Wled: Possibility to control several relays

[autonomobil]

Is there a possibility to control a 4-channel relay module, for example with pin D5-D8?

If yes where should I start to implement it?

[bogeuh]

pick a method of control
control the relay with chosen method
then you will know what to add where
work bottom up instead of top down

Even I modified for Alexa & mqtt control. It was modified within other scripts. I want to move the lines in usermod so when there is a version update, it will be easy to just copy the usermod.ino
