Media infrastructure, chemical industry, logistics hub - Designed around documented data paths, clear operating responsibilities, and personal technical support.
Companies worldwide trust WZ-IT
Regional requirements, robust technology
Köln is the largest city in North Rhine-Westphalia and Germany's fourth largest - an economic powerhouse that combines media, chemical manufacturing, automotive production, and international logistics. With the Mediapark, chemical plants in Köln-Nord, the Ford factory in Niehl, and Köln/Bonn Airport as a major cargo hub, the demand for connected infrastructure is substantial and growing. We operate the IoT platforms that enable this connectivity - reliably, scalably, and hosted in Germany or the EU with documented privacy safeguards.
Sensors, gateways, data platform, business application, identities, interfaces, and operations are planned together. Additional sites, cloud services, or local edge systems can then build on the same architecture model.
Your IoT stack runs on privacy-focused servers in Germany. No US cloud, control over data location and access for Köln-based companies.
Automated 24/7 monitoring with alerts. Human response times and support coverage follow the selected service level; overnight P1 response is included with Production and Critical.
No ticket system, no call center. Your direct line to the engineer managing your IoT instance in Köln.
Concrete services
You can start with one clearly defined requirement. Architecture, devices, platform, applications, and operations are planned so the first component can become part of one coherent IoT system when needed.
ChirpStack, ThingsBoard, and Grafana on hardened infrastructure. Including automatic backups, security updates, and 24/7 monitoring for Köln-based companies - from media houses and chemical operators to logistics providers.
View serviceWe plan radio coverage and gateway positions from site and building data, select suitable gateways and sensors, provision devices and payload decoders, and integrate them with ChirpStack. Device onboarding, data validation, and radio testing are coordinated with the platform.

The examples illustrate possible application patterns. Architecture, radio coverage, device selection, data model, and operating scope are assessed for the specific project.
One system instead of isolated silos
Value does not come from a single sensor or dashboard. What matters is an end-to-end data path with clear interfaces, access rules, and operating responsibilities.
Sensors, gateways, machines, PLCs, and existing data sources are selected or connected according to the measurement task, environment, and protocol.
View componentLoRaWAN, MQTT, cellular links, edge gateways, and private networks move data between sites, platforms, and other systems in a controlled way.
View componentChirpStack, ThingsBoard, Grafana, databases, and rule engines provide device management, processing, history, and alerting.
View componentDashboards, portals, mobile apps, and ERP, MES, and API integrations put IoT data into the actual workflows.
View componentMonitoring, backups, updates, incident response, and service levels keep the platform and data paths maintainable and transparent.
View componentThe architecture can grow with more devices, sites, applications, and deployment locations without introducing isolated connections or hard-to-maintain special paths for every extension.
Technical foundation
We rely on a proven open-source stack: ChirpStack as LoRaWAN network server, ThingsBoard for device management and dashboards, Grafana for real-time visualization, and Node-RED for data routing. All hosted on hardened Linux servers with automatic backups and security updates.

Deployment models
We rely on Milesight and know the product portfolio inside out - from environmental sensors to LoRaWAN gateways to industrial controllers. We advise, source and integrate the right hardware for your use case.
Milesight hardware ships worldwide - we deliver pre-configured and firmware-updated, ready to deploy.
We also work with hardware from other manufacturers - whether proprietary or open-source. What matters is that it works reliably and integrates into our stack.
Project path
The initial step remains manageable. Device count, architecture, integrations, and operating responsibilities are defined only after the technical assessment.
Capture measurements, sites, users, existing systems, alert paths, and the expected business outcome.
Combine radio path, devices, platform, data model, interfaces, and security requirements in a testable design.
Provision devices, configure services, process data, and connect dashboards or business applications.
Agree monitoring, updates, backups, and response paths, then add further sites or capabilities in a controlled way.
Region and scale
A regional entry point does not limit the architecture. Platforms can cover multiple plants, properties, fields, or customer sites under one operating model.
The regional scope includes Köln, Hürth, Frechen, Leverkusen, Wesseling, Brühl. Multiple sites can share one platform while retaining separate roles, data spaces and alert paths.
Industries
The technical foundation can be adapted to different measurement tasks and business processes.
Specialist services
Dedicated service pages explain platforms, development, LoRaWAN, and visualization in detail.
Enquiry
Briefly describe the measurement task, sites, existing devices, and desired outcome. We will assess architecture, platform, integration, and possible operations.
