අභියෝගය

[Client] runs [N] premises and only saw electricity costs when the CEB bill arrived — a month too late to act. Nobody knew which machines or floors drove the peaks, and bills jumped every time a tariff block was crossed.

Off-the-shelf smart meters needed rewiring by an electrician and showed raw numbers that staff ignored.

අපගේ විසඳුම

We built a clip-on monitor: a split-core CT clamp around the incoming line, read by an ESP32 that sends readings every 10 seconds over MQTT. No rewiring — installation takes about 20 minutes per board.

A web and mobile dashboard shows live kWh, cost in rupees using the CEB tariff blocks, and a month-end bill forecast. An SMS goes out when usage spikes or the forecast crosses a budget the owner sets.
