+
+## Binary Sensor
+
+The `pi4ioe5v9xxxx` binary sensor platform allows you to read sensor values from the I/O pins of your I/O expander.
+
+The pin numbers are from 1 to X where: 1-8 correspond to port 0 (00-07) and 9-16 to port 1, etc.
+
+### Configuration
+
+To use the I/O pins of an pi4ioe5v9xxxx connected to an I2C bus of your Raspberry Pi as binary sensors, add the following to your `configuration.yaml` file:
+
+```yaml
+# Example configuration.yaml entry
+binary_sensor:
+- platform: pi4ioe5v9xxxx
+  pins:
+    1: Pin_01/PI0_0
+    2: Pin_02/PI0_1
+    3: Pin_03/PI0_2
+    4: Pin_04/PI0_3
+    5: Pin_05/PI0_4
+    6: Pin_06/PI0_5
+    7: Pin_07/PI0_6
+    8: Pin_08/PI0_7
+```
+
+{% configuration %}

+  keys:
+    "pin: name":
+      description: The pin numbers (from 1 to X) and corresponding names.
+      required: true

+bits:
+  description: number of bits of pi4ioe5v9xxxx chip, see particular datasheet for your device for the right number.
+  required: false
+  type: integer

+  required: false
+  type: boolean
+  default: "`false` (ACTIVE HIGH)"
+{% endconfiguration %}
+
+
+## Switch
+
+The `pi4ioe5v9xxxx` switch platform allows you to write to the I/O pins of your I2C I/O expander.
+
+The pin numbers are from 1 to X, where 1-8 correspond to port A (A1-A8) and 9-16 to port B (B1-B8), etc.
+
+### Configuration
+
+To use the I/O pins of an pi4ioe5v9xxxx connected to an I2C bus as switches, add the following to your `configuration.yaml` file:
+
+```yaml
+# Example configuration.yaml entry
+switch:
+  - platform: pi4ioe5v9xxxx
+    pins:
+     1: Pin_01/PI0_0
+     2: Pin_02/PI0_1
+     3: Pin_03/PI0_2
+     4: Pin_04/PI0_3
+     5: Pin_05/PI0_4
+     6: Pin_06/PI0_5
+     7: Pin_07/PI0_6
+     8: Pin_08/PI0_7
+```
