This mod is very straightforward once the lamp is opened and the original control board is removed.
Wire the ESP32 to the lamp’s LED strip like this:
- Black -> GND
- White -> 5V
- Brown -> Data (GPIO 2)
Then open the WLED interface and set the following options:
- LED count:
30 - Color order:
GRB - LED type:
WS281x
After that, the lamp should light up correctly with WLED.
Go to your local IKEA store and pick up the lamp first.
Use a prying tool to carefully open the lamp body.
The lamp is lightly glued at the top and bottom, so do this slowly to avoid damaging the housing. Once the modification is complete, it should be glued back together again.
Remove the two side screws that hold the control board in place, then lift the board out.
Underneath, you will find the control board with the two buttons and the microphone. Unfortunately, the support bracket is glued in place, so removing it will require breaking it free by force.
If you want to keep the original button functions, the simplest way is to remove the original IC from the board and wire the two button pins directly to the ESP32.
Button 1 is on pin 3 and Button 2 is on pin 4.
Wire the buttons to the ESP32 like this:
- Button 1 / pin 3 -> GPIO 0
- Button 2 / pin 4 -> GPIO 1
I used an ESP32-C3 SuperMini.
I recommend placing it in the cavity opposite the one where the original control board was located, so it stays farther away from the heat generated by the LEDs.
Connect the wires as follows:
- Black to GND
- White to 5V
- Brown to GPIO 2 for data
In WLED, set:
- LED count:
30 - Color order:
GRB - LED type:
WS281x
Save the configuration and test a few colors to confirm everything is working.
If you connected the original buttons, also configure:
- Button 1:
GPIO 0 - Button 2:
GPIO 1
Put everything back together, close the lamp, and glue the shell again if needed.
At this point the lamp is ready to use with WLED.
The lamp now works as a smart WLED-controlled light, powered by an ESP32-C3 SuperMini and ready for custom effects, colors, and automation.
