My situation is this.
I have version 1? contact sensor that I want to use on a package dropbox but due to distance (about 40ft) from bridge and the box is metal and the obstacle of a house wall it doesn’t stay connected.
I cannot move the bridge or the box. And I don’t want to reinvest buying the v2 sense products, want to use what I already have.
My idea (see attached diagram) is to run a 2 lead wire from the box, either using the sensor outside or inside, to the inside of the house, powered by a battery adapter pack (2 AA batteries). If outside I will need to put something on the inside to indicate that the door was opened. Like a little light switch or something.
After looking at my diagram, can anyone see anything that I missed? Is this a doable idea? Has anyone ever heard or done anything like this before?
All creative comments welcome.
