- Sun Oct 22, 2017 6:15 am #71069 I've been reading various posts about using mains AC for the ESP but they all seem to use separate power supplies for the ESP and the other device e.g. a lightbulb.

What I was hoping to do is have one power supply with a module that can then power the ESP and the relay / lightbulb.

I've drawn a picture of what I am roughly hoping to achieve.

Is this possible and does such a thing exist or am I living in fantasy land?

I've done projects before with mains AC but I'll always take advice to be careful and learn from those more knowledgable than me.
