Here's my situation:
I currently have 3 lights in the bedroom: 2 nightstand and 1floorlamp. I want to retain individual control of each lamp. I currently have a few of the wireless light switches with 3 buttons - they work well enough.
However, I want 1 master switch by the door that turns all 3 of the modules on and off with one button. I don't want to have to press multiple buttons. It seems like the most logical way to do this is to somehow configure the 3 appliance modules to ALSO respond to an additional unit or house code, sent by the master switch.
Any ideas how to accomplish this? I'm open to other alternatives.
To give you a bit of perhaps unnecessary detail: The "master switch" is a pre-existing switch that controls a switched outlet. I can get it to send x-10 signals by hooking up a powerflash module to the outlet, which is what I've been doing in other rooms and it works great. This is a rental, so I don't want to pull the switch itself to replace it with the x-10 variety. So, I need a solution that works with the powerflash interface, if that makes any difference. If you're not familiar with the powerflash modules, they just send a specified x10 code when they're triggered, same as any other switch.
