USER ID?
? Maybe a UNIT ID. As long as
your remotes are set up to send different
house and unit codes - just create a macro
to do the required action.
Remote "A" push button 1 turns on the hall
light. Remote "B" push button 1 turns on
the bathroom light. Remote "A" push button
2 turns off the hallway light. Remote "B"
Push button 2 turns the bathroom light off.
You decide what the required action does
based upon your button press "trigger" and
set it up. The only thing is that you can't
have the remotes addressed to the same
house/unit codes and get a different action
if the same button is pressed on each
remote.
