Understanding the language of electricity
BETTER INSIGHTS BETTER DECISIONS LOWER COSTS
Real-time energy monitoring and electricity analytics for commercial properties.
Identify hidden energy waste, reduce electricity costs, detect power quality issues, and improve operational efficiency with 10-second electricity data.
From Insights to Savings
Most energy monitoring systems provide data, but not clear answers.
As a result, turning energy data into measurable cost savings often takes months or even years.
With the eWatt Reader, electricity data is collected automatically every 10 seconds. This helps us identify savings opportunities that can often be acted on the very next day.
Your job? Just book a meeting. We'll take care of the rest.
The result: Faster savings, lower electricity costs, and better operational decisions.
Understand Your Electricity. Reduce Your Costs.
Start Saving Immediately. Stay Optimized Continuously.
Using the proprietary eWatt Reader, we collect electricity data every 10 seconds and build a detailed picture of how energy is used across your facilities.
Our experts review and analyze the collected data to identify inefficiencies, unnecessary consumption, power quality issues, hidden operational risks, and opportunities for immediate cost savings.
After the analysis, you receive a clear report with actionable recommendations that can help you start reducing your energy costs right away.
Once the initial recommendations have been delivered, we continue monitoring your facilities around the clock. Our team tracks energy performance, detects anomalies, identifies new optimization opportunities, and notifies you whenever action is required.
You no longer need to spend time monitoring meters, reviewing energy data, or searching for issues yourself. We handle the monitoring, analysis, and reporting, allowing you to focus on your business while we help keep your energy costs under control.

How it works
Connect the reader
Order the eWatt reader to your site. Connect it to the electricity meter's HAN port. The device gets power from the meter and connects to the network via its own SIM card. Suitable for both low and medium voltage meters.
We collect data
Over two weeks, we collect electricity data at 10-second accuracy. Afterwards, we review with you where power spikes originate, whether there is unnecessary base load consumption, whether devices show anomalies, and what the electricity quality is like at the site. You'll see concretely what can be improved immediately and what over a longer period.
Continuous Monitoring & Support
After reviewing your energy data, we provide a clear report with actionable recommendations to help reduce costs and improve efficiency. From there, we continuously monitor your facilities, detect anomalies, identify new savings opportunities, and notify you immediately if any issues arise. You can focus on your business while we take care of the monitoring.
Book a meeting to discuss your energy goals and find the plan that suits your business best.
Book a MeetingTraditional Monitoring vs. eWatt
| Feature | Traditional | eWatt |
|---|---|---|
| Measurement accuracy | 15 min or 1 h interval | 10-second accuracy — real-time |
| Measured quantities | 1 quantity: consumption (kWh) | 15+ quantities |
| Voltage (L1/L2/L3) | Not available | Yes — all three phases |
| Current (L1/L2/L3) | Not available | Yes — all three phases |
| Current fed to grid | Not available | Yes |
| Active / Reactive / Apparent power | Not available | Yes — continuous tracking |
| Power factor (cos φ) | Not available | Yes |
| Current spikes | Not available | Yes — detected in seconds |
| Base load monitoring | Not available | Yes — automatic alerts |
| Automation anomalies | Not available | Yes — from September 2026 |
| Alerts & notifications | No | Yes — from September 2026 |
| Installation verification | Manual / delayed | Immediate, based on data |
| Maintenance speed | Maintenance doesn't know when the issue occurred, delayed investigation | Information sent directly to maintenance |
| Historical data stored | Only total consumption stored | Data stored with 15+ quantities |
| Total consumption tracking | Separate monitoring service — extra cost | Included in eWatt — no separate service needed |
| Forecast data quality | Poor (1 quantity, infrequent) | High (15+ quantities, 10 s) |

eWatt is compatible with these meter models
| Manufacturer | Model | Connection | Type | Network companies / notes |
|---|---|---|---|---|
| Aidon | 6000-sarja (6141, 6161, 7534) Base model, low voltage | P1 | Low voltage | Elenia, Helen, Caruna, Vantaan Energia and others. The most widespread model in Finland. |
| Aidon | 6000W / 6800 CT model | P1 | Current transformer / Medium voltage | For larger properties and industrial sites (CT measurement). Used by several network companies. |
| Landis+Gyr | E360 (ZMF120) Base model, low voltage | P1 | Low voltage | HSY/Helen Sähköverkko, Turku Energia, PKS, Savon Voima. Common in southern Finland. |
| Landis+Gyr | E360 CT (ZMF320) CT model | P1 | Current transformer / Medium voltage | Properties and industry, CT connection. Used by several regional network companies. |
| Kamstrup | OMNIPOWER Multifunction AMI | P1 / HAN | Low voltage / Current transformer | Järvi-Suomen Energia, EPV Alueverkko and some smaller network companies. |
| Iskraemeco | AM550 DLMS/COSEM based | P1 | Low voltage | Some smaller regional network companies. Slovenian manufacturer, more limited use. |
| Sagemcom | T210-D / SICONIA French manufacturer | P1 | Low voltage | Some network companies acquired as part of AMM expansions. Limited presence in Finland. |
