Can't receive any valid signals from my CW/WW remote

[McAroni]

Hi there,
I want to control my Arduino UNO with a connected nRF24L01 module via the CW/WW remote from my Milight bulbs - sooo in theory your project should make this possible, right?

I connected the nRF24L01 module (and tested it with another piece of code) to my UNO and changed two lines in MiLightRadio.cpp since I want to use the CW/WW:
Line 12: static const uint8_t CHANNELS[] = {4, 39, 74};
Line 42: retval = _pl1167.setSyncword(0x050A, 0x55AA);
These changes were recommended by this page, which is my starting point to your project: https://arduino-projects4u.com/milight-rf-control/

Sadly, this doesn't appear to work as intended.
The channel settings seem to be fine since I can receive something (_radio.available() in PL1167_nRF24::receive does trigger correctly) but then I can't see that the received information can be handled. I assume the syncWord is wrong?

In the end, the program starts and waits for incoming (readable) data and can't detect anything.

I know, this project does not look like to be your most recent one, but I feel like this problem actually isn't that big.
I would really appreciate any help on this!
