How it works

From meter to insight.

Connect meters

Electricity meters, pulse sensors and current sensors report readings.

Collect

Data travels over LoRaWAN, M-Bus or from existing meters.

See

Dashboards show consumption and load per site and area.

Act

Alarms and reports point to savings and problems.

What you can connect

Frequently asked questions

How does IoT energy monitoring work?

Meters and sensors report consumption to the platform, which stores the history, shows it in dashboards and alerts you when something looks wrong.

Which meters can I connect?

Electricity meters with LoRaWAN or M-Bus, existing meters through interfaces or pulse outputs, and current sensors for load.

Can I see consumption per site or area?

Yes. Organise devices with tags and view them per site, area or customer.

Can I get alerts on abnormal consumption?

Yes. Set alarm rules and receive alerts by e-mail, SMS, Telegram, webhook or MQTT.

Can I compare energy use with the weather?

Yes. You can compare periods and add weather data, and use AI analysis for deeper comparisons.

Can I use the data for billing?

Yes. The readings can form the basis for individual metering and debiting.
