Your electricity bill, itemized to the machine.

We instrument factories and buildings with non-invasive smart sub-meters and turn 1-second electrical data into insight you can act on: which machine costs what, what runs while the site is closed, where power-factor penalties come from, and when something starts behaving abnormally.

The install is three jobs: sense (a clamp snaps around your existing cable — nothing is cut, no downtime), measure (a meter computes power and energy every second), and ship (a small gateway sends the data to our analytics, buffering locally when the internet drops).

Every chart in the demos is computed from real meter data — 16M readings from a real factory (HIPE) and a UK household graded against 52 plug-level check-meters (UK-DALE). Nothing is mocked.

How we instrument a factory

Electricity flows down the left; your data flows to the right. Your utility meter keeps billing exactly as before — we only listen, at 1-second resolution instead of 15-minute blocks. That resolution is what makes individual machines visible.

The 30-minute, zero-downtime install

The key component is the current transformer (CT) clamp: a hinged ring that clips around a live cable and senses the current flowing through it. No conductor is cut or touched, and production never stops. A licensed electrician mounts everything in your panel in a single visit.

Four ways to get the data

We are hardware-agnostic: whether you already have a utility smart meter or we install sub-metering, the analytics layer is the same.

Utility smart meter

The DISCOM-installed billing meter you already have

Data: 15/30-minute energy blocks — building-level trends only

Zero-hardware starter tier

CT-clamp retrofit

Clamp-on sensors + smart meter, no rewiring

Data: Per-phase power at 1-second resolution

The 30-minute install for homes, offices and quick factory pilots

Panel sub-meters

DIN-rail Modbus meters on each major circuit

Data: Machine-level power, energy and power factor

Full factory installs — one meter per big circuit

Smart plugs

Per-appliance plug-through meters

Data: Exact per-appliance ground truth

Used temporarily during pilots to calibrate our models

What a factory pilot install involves

A typical pilot covers the main incomer plus around five major machine circuits. Indicative hardware budget — final numbers depend on your panel and circuit ratings, quoted before any work:

ItemQtyIndicative
Incomer CT meter (3-phase, 1-s)1₹12k – 18k
Circuit sub-meters (Modbus DIN)5₹4k – 7k each
Split-core CTs, sized to each circuit~15₹0.4k – 1.5k each
Site gateway (polls, buffers, ships)1₹8k – 15k
4G router + SIM (if no site broadband)1₹4k – 8k
DIN rail, enclosure, wiring, breaker₹3k – 5k
Licensed electrician, one day₹3k – 8k

Every meter we deploy meets accuracy class 1.0 or better, reports per-phase voltage, current, power and power factor at least once per second, and exposes an open local interface (Modbus, MQTT or HTTP) — your data is never locked into a vendor cloud.

We are onboarding pilot factories and residential buildings in India. One panel, one day, and your next month's bill comes itemized.
