Provided is a controller that enables reduction of processes required for changing a threshold value, which is used for determining a state of an electric device, in a case of occurrence of an operation mode change, exchange, degradation or the like of the electric device. The controller (12) comprises a comparison unit (125), a communication unit (126) and a setting unit (127). The comparison unit (125) determines whether the difference between a number of occurrences of operating states on a previous day and a number of occurrences of operating states on the day before the previous day is equal to or greater than a predetermined number of occurrences. The communication unit (126) transmits, to a communication apparatus (16), notification information based on the comparison result if the difference in the number of occurrences of operating states is equal to or greater than the predetermined number of occurrences. Thereafter, the setting unit (127) changes the threshold value on the basis of a threshold value setting request received by the communication unit (126) from the communication apparatus (16). |
