+The XGZP68xx Differential Pressure sensor allows you to use digital differential pressure sensors such as the 6899D
+(`datasheet <https://cfsensor.com/wp-content/uploads/2022/11/XGZP6899D-Pressure-Sensor-V2.8.pdf>`__) or 
+6897D Series (`datasheet <https://cfsensor.com/wp-content/uploads/2022/11/XGZP6897D-Pressure-Sensor-V2.7.pdf>`__)
+sensors with ESPHome. The sensors pressure ranges are specified in the datasheets.
+
+Calibrating the sensor can be done by checking the value that is returned when
+the ports are open to the air. This value should be 0. If it is not, you can use the offset option to correct the
+reading. For example, if your sensor is reading -40Pa when the ports are disconnected, you can set the offset to 40.

+    # Example configuration entry
+    # It uses a filter offset to calibrate the sensor
+    sensor:
+      - platform: xgzp68xx
+        temperature:
+            name: "Temperature"
+        pressure:
+            name: "Differential Pressure"
+            filters:
+                - offset: 40.5
+
+Configuration variables:
+------------------------
+
+- **temperature** (*Optional*): All options from :ref:`Sensor <config-sensor>`.
+- **pressure** (*Optional*): All options from :ref:`Sensor <config-sensor>`.
+- **k_value** (*Optional*, int): The K value comes from the datasheet. It will default to 4096 if not specified, which is appropriate for a sensor with a range of +/- 0.5kPa.
+- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the sensor. Defaults to ``60s``.
