Hi,
Wow, that's great that he is on-board with your interest in feng shui!
Let's see, to the best of your ability, with the door open take your reading standing inside the center of the door frame, facing outside your home with the compass at heart level. Take the reading from where the frame now stands. Any metal will affect the reading so try to get the reading as free of metal as possible. You may have to take a few readings to get a sense of the magnetic directions and therefore how the energy is moving as it enters your home.
If your front door falls on a temple or empty line you may want to use a hexagram to shift the degree either 5 degree increments down or up (ex: 95 or 85, with degrees in between)
All the best!
