+    :description: Instructions for setting up a Haier climate devices.
+    :image: air-conditioner.svg
+
+The `haier` climate platform creates a Haier climate device.  
+The component can be used as a replacement of a Haier proprietary WiFi modules such as KZW-W001 and KZW-W002.
+
+This component requires a :ref:`uart` to be setup.
+
+.. code-block:: yaml
+
+    logger:
+        baud_rate: 0 #Disable UART logging for ESP8266
+
+    uart:
+        rx_pin: GPIO3
+        tx_pin: GPIO1
+        baud_rate: 9600
+
+    climate:
+        platform: haier
+        name: Haier AC
+        supported_swing_modes:
+          - VERTICAL
+          - HORIZONTAL
+          - BOTH
+
+Configuration variables:
+------------------------
+
+- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
+- **name** (**Required**, string): The name of the climate device.
+- **update_interval** (*Optional*, :ref:`config-time`): How often device will be polled for status. Defaults to `5s`.
+- **supported_swing_modes** (*Optional*, list): List of supported swing modes. Possible values are: ``VERTICAL``, ``HORIZONTAL``, ``BOTH``.
+- All other options from :ref:`Climate <config-climate>`.
+
+Hardware setup
+--------------
+
+Most units will have a dedicated USB-A port for Haier WiFi module.
+The physical USB port is in fact UART and does not "speak" USB protocol.
+It uses four USB pins as 5V, GND, RX, TX. 
+You can use spare male USB cable to connect esphome device directly to the climate appliance.
+
+Other units will not have USB ports, but will still probably have UART exposed somewhere on the main board.
