The intelligent systemintegrator




Systemintegration for different building engineering available. In case of numerous industrial and office buildings many engineering systems from the past decades are mixed with todays modern engineering. Our work includes the unfolding of the possibilities given by the old and new systems and after the planning we also accomplish the full integration. If needed we also install our own equipment, but we try not to disrupt the current system. Because of that we are able to ensure a personalised cost-efficient system at a significantly lower price than offered on the market. During the implementation, we take the exact needs of the user into account, then we examine who wants to use it ,and what the system should be capable of, and we also provide an easy-to-use, user-friendly interface.


The service is able to cope with all the smart home tasks that arise:

  • Shutters, shading
  • Towel dryer control
  • Alarm integration
  • Water leakage monitoring
  • Irrigation system control
  • Gate opening/ closing control
  • Electricity network control, supervision
  • Camera system integration
  • User-friendly environment
  • Remote control, access, alarm
  • Application (iOS, Android)

Our product contain complete energy audit of the property(s), which is more than the ISO:50001 standard. Our goal is to find those parts of the property, where energy consumption is not optimal, and increase the efficiency in these areas:

  • Heating/ cooling control
  • Lighting control
  • HMV
  • Doors and other closing systems control
  • HVAC
  • Water measurement, alarm
  • Electricity network control
  • Behavioural analysis and learning


With this electrical load optimization and by smoothing consumption curves, electricity costs can be significantly reduced. Our product offering for monitoring and / or intervening environment.
