I've gotten  back to work on this project after a long absence.  Finally got tired of people knocking on my door instead of using the doorbell.  Worked through some kinks in the original design, updated and streamlined some of my circuit designs, and removed some superfluous components.  Finally sent out for a prototype board to OSHPark today to see if this design will work better than my previous attempt.  I've uploaded my KiCAD files if anyone else want to take a look or critique.
