1. A system to determine a state of a door of a building, the system comprising:

  • a door state detector configured to detect whether a state of a door associated with an entry to a building is one of a locked state and an unlocked state;

    a hub device in communication with a mesh network and configured to transmit through the mesh network a door command to control locking and unlocking of the door, the mesh network configured to propagate the door command using powerline signaling and radio frequency (RF) signaling, the door command being one of a lock command and an unlock command;

    a receiver configured to wirelessly detect a presence of a first RF signal having a first frequency, the presence of the first RF signal indicative of the door command encoded onto the powerline, the receiver further configured to wake up from an inactive state based on the presence of the first RF signal on the powerline to receive the door command via a second RF signal having a second frequency different from the first frequency; and

    a door lock controller in communication with the receiver and operably connected to an electronic door lock associated with the door, the electronic door lock configured to automatically move between a first locked position and a second unlocked position based on the door command, the door lock controller further in communication with the door state detector and configured to transmit after receiving the door command the door state to the receiver for propagation through the mesh network to the hub device, the hub device further configured to compare the door state with the door command and to transmit an alert to a user when the door command is the lock command and the door state is the unlocked state.
