1. A communications device for providing data related to a power line, comprising:

  • a memory storing a scheduling table;

    a controller communicatively coupled to said memory;

    a first modem in communication with said controller;

    one or more sensors in communication with said controller;

    wherein a first sensor of said one or more sensors comprises a voltage sensor configured to measure a voltage of the power line;

    wherein said scheduling table comprises timing data indicating the timing of measurements to be taken by said voltage sensor;

    wherein said controller is configured to receive sensor data from said one or more sensors;

    wherein at least some of the sensor data comprises voltage data;

    wherein said controller is configured compare received voltage data with a threshold value;

    wherein said controller is configured to cause said first modem to transmit an alert notification if the voltage data is beyond the threshold value;

    wherein said controller is configured to cause said modem to transmit a recovery notification if, after the voltage data is determined to be beyond the threshold value, the voltage data is determined to be not beyond the threshold value; and

    wherein said controller is configured to cause said first modem to transmit at least some of said sensor data to a remote device.
