Occlusion Culling (Doors)

I am using occlusion culling in my game and have defined occlusion areas for each of my rooms. I have doors in my rooms with an attached script that opens the door when the player gets near the door. If I tag the door as occluder and occludee static and open the door, the next room isn't visible until the player walks in the next room. However, if I don't tag the door as anything and the player looks at the door, the next room becomes visible in the occluder window.

How can I make the room not visible when looking at the door, but when I open the door the next room is visible?

 

You can deactive the door and bake for occlusion culling, than activate the door.
