Pi Zero W Freezer Alarm #piday #raspberrypi @Raspberry_Pi
From BillP48 on Instructables:
Our freezer is in a utility room which is isolated from our living space. Occasionally the freezer door doesn’t shut properly and the alarm goes off. The problem is that we can’t hear it if we are in our living space. How do we get a message that the freezer door is open?
