Solution Overview
Problem
Existing power meter technologies lack efficient commissioning methods, particularly for devices with Bluetooth Low Energy (BLE) communication capability, which hinders seamless integration and data exchange between power meters and mobile devices, leading to complexities in monitoring and management.
Innovation Solution
A non-transitory computer-readable storage medium with instructions that enables mobile devices to discover and communicate with power meters using BLE, allowing for commissioning parameters to be transmitted and user interactions to be processed through a user interface, facilitating the establishment of communication links and data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional commissioning methods are used for power meters, then the commissioning process becomes complex and time-consuming, but if BLE communication capability is added to power meters, then new communication protocols and pairing procedures are required which increase device complexity
Solution Approach 1:
The power meter autonomously generates and transmits its own identifier through BLE advertising packets without requiring external configuration or manual intervention. The mobile device automatically discovers and connects to the power meter using this self-generated identifier, eliminating the need for complex manual pairing procedures.
Solution Approach 2:
A mobile device application serves as an intermediary between the power meter and the commissioning system. The application simplifies the commissioning process by automatically discovering BLE power meters, establishing connections, and configuring parameters through a user-friendly interface, thereby hiding the underlying communication complexity from end users.
2Adaptability or versatility
If BLE communication is implemented in power meters, then data exchange between mobile devices and power meters is enabled, but the commissioning process requires additional steps for device discovery and connection establishment
Solution Approach 1:
The power meter is pre-configured with a unique identifier during manufacturing that is automatically advertised via BLE. This preliminary action eliminates the need for on-site configuration steps during commissioning, allowing mobile devices to immediately discover and connect to the power meter without additional setup time.
Solution Approach 2:
The commissioning process skips traditional manual configuration steps by utilizing automatic BLE device discovery and connection establishment. The mobile device application rapidly scans for advertising power meters and automatically connects using the advertised identifiers, rushing through what would traditionally be time-consuming manual configuration procedures.
3Productivity
If manual commissioning procedures are used, then device complexity is minimized, but productivity and commissioning efficiency are reduced
Solution Approach 1:
Traditional manual commissioning procedures (mechanical/key-based configuration) are replaced with wireless BLE communication protocols. The mobile device application automatically exchanges configuration data with the power meter through BLE, substituting manual mechanical configuration steps with automated wireless data transmission, thereby improving productivity despite the added communication protocol complexity.

AI summary
A non-transitory computer-readable storage medium includes instructions for commissioning a power meter that has a Bluetooth Low Energy (BLE) communication capability, the instructions, when executed by one or more processors of a mobile device, cause the mobile device to discover the presence of the power meter by recognizing a signal produced by the Bluetooth Low Energy (BLE) communication capability of the power meter and receive a unique identifier for the power meter. When the received unique identifier matches a unique identifier stored by the power meter, the mobile device will establish a communication link between the mobile device and the power meter using the Bluetooth Low Energy (BLE) communication capability of the power meter and will transmit one or more commissioning parameters to the power meter via the established communication link between the mobile device and the power meter.
