1. A device, comprising:

  • one or more memories;

    one or more processors, communicatively coupled to the one or more memories, to;

    detect occurrence of an event associated with the device,the event related to at least one of;

    a time related event,a movement related event, ora message related event;

    receive energy storage information and solar charging information,the energy storage information identifying a present charge state for an energy storage component,the solar charging information identifying an output current for a solar array, andthe energy storage information and the solar charging information being received based on the occurrence of the event;

    set a time value and a radio operation state based on the present charge state being greater than a charge threshold and the output current of the solar array being less than a solar threshold,the solar threshold corresponding to a particular percentage of a maximum output current of the solar array,the radio operation state being for a wireless interface of the device, andthe radio operation state for the wireless interface of the device being powered off when the present charge state is below the charge threshold;

    determine, based on the time value, to determine location information;

    determine the location information,the location information being first location information;

    determine, prior to determining the first location information, second location information;

    determine a distance between a first location corresponding to the first location information and a second location corresponding to the second location information;

    transmit, over the wireless interface, the first location information based on the radio operation state and the distance being greater than a threshold; and

    turn off at least one radio after transmitting the location information over the wireless interface; and

    one or more mounting tabs,the one or more mounting tabs being configured to mount the device at a position on an asset to increase exposure to sunlight.
