I posted a set of findings here [I think]
and on
www.accessha.com.
X10 OEMed the Freewire stuff for B&D. The
FCC ID on the remotes go back to X10. X10
and Frewire modules are interchangable. An
X10 controller can control a Freewire Module
and a Freewire Crontroller can control an
X10 module. I have programed the weather
resistant Freewire module with an X10
controller. The Remotes and Tranceivers are
NOT interchangeable. Different Frequencies
of the RF signals. X10 310Mhz Freewire
418Mhz.
