1. A door assembly comprising:
- a first door skin;
a second door skin spaced apart from the first door skin;
an energy sensor generating an energy signature signal;
a memory storing a door component operating signature;
a controller coupled to the energy sensor and forms a comparison of the energy signature signal to the door component operating signature and generates a door component operation status signal in response to the comparison.

Abstract
A door assembly includes a first door skin and a second door skin spaced apart from the first door skin. The assembly also includes an energy sensor generating an energy signature signal and a memory storing a door component operating signature. A controller is coupled to the accelerometer and forms a comparison of the energy signature signal to the door component operating signature and generates a door component operation status signal in response to the comparison.
