Abstract: A user device may transmit a request for electricity via a wire to a smart device, where the request includes the universal unique identifier (UUID) of the user device. Upon the reception of the UUID, the smart device may enable an electricity flow to the user device. The smart device may further measure the electricity amount of the electricity flow enabled to the user device based on the UUID. Based on the UUID, the smart device may measure the electricity amount enabled to a specific user device. Consequently, the calculation of electricity cost may be implemented for a specific user device. In some embodiments, the smart device may calculate the electricity cost for different user devices independently. Therefore, the calculation of electricity cost may be more accurate and smart.
