I don’t want to replace my locks with an electronic solution, but looking for a way to determine if a deadbolt is engaged or not. I have door sensors, but want to determine if doors are locked or not. Anyone have a good solution for this that doesn’t involve replacing the lock itself?
Some of the door sensors support an external reed switch. You could mount a reed switch in the bolt hole to tell if it is thrown.
Unfortunately your best option is the one you don’t want for some reason.
We have these silly expensive and almost undefeatable Mul-t-locks in our doors, and the cylinders can’t be used in electronic locks unfortunately. As much as I love technology, I’m still not sold on electronic locks just yet.
We have full metal steel cup steel boxes for the deadbolts, so the drilling in there isn’t an option. I know I have a lot of requirements, just hoping that there’s a solution that my Googling didn’t uncover.
I’m just surprised there isn’t any kind of solution to read the state of the deadbolt. Anyone want to get in on a Kickstarter with me (you’d need to come up with the design and capital, but I’d happily put my name on it). 
The Schlage 469 series of electronic deadbolts are rated as ANSI level 1 (most of the other electronic deadbolts are ANSI level 2).
Which means to me that the deadbolt will still be there after the bad guys have kicked the door open. Or entered via the window.
It’s been years but I used to install latch bolt monitors on doors to determine door poison and latch status. It has a little flap that is depressed latch bolt. It than gets wired to an input on whatever you use monitor it.

Where is this device? Have a link?
Here is an example of one: you will need to work out the correct way to hook it to a zwave sensor (like a Fibaro universal binary sensor and give it the 5 amps it needs)

That should work for the OP right there!
Also it doesn’t need 5amps it capable of handling 5 amps which is not needed for wiring to a door/window sensor.
With this kit and a z-wave door and window sensor both wires wired to each the OP should be good to go!
