I've purchased the Harmony 1100 and the RF Extender, I also have a complete X10 lights controlling system at home but, until now, I've not been able to control X10 with the Harmony 1100.
After some reading, it seems that I need an IR receiver that will "inject" the commands by powerline, like the IR-543, is that right ?
Do I really need to buy this interface to make my Harmony 1100 work with my X10 modules ?
Is there any other way to make them work together ?
Thanks for your help.

Hi and welcome to the forum .
Like all Harmonys the 1100 is for controlling devices that have original remotes that work by InfraRed.
In some cases it is possible to convert other devices to IR control so you could check on that for yours,

Thanks for your answer but in my case, my X10 devices can't directly receive IR commands, they only can receive RF commands, that's why I asked if I really must purchase an IR-543, just to be sure before buying it...

Yes. You must use the IR-543. It receives commands from an IR remote and sends them over your power lines to your X10/Lutron devices. If all your lights are on the same phase, you should have no problems. Otherwise you may need to install a phase coupling capacitor in your electrical box. Also keep in mind the IR-543 can only control one house code. If you have multiple house codes (more than 16 devices), you'll need the IR-543AH which is very expensive and very hard to find.
The IR-543 is only $13 shipped on ebay. There is no other way to interface an IR remote with an X10 system besides expensive Lutron bridge devices.
