Key innovative technologies for I4.0 are Internet of Things (IoT), Cyber-Physical Systems (CPSs), self-organizing machines (M2M), cloud computing, big data and Mixed Reality (MR). Microsoft HoloLens2 (HL2) is the new MR revolution for Industry 4.0. The proposed study addresses the potential of Node-RED IoT platform and HoloLens2 for interconnecting virtual and real things from the current scene in the MR window. The augmented holograms on scenes interface the physical object and link behaviours to them seamlessly and regardless of their heterogeneous technologies. A lightweight framework for interconnecting virtual and real things in HoloLens 2 via Node-RED is proposed. The framework uses open-source tools and standard protocols like IoT protocols, Microsoft WebSocket, MRTK for Unity, HL2 APIs and Node-RED nodes used to interact with Python or ROS processes. More detailed experimental analysis will be performed in the future in order to prove that this framework is enough practicable and stable.
