Historically my wife has filled our house with different brands of 433MHz switches. When I bought my Vera two months ago I realized that it will be too expensive to replace all those old switches with new nice Z-wave switches so then I started with MySensors stuff to create a actuator for controlling all this old stuff.
Since it is a lot of different brands (no Nexa stuff) I couldn't get them to work with those samples library that you can find around. Instead I have to build my RF listener and try to decode the signal. I can't find the link right now to the listener but you connect a 433MHz receiver to the mic input on your computer and then use the Audacity program to record the signal.
Then I created a lib and a sketch for my different switches and it worked on my breadboard. So finally I packed everything, a gateway and my 433MHz actuator, in a box.
It works fine, and the WAF is for the moment on top.
One problem is that that the gateway and Ethernet module sometimes just stops and need a restart, I will investigate this further on when I got some time.

And a sample sketch
Now it is mounted in the "engine" room, "branded" and all. On the left is the Vera, notice that I had to mount the Vera with a string because Micasa Verde has "forgot" to make wallmounting holes in the box!! (that is not the only thing they forgot on the Vera Edge..)
