Synerlink, monitoring silent Linky meters
Enedis' Linky monitoring team in the Alps tracks the meters that stop communicating. We built Synerlink, the tool that brings substations, meters and field work together.
- The need
- When a Linky meter stops sending data, you have to find out why. A substation, a data concentrator, interference on the line. Tracking relied on about ten Excel exports cross-checked by hand, with thousands of rows.
- What we built
- A substation view with collection and maintenance indicators, assignment and bulk actions
- A meter view with dedicated lists for silent meters and alarms
- Maintenance tracking for concentrators, meters and interference
- Analysis files with their status and history
- Field filtering jobs with photos and the meters involved
- A map of meters, substations and filters, with data imports and CSV and Excel exports
- How we worked
- Volumes are large and lists had to stay fast. We compute summary tables on each import, added targeted indexes and typo-tolerant search in PostgreSQL, and split exports into batches. We also had to fit the internal IT of Enedis, its access roles, versions and application isolation.
- Technologies
- React
- Vite
- Tailwind CSS
- MapLibre
- PHP
- PostgreSQL
- Playwright
- The result
- The Chambéry team uses Synerlink every day. Enedis has rated it a potentially critical application, useful to keep control of the meters in case of a cyberattack, and it is the base for a new project. We also build other tools for the regional control centre, such as Info Conduite.
