Welcome to
Our products aim to provide cutting edge solutions to companies, research teams and solar plants who wants to reduce and meter their energy consumption.

OPENZMETER
oZm | Products
The oZm3 is our new improved oZm for three-phase networks. Ready for home, industrial installations or research laboratories. It can measure up to 320 VAC or 440VDC line voltages.
The oZm Sun is designed to measure the quality of the energy produced in solar plants
oZm devices are designed with the highest standards of quality.

oZm | 3Phase Pro
Our master device. Designed to monitor a huge amount of energy variables and valuable information in your electrical consumption.Some features of oZm!

ENERGY SAVING
Monitor your home
electric energy to understand your pattern usage and explore your daily consumption.

PROFESSIONAL HARDWARE
Built with reliable components to get professional and accurate measurements to comply with standards.

POWERFUL API
We built a powerful api to query ozm and get detailed responses for every computed parameter.

BEAUTIFUL GRAPHS
oZm provides nice graphs with zoom, pan, filter and other capabilities to show clear and beautiful visualizations.

OPENSOURCE
The project is opensource and openhardware so you can contribute!

REALTIME COMPUTATION
oZm comes with RealTime linux ARM board and STM32 microprocessor, allowing realtime acquisition and processing of data.

INTUITIVE DASHBOARD
Non-experienced users can track their electrical information at a glance with minimal knowledge of power systems.

TELEGRAM INTEGRATION
Awesome!!! You can talk to your ozm and receive reports or notifications when something is wrong in your home.
