IIRC the smirf shows up as a bluetooth to serial device ... so on your windows side, you need to use the visual basic MSCOMM control (or similar for the lang. of your choice)
for the device side, you need something with a UART to receive and understand the serial signals.
personally, at $45-60 a pop for smirfs, I'd ask myself, is a remote controlled lamp an ideal application for such an expensive device? you might want to look at the **broken link removed** modules, which can be found various places for under $20 ... the application on the PC would be the same, all it needs to know is it's talking to a serial device.
