IoT (Internet of Things)

The Internet of Things (IoT) describes a network of smart devices, known as IoT devices, which are connected to each other via sensors, actuators, and software in order to exchange data in real time. In building automation, IoT enables the automated control and monitoring of processes such as heating, lighting, and air conditioning. This reduces energy consumption, improves resource utilization, and increases comfort.

IoT devices continuously collect measurements such as temperature, humidity, or energy consumption and transmit them to central control systems via wireless technologies such as Bluetooth Low Energy (BLE) or Wi-Fi. In larger building structures, mesh networks are often used, which utilize alternative communication channels through their self-healing function to ensure reliable data transmission. This continuous processing of sensor data enables automated adjustments, such as regulating lighting or air conditioning systems based on room occupancy and usage patterns.

The fields of application for IoT in buildings are diverse. In office buildings, IoT devices optimize energy consumption by adjusting lighting and air conditioning to the presence of users. In warehouses, IoT sensors support the monitoring of technical equipment and enable predictive maintenance to minimize downtime. Residential buildings benefit from IoT solutions through mobile control options for heating and security systems, which increase comfort and save energy.

Complementary technologies such as cloud-based platforms and over-the-air (OTA) updates expand the functionality of IoT systems. OTA updates ensure that control units are regularly updated with new security policies and features, while the aggregation of sensor data enables detailed analysis and optimization of building functions. These technologies support efficient resource utilization and facilitate the implementation of sustainability concepts.

The Internet of Things connects devices and systems in building automation, thereby laying the foundation for smart buildings. The integration of IoT technologies enables energy-efficient processes and convenient usage concepts.
