Dom,
Have you considered this smart outlet from Samsung?

It will NOT deal with the variable speed. However you can turn it on/off. Just put the current switch into a small box and then run the house size to a standard plug. Replace a wall outlet with the smart outlet (you could replace at the old switch location but it is likely up on the wall and highly visible).
What you really want is something like a smart dimmer switch but one that works as the voltages you require. Here are some ideas from the smart home web site.

As long as your house controller supports the standard (call smart home) then your phone can control them. But call to make sure.
Note that I do not buy from these guys. I ask them all my questions and then buy through Best Buy because I can return opened packages to Best Buy if it doesn't work.
Best of luck, my friend. I'm anxious to see what advice you get.
