what exactly do you want to happen when you say "Computer.... View screen ON"?
I sorry Bill. I don't what I am thinking tonight. Actually, what I would like to happen is: appliance module D9 to turn ON
OK, then the answer is yes!
If you create a device named "View screen" with the address D9 and selecting the appropriate output mode (power line command, RF or both), then saying "View screen on" would issue D9 ON through the CM15A.
Obviously "View screen off" would issue the D9 OFF command.
You could also say "Computer, activate view screen" and "Computer, de-activate view screen" (if you want to get really Trekkie
)
P.S.
This all assumes that you set up AHP or an appropriate MACRO in AHP so that when D9 ON is triggered the appropriate X10 commands are sent. The switching of X10 cameras requires that you send OFF commands to all of the cameras and then send ON to the camera you want to view. AHP can do this if set up correctly, but BXVC (so far) only sends one command (i.e. D9 ON) so something else (AHP) must send the appropriate off commmands.
I'm working on adding MACRO sequences to BXVC so that it could send that "string" of commands directly, but I've got some work to do yet.
