I've purchased perhaps a dozen (maybe more) wireless 12 volt controls and by virtue of the draw, no two were the same. China. Go figure.
For standard wireless controls, your issue is going to the the physical size of the remote. All had a heatshrink tipped antenna wire (usually colored blue).
Chop a pack of cigarettes in half and this will be roughly the size of a standard remote receiver and relay unit. The power will have to be switched so a standard porch light hole will have to be enlarged. Stuff the control into the hole after butt terminal connecting the + and the -
With a round file, make a groove channel so the antenna wire can stick out. Glue the tip of the wire atop the porch light parallel to make it look neat. And seal up any potential water entry pathways.
If you go this route, I endorse purchasing a couple extra transmitter batteries most of mine used A27 12 volt alkaline. And lastly whichever way you go please post images of the project.
