`` bit.
+- **bit0_low** (*Optional*, :ref:`config-time`): The time to hold the data line low for a ``0`` bit.
+- **bit1_high** (*Optional*, :ref:`config-time`): The time to hold the data line high for a ``1`` bit.
+- **bit1_low** (*Optional*, :ref:`config-time`): The time to hold the data line low for a ``1`` bit.
