I have tried plugging in my PLA5456 units into various outlets, but I cannot get the home light to light up.

Hi, 

Do you try to reset them?
After reset, they will have the same group key, and you are able to see the Homeplug LED light and it means the 2 PLAs are connected.
Moreover, you can press encrypt button within 0.5~2.5 sec, then the 2 PLAs will pair to each other, and you are able to use them in your network.
