eWatt – Every Watt Tells a Story

Plug in and the service works!
The reader connects directly to the electricity meter's HAN port, requiring no installations, cabling, or integrations. The device connects automatically to the mobile network via its own SIM card, so Wi-Fi is not needed.
Accuracy that quarter-hourly and hourly data can't match
eWatt measures electricity at 10-second accuracy, so short power spikes, wrong timings, and abnormal usage don't disappear into averages. This makes visible the phenomena that determine consumption but remain hidden in traditional monitoring.
Device-specific consumption without device-specific meters
eWatt identifies different devices' and systems' electricity usage based on their unique electrical fingerprint. This way, the entire factory's or property's device-specific consumption becomes visible without expensive device-specific sensors or installations.
Over 30 metrics from a single meter
Consumption alone isn't enough to understand what's happening with electricity. eWatt continuously reads over 30 different metrics from the electricity meter, such as power, currents, voltages, phase-specific differences, and reactive power, which reveal anomalies related to power quality and loading.
You'll understand electricity more comprehensively than ever before.
Real-time data that's stored
Data is visible in real-time but also stored for later review. We compile electricity data into one clear interface that production, maintenance, and energy management can use as a shared foundation. This way, changes, anomalies, and actions taken can be verified afterwards. We have one of Europe's largest electricity data banks.
Data security at European top level
Electricity data is transferred and stored according to EU and Finnish requirements, and data is always owned by the customer. All information is protected, traceable, and reliable.
Not a step, but a leap towards ESG goals
When electricity usage anomalies, peak power, and current spikes are brought under control, buildings run more smoothly and predictably. This improves energy efficiency and creates a verifiable foundation for ESG requirements and ISO 50001 energy management.

Our Story

How electricity data will change energy efficiency

In 2022, in Jyväskylä, two founders saw a problem that could no longer be ignored.

Europe's energy markets were changing rapidly. Geopolitical crises, price volatility, and growing energy efficiency requirements forced property owners to look at their energy usage in a completely new way. Yet many still lacked the most important thing: reliable and accurate electricity data.

Without data, energy efficiency easily remains just a goal.

We believe that real change starts with knowledge. That's why we decided to build a solution that makes property electricity consumption transparent, understandable, and above all actionable. We developed an easy-to-deploy, cost-effective service that collects and refines electricity data from different property types – from offices and commercial properties to schools and sports centers.

When electricity consumption becomes precise data, new opportunities arise:

Consumption optimization
Identifying unnecessary energy use
More efficient property management
Significant cost savings

But for us, it's not just about individual properties.

Our goal is to build an electricity data-based view of energy usage across all of Europe. When the energy consumption of millions of square meters becomes analyzable data, we can identify efficiency potential, guide better decisions, and accelerate the energy transition.

Today eWatt is available in Finland, Sweden, Denmark, the Netherlands and Belgium.

We don't just monitor energy consumption – We use electricity data to change the way Europe uses energy.

Our goal is to become the market leader in energy data management in Europe.
