I want to attach a device that can send a signal over wireless to my server when the door bell is pressed. I'm assuming the device would tap into the wiring for the door bell, so that when pressed, the voltage triggers the relay on the wifi device to send the signal. Does anyone know of a device that can do this or lead me to a guide on how to create such a thing?
This is the start of my home automation project. I have looked at many "off-the-shelf" products and there has yet to be anything that can be a complete system with the devices I have or want to buy. A lot of it is "you need to buy this for that to work".
