Wow, do you sometimes wonder who it is that replies to our messages. Anyway, I just did this. I used a series of XPDI3 from home automation on the net.

The series is, sets of double gang boxes one side is the rocker switch the other an outlet to plug in the low-voltage transformer 300w is what I used because I wanted to create outdoor themes.

Utilizing the powerhouse stick on wall switch RSS18 I can control my rocker switches with dimming of my transformers.

I used mostly 50w bulbs, but one strand has 20w bulbs

The lights are FANTASTIC. I have garden scenes, and with the trigger of motion detectors, I create events.

And of course, the switches are controlled by anything x10 including my pronto tsu6000.
