1. A method for calibrating a sensor to be configured to detect power states of a smart television, wherein the sensor is connected between the smart television and a power source, the method comprising:
monitoring, from the sensor, first current data of the smart television over a first time period during which the smart television is in a powered-off state;
monitoring, from the sensor, second current data of the smart television over a second time period during which the smart television is in a powered-on state and in a first input mode;
monitoring, from the sensor, third current data of the smart television over a third time period during which the smart television is in the powered-on state and in a second input mode, wherein power drawn by the smart television in the powered-on state and the second input mode is different from power drawn by the smart television in the powered-on state and the first input mode; and
calibrating the sensor based on the first current data of the smart television over the first time period, the second current data of the smart television over the second time period, and the third current data of the smart television over the third time period.
