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.
Here’s a picture of the Home Intelligence Management System doorbell status page.
Here’s a picture of the page to edit the configuration for off durations.
