I have similar questions. I'm building the door itself from scratch but
would like a commercial solution that controls direction from which the
pet-collar will cause door to open.

This is the most likely commercial candidate to hack I've seen so far,
but oh so very ugly! And I've no idea what it might take to make
externally controllable although it ma simply require SPST switches
across the contacts of the existing push buttons (assuming they aren't
capacitive or membrane.
