Day of Craftsmanship 2025
How Craft Businesses Make the Digitalization of the Analog World Possible
How Craft Businesses Enable the Digitalization of the Analog World
Digitalization begins where most systems still operate in analog mode: on machines, in distribution systems, basements, and technical installations. And that’s exactly where the skilled trades are at home.
On the Day of the Skilled Trades, September 21, 2025, PSsystec honors the central role that professional tradespeople, installers, and craft partners play in the deployment and success of digital technologies. Without precise installation, expert retrofitting, and reliable support, many IoT solutions would simply not be feasible - especially in existing buildings and decentralized infrastructures.
Digitalization needs hands and tools
Although digitalization is often discussed in terms of bits and bytes, it often starts in a very traditional way: with the installation of a sensor, the mounting of a gateway, or the proper placement of an antenna
This is where non-invasive IoT solutions from the SMARTbox portfolio come into play, specifically developed for skilled trades:
- SMARTsens for monitoring faults and conditions in building services
- SMARTsocket for failure detection and remote control of IT equipment, cash machines, ATMs, and gaming machines
- SMARTmodbus for the digitalization of machines and Modbus devices
- IoT Energymonitor for seamless monitoring of electricity, water, gas, and heat
- SMARTtempmonitor & SMARThaccp for temperature and humidity monitoring in cooling areas, storage, and facility operations
New Opportunities for the Refrigeration and Air Conditioning Craftsmanship
Digital solutions are becoming increasingly important in the field of refrigeration technology – whether for complying with legal requirements (e.g. HACCP), preventing product loss, or monitoring cold rooms in real time.
PSsystec offers a specially developed remote monitoring system with the SMARTtempmonitor and SMARThaccp for wireless temperature and humidity measurement, including alerts via email or SMS when threshold values are exceeded. Installation is done using wired sensors or battery-powered wireless sensors and a robust, mobile-network-based SMARTbox – ideal for refrigeration technicians who want to provide their customers with a secure, low-maintenance system.
Currently, several specialist companies in refrigeration technology - including GBS, AIR Kälte, and Kältetechnik Knoll - rely on our wireless temperature monitoring solutions. Together, they carry out retrofit projects in large kitchens, distribution centers, as well as HACCP-compliant monitoring solutions in butcher shops, bakeries, pharmacies, and branch networks - based on the SMARTtempmonitor and SMARThaccp, fully IT-independent and mobile network-based. One of the sources for our refrigeration technology solutions is our distribution partner Frigotechnik, who markets the products and supports customers nationwide.
Together, we ensure that temperatures in refrigerated shelves, storage areas, or bakeries become visible, documentable, and alarm-capable - without wiring, without local IT, and with maximum flexibility.
Why skilled trades and PSsystec are such a great fit
PSsystec’s solutions are optimized for retrofit and upgrading - with a clear advantage for skilled trades:
The plug&play installations take place without any intervention in the existing IT infrastructure and require no on-site configuration. The sensors come pre-configured, and the gateways operate via mobile networks (NB-IoT, LTE-M), requiring no local networks or specialized knowledge - making installation possible without advanced IT expertise, and completely without complex parameterization or programming.
Some key features:
- No downtime: Ongoing operations do not need to be interrupted during retrofittin
- Installation-friendly: Solutions with DIN rail mounting, IP67 housings, and pre-configured wireless mesh
- Independent: No access to customer networks required - ideal conditions for external service provider
- Scalable: Suitable for small businesses, branch networks, or industrial facilities
Partner companies as drivers of digitalization
PSsystec works nationwide in Germany with a steadily growing network of certified craft businesses and distribution partners. Whether electrical engineering companies, facility services, or specialized energy service providers - they are all a central part of the mission:
„We create easy access to non-digitized assets anytime and anywhere."
Example use cases:
- PASM & PSsystec: 24/7 fault monitoring of emergency power systems at over 3000 sites
- Industrial projects: Retrofit of machines and meters via Modbus and M-Bus - no new construction, no IT project
- Cooling and climate technology partners: Temperature monitoring, HACCP monitoring, and real-time alarm management - with the SMARTtempmonitor and SMARThaccp
Funding, Standards, and ESG
Due to compatibility with EN ISO 50001 and eligibility for BAFA funding (Module 3), both customers and craftsmen benefit equally:
- End customers receive funding for energy efficiency measures. Craft businesses unlock new markets in the areas of ESG, digitalization, and energy transparency.
- The solutions meet the highest standards of data security, are PSA-certified (Telekom Security), and can be integrated via REST API into overarching systems - for example, for ESG reporting, CSRD, or benchmarking.
Conclusion: Craftsmanship + Technology = Digital Transformation
PSsystec sees craftsmanship not only as an installation partner but as an active part of tomorrow's digital infrastructure.
Therefore, the Day of Craftsmanship 2025 is not just a celebration for craftsmen, but an occasion to make the interface between technology, energy, and analog reality visible.
Because: the future is digital. And craftsmanship brings it to the wall, into the control cabinet, and onto the construction site.
