Convert sound signal to dry contact signal? Answered
This might be a bit of a strange question, so will try and word it so someone can follow along.
I posted a thread previous about getting my doorbell chime to work with SmartThings. What I now have is a sensor with external input. The keep it simple, there inputs are GRND and IN. When the 2 inputs are joined, the device reads CLOSED and when they are apart, the device reads OPEN...perfect.
I've been trying to find a point on my Chimes circuit board that would create a dry contact between 2 points to trigger the sensor, but I'm not having a great deal of joy.
There are however, 2 wires running from the board to a speaker in the unit. Is there anyway I can get convert the signal to the speakers into a signal which would connect the 2 wires?
I know a speaker is an electromagnet that responds to electric signals, but wasn't sure if there was something preventing the contact being made between the 2 sensor wires
