Edge IoT controllers + cloud AI for industrial energy. A Raspberry Pi 4 + L&T HT meter via Modbus RS485. ToD tariff compliance + MD-floor automation + PF rebate captured in software.
The PowerIQ dashboard — 5-minute HT metering, ToD tariff slabs, MD-floor automation, and PF-rebate capture.
A Raspberry Pi reads the HT meter via Modbus. Greengrass pre-processes at the edge. An MQTT broker forwards to the cloud. A time-series store captures 5-minute granularity. A tariff engine + forecast ML decide load actions. Commands flow back to the edge controllers. ESG reports export audit-ready.

An HT power-consuming industrial site. Time-of-day tariff penalties they couldn't shift, MD penalties they couldn't avoid, PF rebates they were leaving on the table. Six months later, ~20% lower bill.
