เพื่อที่จะส่งข้อความเข้า Application จึงจำเป็นต้องแปลงข้อความอีกครั้ง โดยใช้โหนด Switch (ตอนนี้ตั้งชื่อว่า Message Handler) เพื่อแปลงจากสัญญาณ 1 = เปิด, 0 = ปิด ให้เป็นข้อความที่เข้าใจได้ง่าย จากนั้นส่งไปที่โหนด Push ซึ่งอยู่ในกลุ่มของ NETPIE ในหน้าแถบด้านซ้าย

โดยการตั้งค่าของทั้งสองโหนด เป็นไปดังต่อไปนี้
