I think I am OK now with the magnet placement.
Thanks for the reply. Yes, I saw both of these documents and that was how I placed the magnets. I figured that there was no way they would touch but just needed to be in close proximity to each other.
The magnet are meant to be attached to the dome part .
Did you look at the doc :
The magnet and sensor pass each other (which trigger the sensor)... they don't touch.
