However, for users looking for standard numeric codes to program this device into a different universal remote (like a Logitech Harmony or a cable box remote), we will cover those possibilities as well.
If you have lost your original ZH JT-03 and have a new one, but the receiver has no "Learn" button, you need a (e.g., KeyDIY KD-900 or similar copier).
Connect an RF 433MHz receiver to an Arduino digital pin 2, upload the RCSwitch example sketch ("ReceiveDemo_Simple"), and press the ZH JT-03 button. The serial monitor will print the decimal and binary code. That is your definitive zh jt-03 remote control code .
