I finally opened up my 4gang dumb light switch and see that I have neutral wires available (I assume they are the white ones)..
Unfortunately, I don't really understand how all these are put together...
Looking to install something like this (but open to anything that I can use to dim and switch on/off):

(2x) - I haven't ordered it yet,I want to first understand how complex the installation will be
Can someone suggest a video or info on how to wire all this up ? Should I just call an electrician ? I have experience with mains (built 3 3d printers), but I never tried to figure stuff out myself from scratch, as I feel like this is the case here. I don't even get the wiring diagram on the dimmer module.
