Electricity System — Smart Energy Billing & Monitoring

Project at a glance

The Smart Lead Tech team built Electricity System as a complete platform for energy providers, residential-tower owners and industrial parks. It connects smart meters with a cloud data layer and a detailed admin console, so operators can monitor every subscriber’s consumption and bill it accurately — with no human error.

The challenge

• Continuous meter readings without data loss during connectivity hiccups.
• Multiple tariff models (residential, commercial, industrial) and tiered consumption brackets.
• Reliable periodic billing with delivery of invoices to subscribers.
• Automatic detection of leakage or anomalous consumption.

What we built

• An IoT Gateway ingesting meter telemetry over MQTT and persisting to TimescaleDB.
• A Laravel 11 backend that runs subscribers, meters and tariff-based billing.
• A React.js admin with live consumption charts per subscriber.
• An alerts engine that flags anomalies and pushes notifications via Push/SMS instantly.

Outcome: billing errors down 96% and monthly invoicing collapsed from days to a few minutes.
