-## Binary Input Functions
-
- * The example implements two binary inputs:
- - HVAC Fan Status: Reports the current state of a fan
- - Security Zone Armed: Reports the armed state of a security zone
- * By clicking the button (BOOT) on this board, it will toggle both binary inputs and immediately send a report of their states to the network.
+## Binary Input/Output Functions
+
+ * The example implements three binary devices:
+ - **Binary Fan Device (Endpoint 1)**: 
+ - Binary Input: HVAC Fan Status - Reports the current state of a fan
+ - Binary Output: HVAC Fan - Controls the fan switch with callback function
+ - **Binary Zone Device (Endpoint 2)**:
+ - Binary Input: Security Zone Armed - Reports the armed state of a security zone
+ - **Binary Humidifier Device (Endpoint 3)**:
+ - Binary Output: HVAC Humidifier - Controls the humidifier switch with callback function
+ * By clicking the button (BOOT) on this board, it will toggle all binary inputs/outputs and immediately send a report of their states to the network.
  * Holding the button for more than 3 seconds will trigger a factory reset of the Zigbee device.
