FluxLED not working properly

I have 2 Wifi LED Controllers. The first one is THIS ONE and the second one is THIS ONE. The first one, I have had for a while, and it works perfectly and as expected. I bought the second one since that I assumed they are exactly the same, and it’s actually what is linked to in the documentation for the FluxLED component. I am only using RGB on both controllers, NOT RGBWW.

The second controller is the one I am having issues with. I can turn the LED on and off just fine, and I can also change the colors just fine. However, the problem is with the brightness. Whenever I adjust the brightness, the color always changes to white. The brightness slider works, but the color is just always white.

Another strange behavior is that when I look at the States page in the web interface, the values always just say rgb_color: 255,255,255 and brightness: 13.

I’m not sure what is different about this one, but does anyone know what I should do to troubleshoot? Here’s what I have in the config for both controllers:

light:
  - platform: flux_led
    devices: 
      192.168.45.51:
        name: Bed LED
        mode: "rgb"
        protocol: 'ledenet'
      192.168.45.102:
        name: Kids Room
        mode: "rgb"
        protocol: 'ledenet'

Does anyone have any ideas on how to fix this?

Have you tried it without the protocol?
