1. A battery-powered door lock control system operating remotely from a powerline and configured to interface with a mesh network, the system comprising:

  • a door lock controller configured to receive a door lock command, the door lock controller operably connected to a door lock associated with an entry to a building to automatically move the door lock between a first locked position and a second unlocked position based at least in part on the door lock command, wherein the door lock controller is electrically disconnected from a powerline;

    a local receiver configured to wirelessly detect a presence of a first radio frequency (RF) signal having a first frequency, the presence of the first RF signal indicative of a first message encoded onto the powerline, wherein the local receiver is electrically disconnected from the powerline; and

    the local receiver further configured to wake up from an inactive state upon receipt of the presence of the first RF signal on the powerline to receive a second message via a second RF signal having a second RF frequency different from the first RF frequency and to determine whether a device address of the second message is an assigned address, the local receiver returning to an inactive state when the device address of the second message is not the assigned address, the second message comprising the door lock command when the device address is the assigned address, the local receiver sending the door lock command to the door lock controller.
