RT-RK – Supplier of the Internet of Things (IoT)

Novi Sad, Serbia – November 19, 2014 – Founded as a strong real-time software and embedded solutions R&D company, RT-RK embarked on the home automation years ago. The main route of knowledge acquisition: provision of design services for world-known customers and development of own product portfolio, has had the company mastered enterprise and web technologies, communication protocols, and embedded development. Projects for customers such as: smart starter, innovative sensors, home automation node, smart TLD control, turn-key remote management solution, and solar powered smart road marker – deployed and field proven – have assured the company’s home/industrial automation direction and given rise to development and branding of own IP home automation technology. The flexible and scalable technology to build home automation solutions is codenamed OBLO.


From a stand-alone home automation system including smart retrofit nodes and remote controllers, via local network mode including: home automation nodes, gateway products, and applications for home automation clients, OBLO has evolved to a cloud-based end-to-end solution.

Today RT-RK offers four big building blocks forthe IoT domain licensing:

  • Solutions for the nodes based on ZigBee, with a Bluetooth Low Energy solution to be demonstrated at CES 2015, and Z-wave and 868 MHz standard solutions upcoming in 2015
  • OBLO Home Manager software as the basis for any-type gateway supporting a wide range of commercially available clients (sensors, actuators), easy-to-install Linux libraries providing interfacing of the nodes with mobile/tablet devices inside the home, as well as connection to the Internet
  • INSIGHT as the technology providing cloud–based IoT services, from basic functions such as account management, over remote access via the Internet e.g. mobile application, to complex intelligence algorithms and analytics of big-data mining executing on servers
  • Applications for mobile phones/tablets for iOS and ANDROID with the basic function of access to the nodes via OBLO Home Manager in the local network and over the Internet. A special attention has been put into UI development to make the applications simple and intuitive to use.

Steady growth of OBLO sales with ALING-CONEL

ALING-CONEL is a local manufacturer and retail supplier of OBLO smart home products: smart dimmers, smart outlets, remote and scene controllers. The biggest in the region, it scores sale of 2K smart OBLO nodes in 2014, with more new products announced. Following the demand of the market, the new products will include: smart plug, battery operated scene controller, and IP shutter. The smart plug is a moveable OBLO node that makes any classic outlet a smart one, with the features of power consumption monitoring and appliance power control. The scene controllers set lighting constellation of the home to a predefined lighting scene: lights on/off and required light dimming levels.

ALING-CONEL supplies big retailers such as Promont and Elektromanija in Belgrade, Elnos in Belgrade and Banjaluka, Elsatrade in Sarajevo, Centrum Trade in Banjaluka, Elektroelement in Novi Sad, Nis, and Skopje, and AMI Company and Halogen in Novi Sad. Via ALING-CONEL companies with own home automatization solutions such as Control4 get supplied with OBLO intelligent products.

Not state-of-the-art but a new stage of the technology

OBLO Smart City

Connected, smart, power consuming appliances and the technology thereof is not state-of-the-art but a whole new technology stage. As energy saving awareness arises globally it opens a whole new scope of potential usage of OBLO technology based solutions. So-called Smart City is one of the favorite projects of computer engineers. The aim is to solve the myriad of everyday problems of urban living with the help of cost-effective intelligence.


At the VDE Kongress 2014 RT-RK presented a novel approach for street lighting automation, with the primary goal to decrease the level of light pollution and electric energy waste. The concept enables the street lights, RF enabled, to be automatically switched on or off triggered by a presence of humans or moving vehicles.

One problem with the model networked city: The more things spark through the area, the more often it comes to interference. OBLO takes the benefit of the fact: Radio frequency (RF) enabled light nodes create a sensible radio network, where the absorption by molecular resonance of an object of detection is a major factor affecting the radio propagation. OBLO solutions exploit the known fact that the object of detection interferes with radio signals within the established radio network. Introduced irregularities in the radio propagation pattern, expressed in a form of received signal strength indicator’s (RSSI) variations, point to a possible presence of the object. Analyzed irregularities are distributed locally and each streetlight node makes an automatic selection of the functional state accordingly, e.g. switches the light on/off depending on the detected presence, eliminating the need for a centralized controller as in the case of smart home systems. The algorithm is optimized to execute in real time even at low processing power systems’, almost immediately, when the object appears passing, illuminating the street, then turning the light off or dimming down when the moving object has no longer been detected.
