Energy monitoring and BLE home automation for Schneider Electric
As a consultant at Capgemini-Sogeti High Tech, I built interfaces for Schneider Electric’s Wiser Energy platform: energy consumption monitoring and photovoltaic production tracking for residential installations, delivered as both internal and end-user applications across EMEA.
Two products, two framework generations
The platform shipped as WiserEnergy on AngularJS and WiserOne on Angular. Working across both meant keeping shared concepts consistent while the codebases had genuinely different idioms — and it is where the case for migrating rather than maintaining two generations stops being theoretical.
Two audiences, too: internal tools for people who use them daily and know the domain, and end-user applications for residents who did not choose the software and will never read documentation. The same data, presented with different assumptions about what the reader already knows.
Home automation over Bluetooth Low Energy
I delivered control of BLE actuators — light bulbs and shutters — through a web application deployed to Android and iOS via Ionic Cordova.
BLE is the interesting constraint. It is not a request/response transport: devices drift out of range, pairing fails intermittently, and an operation that succeeded a moment ago may not now. The interface has to represent a device as probably in a state rather than pretending it knows, and it has to recover without making someone restart the app.
Technical environment
Java 8 behind React, Angular, AngularJS and TypeScript on the front end, NodeJS, ThreeJS for visualisation, and Ionic Cordova for the mobile build.
