ESP32 tutorial for hacking your IKEA Rodulf to support web API
Connect your ESP32 with relay module using this pinout
| ESP32 | Relay module |
|---|---|
| VIN | VCC |
| GND | GND |
| D26 | IN1 |
| D27 | IN2 |
You can always repurpose an old LAN cable for this step.
IKEA uses RJ45 as the controller connector. Since there are only UP and DOWN directions, they utilize only 3 out of the 8 cables. These cables are orange for down, white/blue for up, and brown for ground. Connecting orange and brown would make the table go down, while connecting white/blue and brown would make the table go up.
| RJ45 Cable | IKEA usage |
|---|---|
| Orange | Down |
| White/Blue | Up |
| Brown | GND |
