Link: Door bell relay for HAI system

Here’s my finished setup of a door bell relay for my HAI system at home. I hate door bells, and wish I could have more control over them. Now I can react to a door bell press in far better ways… beeps to the console, flashing lights, sound output from another device, the ability to turn off the front porch light when some asshole is ringing my door bell after 9pm… The options are endless.
