yup, you can control it from a PC.

here is a link to the aqua Jr, it has the controller options for hardwire(DC8) or 10x control AquaController Jr

here is quote for part of it, it has the part numbers if you need them

For X10 control, the AquaController sends a digital signal to the control interface (part number IM513) which places a small RF signal onto the powerlines in your home. The control modules (typically part number CM466) receive this X10 signal over the power lines, and if the code matches the user settable address the module is turned on or off. Up to 12 control modules can be controlled with the AquaController Jr.
