ADT SmartThings door and window detector not available info

Just putting this out there for others that might run into this.

When we came home yesterday and disarmed the alarm, I noted one of my ADT Door and Window Detectors had gone offline.

Now it needs to be noted this one particular detector is using a secondary magnet, one pulled from an old Iris V1 door and window sensor, as it covers a window that has a window unit AC in it…

After a quick review of the issues I found online, I simply opened the window all the way to break the magnetic field, and then reclosed it, and the sensor became avaialble again, and showed itself closed…

Long story short, if you have a door and window detector that goes unavailable, try opening / closing it. At least that is what worked with mine…
