just after your [metro] (i assume you have one), insert a [t b b b]. With
the right outlet, send a 1 to turn on a [spigot]. With the middle outlet
of t, connect to your stuff that should produce a message or not. Use that
to send a 0 to turn off the spigot. Then with the left outlet of t, send a
bang in the spigot and see whether it goes through. It will go through
only when nothing was received to turn off the [spigot].
for other occasions, you can swap some outlets of the [t b b b], or
replace the [metro] by something else...
