Node

A node (or “knot”) in network terminology refers to a physical or virtual point that can send, receive, or forward data. In connected buildings, it serves as an essential unit for enabling communication between devices such as sensors, actuators, or gateways. Nodes help distribute data efficiently across the network and ensure the functionality of interconnected systems.

Nodes utilize wireless technologies such as Bluetooth Low Energy (BLE) or Zigbee to connect with other devices and transmit data. In mesh networks, nodes directly interact with one another and leverage the self-healing function to use alternative communication paths during disruptions. This capability makes nodes particularly suitable for complex and scalable networks, enhancing the reliability of data transmission.

In practical applications, nodes serve as building blocks for controlling and monitoring in various types of buildings. Sensors like motion or CO₂ detectors act as nodes, capturing real-time data and forwarding it to centralized systems. Similarly, actuators such as smart thermostats or lighting systems function as nodes, receiving data and executing control commands. In industrial facilities, nodes support the monitoring of equipment and enable precise, dynamic control of operational workflows.

Cloud-based platforms enhance the functionality of nodes by enabling centralized management and analysis of network data. Additional technologies like Over-the-Air (OTA) updates ensure that nodes can be continuously updated to implement new features and maintain high security standards.

Nodes are a critical component of connected systems in building management. Their versatility and reliable communication make them a foundation for stable data transmission, resource conservation, and flexible utilization of modern technologies in buildings.
