  • a power receptacle;

    a power plug;

    a current sensor configured to read current drawn through the power receptacle; and

    a controller configured to execute a program, the program comprising;

    logic that generates power profile data indicating a plurality of automatically detected current draw periods, the power profile data being generated based at least in part on monitoring current draw with the current sensor when a learning mode is active;

    logic that determines that one of the automatically detected current draw periods is active based at least in part on the power profile data;

    logic that determines that a current draw reading is abnormal when the current draw reading meets a threshold associated with the one of the automatically detected current draw periods that is active; and

    logic that performs an action when the current draw reading is determined to be abnormal.
