Wyze Sense cylindrical recessed bracket is designed to be easy to install if you want to recess the sensor into a door/jam. It is designed with simplicity of installation in mind. After getting everything connected place the wyze sensor in the bracket so that the wyze logo is closest to the round front plate. you will need to use a 1" paddle bit to drill in about 1/16th of an inch. Then use a 7/8" bit to drill 1-1/2" to 2" the bracket should slide nicely in and sit flush. If it is loose putting a little electrical tape around it should to do the trick.
The magnet can be placed in another bracket of the same design. The only difference is the inner hole you need to drill is about 5/8" again if that is too big some tape will probably work.
I have added small holes in the face so allow the bracket to be hooked and pulled out of the wall easily.
