metal door interfering with door way sensor/magnet

Question

I have a set of metal french doors that lead out to my back porch, I'm experiencing difficulty with sensor and magnet recognizing the door is closed, I receive a warning every time I turn on my system, telling me that my back door is open, I have added additional thickness between the door and sensor with additional adhesive pads, in order  remove interference from the metal door, but still receive the warning that the door is open.

I don't think the metal doors is the problem, I have them on three metal doors and they have worked well for three years now. It sounds like the space between the magnet and sensor is too much.

They should work fine on metal doors, we have them on 5 of them.  Sensor on door, magnet on frame.  Unless your frame is metal also? If that's the case you're going to have some issues.

Sensor and magnet should be no more than 2 inches apart...ideally, they should be about an inch or less if possible.  As DP mentions about metal doors, maybe reverse the sensor and magnet (sensor on door/magnet on frame, or vice versa).  Also make sure that with the padding you are using, that both the sensor and the magnet are flush together in depth, or it will sometimes cause that 'door open' message.

You might try turning the magnet piece sideways(one 'end' toward the sensor)...because technically speaking, when metal interferes with magnets the magnetic field shifts or 'rotates' enough for the sensor to not recognize that side of the magnet)
