That sounds really great. I think I'll try that, I even have all the parts!!
I wanted to be able to sense all seven states, and I didn't really want to use a
non-purist solution, so this system is perfect.
Now if someone could design a lamp-light sensor version, that would be even
better still, no moving parts.
