Thanks! Appreciate your help !I believe the current wiring design is heavily based on my initial writeup. I've been in contact with COZero and giving them suggestions on making it a more complete kit. Like you have noticed the placement for the controller is near the power tap, also the ground wire is near there too. Please check out the pictures from my post a few pages back on the placements I made.

Not sure why the fob would open but not close though. Have you reached out to COZero? They have been pretty responsive in my experience.
