With the advent of home automation and the Internet of Things (IoT), we have become reliant on a variety of devices that require remote controls. But keeping track of an ever-expanding assortment of remotes can quickly become a daunting task. Do not fret, for we have arrived with the ultimate remedy to streamline your home automation experience: behold, the cloning remote. This ingenious tool can duplicate up to four remote functions and is set to revolutionize the way you control your devices.

In this article, we explore the fascinating world of cloning remotes, where convenience seamlessly blends with efficiency. We delve into the remarkable technology that enables you to consolidate multiple remotes into a single, compact device, ultimately simplifying your life and enriching your home automation experience.

  • Connect the AC power supply to the Input Pins of the SMPS Module.
  • Connect one wire of the Bulb Holder to the AC input and the other to the COM port of the relay.
  • Connect the NO port of the relay to one of the AC inputs pins.
  • Connect the DC Output pins of the SMPS module to the +V and -V pins of the relay module.

You can refer to our blog on Home Automation using RF Remote for learning about the RF Remote, RF Receiver and SMPS Module in detail. The blog follows the same circuit, so you can also understand the SMPS module connections from the same.


433 MHz Cloning Remote

433 MHz Cloning Remote

The 433 MHz cloning clone copy code RF remote control duplicator offers an ingenious solution for individuals seeking to simplify their collection of remote controls or replace those that have been misplaced or harmed. With the ability to replicate the codes of an existing 433 MHz RF remote control, this device proves to be a valuable convenience.

It has a range of around 100m and requires a 3V battery as its power source. 

The cloning remote is endowed with a mode of learning that enables it to capture and store the codes transmitted by the primary RF remote control.

Let us observe the functionality of the cloning remote.

Clearing Code from Clone

Within the Cloning remote lies the possibility of an existing code, one that has been replicated from a previous source. To see if there is an old code, you can press and hold a button on the remote. If the light blinks and turns off quickly, it means there is no code. But if the light blinks for as long as you hold the button, it means there is a code saved.

To eradicate this code, one must press buttons A and B until the LED begins to flash. Hold down the A button and press the B button three times, then release both buttons.

To check if the code has been erased, press, and keep holding any of the buttons. You will see that the light stops after blinking for a little while.

Copying the Code

To copy a button from the original remote to the clone remote, place them within 10mm of each other and press the desired button on the original remote. At the same time, press the corresponding button on the clone remote. Hold both buttons down until the LED on the clone remote flashes.

To make sure that the code has been copied correctly, press the same button that you copied. You will notice that the light keeps blinking until you let go of the button.

Congratulations, your original remote key functions have been successfully cloned.

Retrieving Previous Code

If you want to get back the code you used before, just hold down the C and D buttons until the LED starts flashing.


Working of the Home Automation System

Now that we have copied the code from the original remote, it is time to test the working of the clone remote.

Press the buttons that you have copied from the original remote and check if they carry out the same tasks. If the buttons are not functioning properly, attempt to replicate the code once more by repeating the procedure mentioned earlier.

If your devices are in Toggle Mode, you can store up to four clone functions from four different remotes. However, if your devices are in Latch Mode, you can only store two clone functions from two remotes. This way you can perform functions of multiple remotes using a single remote, which provides ease and comfort to the homeowners.



The cloning remote at 433 MHz has brought a revolution to the field of remote-control technology. Duplicating current remote codes simplifies the handling of numerous remotes and provides convenience and control in a single device. Embracing this innovative approach entails bidding farewell to the mess of remote controls and embracing a more organized and effective control solution.
