We build the software at the machine and the network edge: edge agents, protocol gateways for OPC-UA, Modbus, and MQTT, retrofit of existing plants, and secure edge-to-cloud pipelines. Operated sovereignly - on your hardware or in European data centers.
Leading companies worldwide trust WZ-IT
The hard part of IoT is not the dashboard, it is down at the machine. Every plant speaks a different protocol, existing machines often have no documented interface at all, plant connectivity is flaky, and OT networks must not simply touch the internet. That layer - devices, protocols, edge - is exactly what we build.
We deliver software that runs robustly at the network edge, makes existing plants connectable, and passes data upward securely and without gaps. Implemented sovereignly with open-source components - on your hardware or in European data centers, without dependence on US hyperscalers.
From the protocol adapter to the secure pipeline - we build the software that makes your plants connectable, robust, and auditable.
Software that runs right at the network edge on an industrial PC, gateway, or existing controller. It collects machine data locally, buffers on connection loss, and decides on site - instead of pushing every reading to the cloud first.
We speak the language of your plants: OPC-UA, Modbus (TCP/RTU), and MQTT, plus S7 communication and Profinet and BACnet bridges. Heterogeneous devices end up in one consistent, cleanly named data model.
Existing machines without a documented interface become connectable - via available PLC registers, added sensors, or reading local HMIs. You get data out of plants that were never designed for the cloud.
Store-and-forward instead of data loss: values are buffered at the edge and reliably transported via MQTT or Kafka into your backend - even over flaky cellular or plant connectivity. No gaps in the history.
Where off-the-shelf software is not enough, we work close to the hardware: resource-frugal agents, drivers for special interfaces, device-side logic with an update mechanism. Stable in the field for years.
Every device gets its own identity and certificate, communication runs TLS-encrypted. Compromised devices can be revoked individually - without shared passwords or open tunnels into the plant network.
Anywhere physical devices and machines need to reliably deliver data and be connected securely.
OEMs and operators who need production data from modern and older plants - for OEE, condition monitoring, and service. We deliver the capture and connectivity layer that the machine fleet reliably feeds.
Make plants from 10 or 20 years of operation digitally connectable without replacing them. Via existing controllers or retrofitted sensors we extract data and create the basis for analysis and remote access.
Energy, water, and heat with distributed meters and radio sensors. Via LoRaWAN we capture battery-powered devices across large areas and consolidate the values into a clean, billing-grade pipeline.
Properties with heating, ventilation, meters, and sensors over BACnet, Modbus, and MQTT. We connect building technology across vendors and create a unified data basis for operations and energy management.
This page owns the device, edge, and protocol layer. If your goal is visualization and analysis of the data, our Data Platforms are the right place. If you are looking for the operation of a ready IoT platform such as ThingsBoard or ChirpStack, the IoT product hub takes you further.
Visualization & analysis of the captured data
Predictive maintenance & anomaly AI on the data
Remote maintenance of the rolled-out device fleet
Operation of hosted IoT platforms
Open-source IoT platform, hosted in the EU
Sovereign LoRaWAN network server
We survey machine fleet, protocols, network, and compliance. Output: a clear connectivity concept with data model, edge architecture, and a binding fixed price - predictable instead of time and materials.
We build agents, protocol adapters, and pipeline and roll them out on a first machine or site. This lets you validate data quality, robustness, and security before the whole fleet follows.
Scaling to the entire fleet with device identities, update mechanism, and monitoring. Optional managed-operations contract or handover to your team with documentation and runbooks.
This page concerns the software right at the device and machine: edge agents, protocol gateways (OPC-UA, Modbus, MQTT), and secure connectivity. The visualization and analysis of the captured data is handled by our Data Platforms. The operation of a ready IoT platform such as ThingsBoard or ChirpStack lives in the IoT product hub. We often combine all three layers in one project.
On the industrial side primarily OPC-UA, Modbus (TCP/RTU), and MQTT, plus S7 communication, Profinet and Profibus bridges, BACnet for buildings, and LoRaWAN for radio sensors. Where a device only speaks a proprietary or undocumented protocol, we analyze the interface and encapsulate it in an edge adapter.
Yes. We run inference for anomaly detection, pre-classification, or image analysis directly on the edge device, so machine data does not have to leave the site and decisions are made without cloud latency. Training and larger AI features we couple with our AI software development.
The edge component runs on your hardware on site - industrial PC, gateway, or existing controller. The cloud side we operate on your infrastructure or in European data centers (Hetzner, IONOS, OVHcloud, STACKIT), GDPR compliant and without dependence on US hyperscalers. The stack is based on open-source components.
Devices receive their own identities and certificates, communication runs TLS-encrypted, and we separate OT and IT networks via defined transitions instead of flat connections. Access is logged. This meets the requirements of NIS2 and common critical-infrastructure rules.
We start with a discovery workshop that clarifies machine fleet, protocols, network, and compliance. On that basis you receive a binding fixed price - predictable instead of time and materials. We agree the concrete scope individually with you.
No risk: worst case, you leave with a clearer understanding of your project than before.

“With Timo and Robin, you're not only on the safe side technically - you also get the best human support! Whether it's quick help in everyday life or complex IT solutions: the guys from WZ-IT think along with you, act quickly and speak a language you understand. The collaboration is uncomplicated, reliable and always on an equal footing. That makes IT fun - and above all: it works! Big thank you to the team! (translated)”

“I recently worked with Timo and the WZ-IT team, and honestly, it turned out to be one of the best tech decisions I have made for my business. Right from the start, Timo took the time to walk me through every step in a simple and calm way. No matter how many questions I had, he never rushed me. The results speak for themselves. With WZ-IT, we reduced our monthly expenses from $1,300 down to $250. This was a huge win for us.”

“WZ-IT provided very competent support in implementing our server and virtualization infrastructure. As part of the project, a Proxmox-based virtualization environment was set up along with a virtual machine for our application systems. Additionally, a structured backup concept was implemented. A particular focus was on security: the setup of a VPN tunnel and the clean implementation of encryption and access concepts were professionally executed. The structured consulting as well as the reliable and swift implementation deserve special mention. We are very satisfied with the services provided and are happy to recommend WZ-IT.”
