You could also just use moses, either two times or just ignore the
upper bound, because most midi cc messages don't go above that.

Then there is [change] and [delay] wich both are build-in.

What happens, if sensor 1 was inactive in the previous go???

Here I could advertise ">" or "<" or hierarchical "route" objects.

I attached an example. It converts your 8 possible states to a number,
that is only output if your either bang (after for example a minute),
or if it changes. 

You could do whatever you want with that number, it is unique for
every state possible. 

I did not account for your last problem yet, because of my open
question. Depending on the answer, you would do something with the
toggle-state of sensor 1 like send it to a spigot.

ciao
