About us

Own-developed measurement and monitoring system for energy data

In our lives, there is an increasing demand for the use of renewable energy sources and for smart regulation of consumers. In order to stop or reduce rising energy costs, we have decided to develop a whole new complex measuring and monitoring system.

Onlinemonitoring is an innovative and complex system that helps users optimise their energy consumption and energy production. In developing the system, we have placed great emphasis on user experience, ease of handling and reliability.

Our goal was to create a useful solution for everyone, which helps reduce energy consumption and costs while increasing user comfort and safety.

Onlinemonitoring, OLM, is produced by Gelka Kft in Hungary. Each firmware and central measuring software solution is our product. The devices are own-designed and use products from known, reliable components manufacturers in their circuits.

Long-term stable operation is one of the main aspects in the design of our products. All OLM devices are tested individually during quality control because we want our users to use our products for many years and to benefit from them.
