Single Pair Ethernet in Building Automation: A Successful SPE Application
At JUMO’s new SENSILO plant in Fulda, Single Pair Ethernet (SPE) demonstrates just how simple and powerful the technology already is in real-world applications today.
For smart indoor climate monitoring, JUMO relies on a seamless SPE infrastructure — from the sensor level all the way to the cloud. The result is a stable digital measurement chain for temperature, humidity, and CO₂ that is efficient, space-saving, and future-ready.
Single Pair Ethernet in Practical Use at JUMO
With its new SENSILO plant in Fulda, JUMO is embracing modern building automation and showing the potential that Single Pair Ethernet already offers in real applications. In the visitor and presentation areas of the facility, the indoor climate is continuously monitored. Key parameters such as temperature, relative humidity, and CO₂ concentration are recorded.
The data is transmitted digitally via a continuous SPE infrastructure to the building climate control system and to the JUMO Cloud. There, it is visualized, recorded, and made available for further use. This creates a modern, fully digital solution for indoor climate monitoring.
End-to-End SPE Infrastructure from the Sensor to the Cloud
The solution combines JUMO multisensors, SPE switches from Weidmüller with Power over Data Line (PoDL), robust SPE cables from Dätwyler, and fast installation by Kerbl GmbH & Co. KG. This combination shows how SPE components already work together reliably today and can be used efficiently in building automation.
One key advantage is that data and power are transmitted over just a single pair of wires. As a result, no additional power cabling is required. At the same time, SPE cabling supports distances of up to 500 meters, offers high resistance to interference, and enables simple commissioning.
Less Cabling, Greater Efficiency
The JUMO application clearly demonstrates the benefits of Single Pair Ethernet in building automation: reduced cabling effort, compact infrastructure, fast installation, and seamless digital communication. Especially in modern buildings, where efficiency, space savings, and ease of installation are critical, SPE opens up new possibilities.
The application also shows that sensor technology, data transmission, and power supply can be implemented with SPE in a particularly cost-effective and user-friendly way.
Collaboration as a Key Success Factor
A central success factor in this project is the close collaboration within the Single Pair Ethernet System Alliance. Manufacturers and technology partners are combining their expertise and making SPE usable together in real applications — interoperable, robust, and practical.
The JUMO example clearly illustrates how innovation is driven by collaboration and how Single Pair Ethernet is already helping to make building automation simpler and more efficient today.
