    This thread is to describe how I am controlling my doorbell utilizing a Raspberry Pi and relay board. I am basically opening the 24V AC connection in the doorbell circuit to disable the doorbell during defined intervals in the Home Intelligence Management System. I used a 2 channel sainsmart relay board. Someone already put together a great diagram of using the Sainsmart relay boards found here.

    Here’s a picture of how this could be wired when using GPIO port number 25.
