IKEA TRÅDFRI LED Power Supply: A Cheap and Hackable ZigBee Device



Hacking The IKEA TRADFRI LED Power Supply: How to Create Your Own Custom Smart Lighting Solutions




Smart lighting is one of the most popular and accessible ways to make your home smarter and more comfortable. With smart lighting, you can adjust the brightness, color, and temperature of your lights with your smartphone, voice assistant, or remote control. You can also create scenes, schedules, and automations to suit your mood and needs.




Hacking The IKEA TRADFRI LED Power Supply



However, smart lighting products can also be expensive, limited, and proprietary. If you want to use your own LED products, or if you want to have more control and flexibility over your smart lighting network, you might be disappointed by the options available on the market.


That's why some smart lighting enthusiasts have decided to hack The IKEA TRADFRI LED Power Supply , a device that powers and controls IKEA's smart lighting products. By hacking this device, you can use it to power and control any LED product that you want. You can also modify its firmware to change its settings or add new features. You can even connect it to your own network or software and control it with your smartphone, voice assistant, or computer.


What is The IKEA TRADFRI LED Power Supply?




The IKEA TRADFRI LED Power Supply is a small circuit board that comes with IKEA's smart lighting products, such as LED lamps and panels. It has two main functions: to convert AC power to DC power for the LEDs, and to communicate with other TRADFRI devices and hubs using ZigBee Light Link protocol.


The IKEA TRADFRI LED Power Supply contains a TRADFRI module, which is the brain of the device. The TRADFRI module is a small square chip that has a microcontroller and a ZigBee radio. It also has some GPIO pins that are used to control the LED driver. The TRADFRI module is used in many of IKEA's smart lighting products, and it is actually removable and replaceable.


Why Hack The IKEA TRADFRI LED Power Supply?




There are many reasons why you might want to hack The IKEA TRADFRI LED Power Supply . Here are some of them:


  • You want to use it for your own LED products that are not compatible with IKEA's products.



  • You want to control it with your own network or software, such as MQTT, Home Assistant, or MicroPython.



  • You want to flash it with your own firmware, to change its behavior or add new features.



  • You want to learn more about electronics and programming, and have some fun hacking.



Hacking The IKEA TRADFRI LED Power Supply can give you more flexibility and creativity over your smart lighting. It can also save you some money, as you can use cheaper or recycled LED products instead of buying new ones from IKEA.


How to Hack The IKEA TRADFRI LED Power Supply?




To hack The IKEA TRADFRI LED Power Supply , you will need some tools and materials, such as:


  • An IKEA TRADFRI LED power supply (either 10W or 30W)



  • A soldering iron and some wires



  • A SWD programmer (such as ST-Link or J-Link)



  • Some software tools (such as OpenOCD, Simplicity Studio, or MicroPython)



You will also need some basic knowledge of electronics and programming. If you are not familiar with these topics, you might want to do some research before attempting this hack.


The hacking process involves four main steps:


  • Opening up The IKEA TRADFRI LED Power Supply and locating the circuit board.



  • Connecting the SWD programmer to the TRADFRI module.



  • Reading and writing the flash memory of the module.



  • Using or modifying the module for your own purposes.



We will explain each step in more detail below.


Step 1: Opening up The IKEA TRADFRI LED Power Supply




The first step is to open up The IKEA TRADFRI LED Power Supply and locate the circuit board. Depending on the model, you might have to unscrew or pry open the plastic case. Be careful not to damage any components or wires inside.


Once you have access to the circuit board, you will see the TRADFRI module. This is a small square chip that contains a microcontroller and a ZigBee radio. It also has some GPIO pins that are used to control the LED driver. You can find more details and pictures of the module in this GitHub repository.


Step 2: Connecting the SWD Programmer to the TRADFRI Module




The next step is to connect the SWD programmer to the module. The SWD pins are usually exposed on the board, but sometimes they are covered by a sticker or a blob of glue. You can use a multimeter or a continuity tester to find them. Alternatively, you can refer to this resource page for hacking The IKEA TRADFRI LED Power Supply , which has schematic diagrams and pinouts for different models.


After connecting the SWD programmer, you can use OpenOCD or Simplicity Studio to read and write the flash memory of the module. You can also use MicroPython to run Python code on the module. This allows you to control the GPIO pins and communicate with other devices via serial or ZigBee.


Step 3: Reading and Writing the Flash Memory of the Module




The third step is to read and write the flash memory of the module. This is where you can backup or modify the firmware of the device. The firmware is the software that runs on the microcontroller and controls its behavior.


To read and write the flash memory, you will need some software tools such as OpenOCD or Simplicity Studio. These tools can communicate with the SWD programmer and access the memory of the module. You can find more details on how to use these tools in this Hackaday article or this Instructables project.


You can also use MicroPython to run Python code on the module without writing it to flash memory. MicroPython is a version of Python that runs on microcontrollers. It allows you to interact with hardware using simple commands. You can find more details on how to use MicroPython on this resource page.


Step 4: Using or Modifying The Module for Your Own Purposes




The final step is to use or modify The Module for your own purposes. This is where you can unleash your creativity and imagination. You can use it for various DIY smart lighting projects, or modify its firmware to add new features or improve its performance.


Here are some examples of what other hackers have done with their hacked IKEA TRADFRI LED power supplies:


  • Load The Silicon Labs EmberZNet ZigBee coordinator firmware on The Module and use it to set up your own ZigBee network.



  • Modify The Firmware to change The Minimum brightness level or add other features.



  • Connect it to your own LED strip or panel and control it with your smartphone or voice assistant.



  • Use it as a PWM dimmer for any 12V or 24V LED load.



  • Install MicroPython on it and run your own scripts or applications.



Conclusion




Hacking The IKEA TRADFRI LED Power Supply is a fun and rewarding project that can give you more control and flexibility over your smart lighting. It is also a great way
