Fast, accurate, and versatile IoT sub-meter

The universal, smart electricity sub-meter Energomaster can be used for a range of applications where fast and accurate information on power consumption or production is needed, optionally complemented by universal digital inputs and outputs, i.e. for monitoring and production control.


Energomaster is the ideal solution for Industry 4.0, smart city, microgrids, monitoring efficiency and other clever energy solutions of the 21st century. Data measured by Energomaster is sent via a communication interface (optional LTE, WiFi, LoRaWAN, etc.) to monitoring and management systems at adjustable intervals (5 seconds – 60 minutes). The MQTT and CoAP standards are used for data transmission.

  • Monitors electricity consumption accurately, in real-time 

  • Monitors voltage, current, power, energy, and power failures

  • 3 phases, up to 9 individual circuits, and two digital inputs monitored by one device

  • Two digital outputs

  • Wide range of communication interfaces (per client’s request: LTE, WiFi, LoRaWAN and others)

  • Industry standard interfaces for connecting to monitoring and management systems (MQTT, CoAP, DLMS/COSEM)


Full featured Internet connected smart meter with a small footprint and up to 9 individually measured circuits. Flexible, for a variety of applications of all sizes.
