  • a radio frequency (RF) radio configured to directly communicate with a routing device over a plurality of channels, wherein the remote device and the routing device are associated with a network, and wherein the RF radio does not send or receive messages during the sleep mode;

    memory configured to store a unique identifier associated with the remote device and a network identifier associated with the network;

    a processing element configured to initiate the awake mode on a periodic basis, monitor one or more channels of the plurality of channels during the awake mode, determine an energy level associated with each monitored channel, and determine whether a message is being received based on the monitored energy levels, wherein the processing element is further configured to determine whether to process the received message based on one or more identifiers provided in the received message, the unique identifier, and the network identifier, and wherein the processing element is configured to generate a responsive message based on the processed received message;

    an apparatus; and

    a sensor, wherein the sensor and the apparatus are configured to operate during the sleep mode and the awake mode, wherein the processing element is configured, during the sleep mode and the awake mode, to receive data from the sensor and generate the responsive message based on the received sensor data, and provide the responsive message to the RF radio, and wherein the RF radio is configured to the transmit the responsive message to the routing device during the awake mode.
