This is effectively the same as the light switch but is generalized to enable power on an outlet.

The ESP board should be powered via the mains, so I need a buck converter of some kind, probably like this simple circuit that takes 110v down to 12v and then to 5v or lower.

It would seem that the easy way to do this is to use a 433MHz socket along with the Pi and the rc-switch library. rc-switch provides some sample projects that might provide templates for creating Ironman interfaces.
