Yes. Both send a signal back about it (I can see the Z-Wave dongle on my Almond 3 flash) but right now Securifi cannot report it. Maybe we will see that in the future. I asked at any rate.
I have tried them with reed switches, push button switches, and bare wires... They seem to be fine with whatever means to open or close the circuit. I guess someone could use it with a completely separate circuit even.
A related workaround would be to just wire leads to the original reed switch itself (or on other models where it is accessible).That way you could completely customize the trigger and it would be possible with almost all door/window sensors someone might get hold of.
I am looking at maybe using some connected to aquarium float switches for "wireless" monitoring.
