During the 28th International Power Industry and Renewable Energy Sources Fair ENEX, held on 4–5 March 2026 in Kielce, the prestigious ENEX Award prizes were granted for the most innovative technological solutions in the energy sector. Among the award recipients was Zamel, which received the award for its modern LAVVA unity energy management system.

Modern energy management

LAVVA unity is an advanced electrical energy monitor and manager designed for three-phase installations. The device enables precise measurement of key electrical parameters such as energy consumption, voltage, current, and power on each phase. It also supports bidirectional energy measurement, both energy drawn from the grid and energy fed back into it. Thanks to these capabilities, the solution is particularly well suited for installations with photovoltaic systems and other renewable energy sources.

An important element of the system is Wi-Fi connectivity and cloud integration, which enable remote access to measurement data, analysis of energy consumption, and, importantly, the generation of reports. The data is presented in the form of clear charts, making it easier to monitor the operation of the installation and identify potential areas for optimization.

Smart functions and automation

LAVVA unity also offers a range of features supporting efficient energy management. The system enables the creation of automations based on electrical parameters such as:

– active and reactive power, 
– voltage, 
– current, 
– power factor. 

The device is equipped with three programmable relay outputs that enable control of external devices or electrical circuits. The relays can be used, among others, for:

– managing the operation of energy loads, 

– activating additional devices when surplus energy from the photovoltaic installation is available, or limiting energy consumption when specified power thresholds are exceeded. 

This solution enables the practical use of measurement data to optimize energy consumption in real time. As a result, the total balanced energy reflects the billing profile with high consistency relative to the recorded data.

Additionally, the user can receive PUSH notifications about events, such as exceeding predefined power or voltage thresholds. The device also supports tariffs of all energy providers in Poland, including dynamic tariffs based on prices from the Polish Power Exchange (TGE). Thanks to the energy consumption prediction function, the user can better plan energy usage and optimize costs.

Recognition of innovation

The ENEX Award granted to a product from the LAVVA ecosystem confirms the high technological value of the solution and its importance for the development of modern energy management systems. The distinction also highlights the commitment of Zamel’s IoT department to creating innovative products that support energy efficiency and the development of intelligent energy installations.

The award received at the ENEX trade fair is an important confirmation that the solutions developed by Zamel respond to current market needs and align with the direction of the energy transition. The award was received by Ernest Cichoń, CTO of Zamel. The award is a great distinction and confirmation that the direction in which the company is developing addresses the real needs of the energy market. LAVVA unity was created with the idea of enabling users to consciously manage energy and increase the efficiency of their installations. 

We would like to thank you for recognizing our work and everyone involved in the development of this project. We invite you to view a short photo report from the event:
