Going the X10 route you'll need to pick up an IR543 and some X10 compatible wall switches, dimmers, lamp modules, etc. The IR543 is used to receive IR signals from your TSU7000, then sending them on as X10 signals through the electrical wiring in your home to any X10 devices you may have. I have an IR543 and a couple lamp modules myself which I use in conjunction with my Pronto. Works very well. If interested, feel free to download my TSU7500 PCF via the link in my signature area below. It contains all the IR codes for the IR543, including this device. If you're just interested in the IR codes they can be found all together on one page under the Pronto Signals section of my PCF.
