Power monitoring device and power analysis method

A power analysis method for a power monitoring device, the power monitoring device comprising a transceiver, a storage and a processor, the transceiver being communicatively connected to a power meter and receiving a plurality of pieces of power consumption information from the power meter, the power meter being installed on a power line of an electric device, the storage storing a piece of power specification information of the electric device and a piece of user and environment information associated with the electric device, the processor being electrically connected to the transceiver and the storage, and the power analysis method being executed by the processor and comprising the steps of:

• generating a piece of user behavior feature information according to the power consumption information;
• retrieving a piece of key feature information from the power specification information, the user and environment information and the user behavior feature information so as to generate an inform message according to the key feature information;
• and
• enabling the transceiver to transmit the inform message to a user device associated with the electric device.
