From LoRaWAN network planning to hardware selection and managed IoT hosting – your IoT service provider for Dortmund's logistics and technology hub. GDPR-compliant, personal, on-site.
Dortmund is one of Germany's most important logistics and technology hubs. With the Dortmund Port, the Technology Park, and numerous Industry 4.0 companies, new requirements for connected infrastructure arise here every day. We operate the IoT platforms that enable this connectivity – reliably, scalably, and GDPR-compliantly hosted.
Your IoT stack runs on GDPR-compliant servers in Germany. No US cloud, full data sovereignty for Dortmund-based companies.
Proactive monitoring of all IoT services with automatic alerts. Guaranteed response times via SLA – including nights and weekends.
No ticket system, no call center. Your direct line to the engineer managing your IoT instance in Dortmund.
ChirpStack, ThingsBoard, and Grafana on hardened infrastructure. Including automatic backups, security updates, and availability guarantees for Dortmund-based companies.
Complete LoRaWAN network deployment in Dortmund: hardware selection (Milesight gateways & sensors), radio coverage analysis, on-site gateway installation, and network server configuration. From planning to commissioning – all from one source.
End-to-end development of your IoT solution: custom web apps, mobile apps, Grafana and ThingsBoard dashboards. From data visualization to alerting logic – individually developed for Dortmund-based companies.
Hosting IoT platforms for real-time container tracking, temperature monitoring in cold chains, and yard management. We operate the server infrastructure that connects your logistics sensors.

Themen
We cover the entire process: requirements analysis, conception, platform architecture design, hardware selection, on-site LoRaWAN network deployment, platform development (web apps, mobile apps, dashboards), and ongoing managed operations. Everything from a single source.
We start with an initial consultation and requirements analysis. This is followed by architecture design, hardware selection, radio coverage analysis, gateway installation, platform development, app development, and go-live. Afterwards, we operate and monitor the entire infrastructure.
Yes. We advise on IoT architecture, platform selection, network planning, and hardware evaluation – even without subsequent implementation by us. Many clients start with consulting and then commission the implementation.
We primarily work with Milesight gateways and sensors – proven, CE-certified, and with excellent value for money. Depending on requirements, we also integrate other LoRaWAN hardware or sensors with MQTT, HTTP, or Modbus interfaces.
Yes. We create a radio coverage analysis upfront and plan the gateway positioning for the specific site – including consideration of buildings, metal structures, and interference sources in Dortmund's port and industrial areas.
Yes. We deliver all sensors and gateways with pre-set network parameters, payload decoders, and firmware updates. The devices are ready to use immediately and tuned to your platform.
Yes. Beyond standard dashboards with Grafana and ThingsBoard, we develop custom web apps and mobile apps for specific use cases – such as logistics tracking portals, production cockpits, or facility management apps.
Our core stack: ChirpStack as LoRaWAN network server, ThingsBoard (Community & Professional Edition) for device management, Grafana for visualization, and Node-RED for data flow automation. Custom apps are built with React, Next.js, and React Native.
Yes. Via REST APIs, MQTT, webhooks, and OPC-UA, we integrate IoT data into existing ERP, MES, and inventory management systems. Interface development is part of our standard service scope.
On GDPR-compliant infrastructure in German data centers. Alternatively, we set up the platform on-premise in your Dortmund data center.
We offer SLA tiers with availability guarantees up to 99.9%. Redundant infrastructure, automatic failover, and 24/7 monitoring ensure continuous operation.
Yes. We install and harden IoT platforms directly in your Dortmund server room – including VPN connectivity for remote maintenance and proactive monitoring.
A standard installation is production-ready within a few days. For complex projects with custom development and multiple locations, we create a joint rollout plan.
No. Our managed hosting services are cancellable monthly. We rely on quality and long-term collaboration rather than contract lock-in.
Yes. We design and develop multi-tenant platforms for multiple locations in the Dortmund area and beyond – with location-specific dashboards, access controls, and custom alerting logic.
