I couldn't find any way to actually find out what the device itself
is/who's the manufacturer...the page had so much ad copy never loaded
fully and the link to "purchase list" or whatever it was actually called
just self-directed to the same page.

You got the product info; what kind of range does the switch have; only
a few feet? I've kept eyes out for long-range switch for barn light
from house w/o having to wire it but it's 100 yds or thereabouts away...

The wired and wireless X-10 light switches and outlets will work if
the barn and the house outlet the wired X-10 wireless receiverr is
plugged into are on the same side of the split 220. The x-10 signals
over the house wiring and doesn't always make it to the "other side".
Yes, it's ancient technology - but it works. I have a houseful,
including a programmable timer (programmed from a PC) that can have
different lighting patterns every day for a year..

X10 either works well or doesn't work at all. It's not just
transformers that stop it (the two 120V legs can be tied together with
a capacitor - X10 makes approved widgets for this purpose). Noise
will also kill the X10 signal. If it works in your house, it's great
stuff (for a 40 YO technology) but it often just doesn't.
