+The :ref:`I²C Bus <i2c>` is required to be set up in your configuration for this sensor to work.
+
+Example sensors:
+
+.. code-block:: yaml
+
+    # Example configuration entry
+    sensor:
+      - platform: honeywell_hih_i2c
+        temperature:
+          name: "Living Room Temperature"
+        humidity:
+          name: "Living Room Humidity"
+
+Configuration variables:
+------------------------
+
+- **temperature** (**Required**): The information for the temperature sensor.
+  All options from :ref:`Sensor <config-sensor>`.
+
+- **humidity** (**Required**): The information for the humidity sensor.
+  All options from :ref:`Sensor <config-sensor>`.
+
+- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the sensor. Defaults to ``60s``.
