Hmm... With an internet connected ring + a internet connected locker... it's quite doable and simple.

The deliver guy comes... push the ring... you answer it on your phone and unlocks the box from it.

No delivery guy I've ever seen is going to sit around and wait for you to unlock the device. I can't remember the last time a delivery person even bothered to ring the doorbell.
