I get 5.1V out of the power regulator now
"Now"  So what about the voltage when you attempt to actuate the relays and it misbehaves?

5.14V when nothing connected and 5.12V with relays etc. connected.

I´m starting to think that could there be some faulty part here maybe? I doubt, cause still everything works when I use an external 5V for that one NodeMCU. This is so weird. I think I will try another power regulator for this. Just in case.
