Power Control Monitor (GUDE) - Blockchain-based Monitoring
Sector: Tertiary sector · Industry: Information technology · Organisation: Gude Systems GmbH / Blockchain Reallabor · Maturity level: Concept
Gude Systems' Power Control Monitor devices monitor and control mission-critical IT equipment in data centers and are used in the Blockchain Reallabor for technical monitoring of IT and AV installations. The system records sensor data and switching operations in a tamper-proof manner using blockchain technology. This enables new services such as digital product passports and innovative insurance models.

Description
Gude Systems (Bad Homburg) develops intelligent power distribution systems (Smart PDUs) for data centres. The Blockchain Reallabor Huerth (Fraunhofer FIT) integrated Gude PDUs with a blockchain interface: energy consumption data is written directly on-chain from the hardware component — immutable, timestamped, machine-readable.
Data centres face a fundamental sustainability problem: energy consumption is measurable, but reports can be adjusted retrospectively. For CSRD reports, green electricity certificates and PUE calculations (Power Usage Effectiveness), operators need immutable, trustworthy energy data. The Gude blockchain solution: Gude PDUs measure the energy consumption of each socket; data is transmitted in real time via API to the blockchain; smart contracts can trigger alarms if consumption limits are exceeded. The Blockchain Reallabor documented this use case in the demonstration centre: visitors can see live how energy measurement data is recorded on-chain. Practical relevance: EU taxonomy and CSRD require quantifiable, verifiable energy data for sustainability reporting. Blockchain-anchored PDU data is directly auditable — no manual aggregation from different sources needed.
Perspectives
B2B — organisations perspective
Data centres and co-location providers can automatically generate verifiable, tamper-proof energy consumption data for CSRD reports, EU taxonomy compliance and green electricity certificates using Gude blockchain PDUs.
Employees perspective
IT administrators and facility managers benefit from automated, audit-proof documentation of their systems, reducing manual logging tasks. At the same time, they need to develop new skills in handling blockchain-based monitoring systems.
Benefits
General
- Immutable and trustworthy documentation of operational data creates new opportunities for compliance and certification.
- Automated creation of digital product passports reduces manual documentation effort.
- Basis for innovative insurance models based on real operational data.
B2B — organisations
- Reduced costs for compliance audits through automated, immutable documentation.
Employees
- Less manual logging work through automated blockchain-based data collection.
Challenges
General
- Integration of existing monitoring infrastructure with blockchain systems requires technical expertise and investment.
- Scalability of the blockchain solution must be ensured for continuous data collection from many devices.
B2B — organisations
- Legal uncertainties regarding the recognition of blockchain-based documents in compliance procedures.
Employees
- Need for training in blockchain technologies and new monitoring workflows.
Technology foundation
The system uses a permissioned blockchain technology that grants access only to authorised participants. This type of blockchain is particularly suitable for industrial applications as it offers greater control over network participants while ensuring the immutability of stored sensor data.
Implementation examples
Blockchain Reallabor monitoring integration
The company wanted to explore how proven monitoring hardware could enable new business models through blockchain integration. Particular interest was given to developing trustworthy data foundations for insurance products and digital certifications.
Gude Systems integrates their Power Control Monitor devices into the Blockchain-Reallabor for technical monitoring of IT and AV installations.
Within the framework of the Blockchain-Reallabor, Gude power distribution units are used for continuous monitoring of critical parameters in IT environments. The devices collect data such as power consumption, temperature, and other environmental parameters and transmit these to a blockchain system. The aim is to develop new service models such as digital product passports and innovative insurance solutions based on audit-proof stored operational data.
Conventional monitoring data can be manipulated and therefore does not provide a sufficient basis of trust for critical business processes. Blockchain integration solves this problem through immutable data storage and enables new data-based services.
