SHEET 01 · Case story

Compare locations to see which store uses more electricity.

The retail chain brings meter data from its locations together in usage rankings, anomaly alerts and reports. Headquarters can identify stores with higher readings and then review operating and equipment conditions.

SHEET 02 · Challenge and response

From the site problem to a system approach.

  1. 01The challenge

    Energy records are scattered across sites, so cross-location comparisons and anomaly follow-up take substantial manual compilation.

  2. 02The system approach

    Create multi-site energy overviews, rankings, anomaly alerts and reporting flows.

  3. 03Reported outcome

    Help managers spot locations that may need review and set improvement priorities.

SHEET 03 · Architecture

System architecture and data flow.

Meter data from each site enters the platform, which provides energy comparisons by site, area and equipment. Source diagrams retain some original Traditional Chinese labels.

SHEET 04 · Wiring and hardware

Wiring diagrams and hardware configuration.

The diagram outlines data flow between site signals, edge devices, the network and the platform. Confirm installation and connection scope before work begins.
