A device network includes an Internet-of-things (IoT) device, a gateway device, a communication device, and a monitor system. The monitor system establishes a first communication path to the IoT device via the gateway device, determines that the gateway device has failed and that the first communication path has been interrupted, determines that the communication device is within communications range of the IoT device, and directs the communication device to establish a second communication path between the IoT device and the monitor system via the communication device in response to determining that the communication device is within communications range of the IoT device.
