Energy Consumption Monitoring System: An IoT Startup Tracking Electricity Use per Machine

Businesses know their total electricity bill but not which machine spent the money at what hour; you can sell that visibility.

Quick answerA monitoring system that measures consumption per machine, line or floor with current sensors and energy analyzers fitted to electrical panels, and detects idle running and abnormal consumption. It is sold to factories, hotels and commercial buildings through hardware installation and a monthly software subscription.

What problem does it solve?

For factories, hotels and commercial buildings, electricity is one of the largest cost items. Yet most businesses only see the monthly bill from the main meter; they do not know which machine runs idle, which shift wastes energy or which device draws more power as it heads toward failure. Because the impact of efficiency investments cannot be measured, decisions become harder. Reactive energy penalties and contracted power overruns are also usually noticed only after the bill arrives.

Target customers

  • Medium and large manufacturing plants
  • Hotels and holiday resorts
  • Malls, business centers and office buildings
  • Cold storage facilities and logistics centers
  • Energy consulting and efficiency firms
  • Retail and restaurant chains

How the product works

Current transformers and energy analyzers fitted to electrical panels without cutting cables measure current, voltage, active-reactive power and consumption. Data is sent to the cloud via Modbus or a wireless gateway. The dashboard shows consumption per machine, line, floor or department in real-time and historical charts. The system automatically flags after-hours consumption, idle machines and devices deviating from their normal profile. It sends alerts when approaching reactive ratio and contracted power limits, and when production quantities are entered, it calculates energy cost per unit produced.

What the first version (MVP) needs

  1. Metering hardware: Panel-level measurement with current transformers and energy analyzers
  2. Data collection: Cloud transfer via Modbus/MQTT gateway
  3. Consumption dashboard: Real-time and historical charts per machine, line and floor
  4. Waste detection: Report on after-hours and idle consumption
  5. Reactive and power alerts: Notifications when approaching limits
  6. Anomaly detection: Flagging consumption that deviates from the normal profile
  7. Cost report: Tariff-based cost and energy per unit produced
  8. Export: PDF and Excel reports

Revenue model

  • Metering hardware sales and panel installation fees
  • Monthly software subscription per metering point
  • Energy efficiency analysis and consulting reports
  • Reseller and white-label licensing for energy consulting firms

Why now?

As electricity weighs more heavily on business budgets, measuring consumption becomes essential for savings. Manufacturers exporting to Europe face pressure to report carbon and energy data; per-machine metering is the foundation of that reporting. Clamp-on sensors that install without cutting cables and cloud-based dashboards have lowered installation costs. Many mid-sized facilities in Turkey still look only at main meter data, which opens room for a local, quick-to-install, Turkish-language solution.

End-to-end roadmap

  1. Validate the idea (1 week): Interviews with target customers, competitor and pricing research; we sharpen the idea together in a free pre-analysis.
  2. Scope and design (1–2 weeks): MVP feature list, screen designs and technical architecture; written scope and quote.
  3. Build the MVP (10–14 weeks): Staged development with weekly demos and a test environment; the source code belongs to you.
  4. Pilot (2–4 weeks): Real use with the first customers, feedback and fixes.
  5. Launch and grow (ongoing): App Store and Google Play release, website and SEO, payments and subscriptions, new modules.

Timelines are estimates; they are fixed in a written quote once the scope is clear.

Risks and how to handle them

  • Electrical safety: Panel installations should be done by a licensed electrician, and non-invasive metering methods that do not cut cables should be preferred
  • Proving savings: Take baseline measurements before installation to provide a before-and-after comparison, and do not promise guaranteed savings
  • Varying device protocols: Support standard protocols such as Modbus for compatibility with existing analyzers and run a site survey beforehand

Frequently asked questions

Does installing an energy consumption monitoring system stop production?

With split-core current transformers that do not require cutting cables, most installations can be done without stopping production; panel work should still be planned under a licensed electrician's supervision.

Does the system guarantee savings?

The system makes visible where waste occurs; savings depend on the actions the business takes based on this data. That is why a before-and-after comparison with baseline measurement should be offered instead of a guaranteed savings promise.

Can it work with existing meters and analyzers?

Data can be read from existing devices that support standard protocols like Modbus, reducing the need for new hardware and the installation cost.

Who should I target as my first customers?

Mid-sized manufacturing plants with high electricity bills, many machines and shift work see the value of metering fastest; you can then expand to hotels and commercial buildings.
