@Beeblebrox666 you can use them just like any other strip, with the limitation that not all leds can be controlled individually.

@yoshida I'm not sure... Maybe

@yoshida hi! Im not sure where you get that #9 should be A5? Looks right to me. The pin is connected to pin 9, and that is D3. For a rotary encoder, it depends on your input - but don't you want an analog signal in? In that case you use the analog pins. Edit: offcourse, if you use a module converting it to digital like described in the the build section you use a digital pin.

Hi and welcome to the MySensors community @augusthalverson ! In general, you just set the color in your controller. It works the same way regardless of which type of gateway you are using, so there is nothing specific about mqtt. You might be able to get some inspiration from https://forum.mysensors.org/topic/4934/wall-mounted-mood-light-v2
