I don't currently have any AHP stuff in my house (though I used the original AH stuff in a previous house). I have a light controlled on a 3-way switch at my entry-way, and another light about 20' down the hall, on a separate circuit and controlled by a separate 2-way switch.
Basically, I'm wondering if I can combine the switches in such a way that the lights all behave as if they're on a single 3-way (4-way?) circuit. In other words, I'd like flipping the 3-way to control the hall light, and flipping the 2-way on the hall light to control the entry light. Does the AHP stuff accommodate this sort of arrangement if you match the house/unit code?
Also, do you need a software/control unit to make any use of the AHP system at all, or could I just go with the switches for something like this?
