A door lock/unlock system for a building automatically controls locking and unlocking of a door. A door lock controller interfaces with an electronic door lock and receives messages including door lock commands from a local receiver. In turn, the local receiver interfaces with a hub device through a mesh network. The hub applies a rule set to make lock operation decisions, and sends messages comprising commands to operate the door lock through the mesh network to the local receiver. The local receiver decodes the messages and passes the commands to the door lock controller to automatically control the electronic door lock. A door state device checks the state of the door. When the checking mechanism indicates that the message was not received or the lock operation failed, the system alerts the user to take appropriate lock action.
