IoT Infrastructure & Software.For the Westphalian Metropolis.
From Dortmund's port to the technology park: We connect Westphalia's logistics and service hub. Robust LoRaWAN networks and custom IoT apps for forward-thinking companies.
From Steel to Smart City.
Dortmund has mastered transformation like few other cities. Where blast furnaces once glowed (Phoenix West), technology centers now stand. Where coal was loaded, Europe's largest canal port and logistics hub now operates. merkaio delivers the digital infrastructure for this new middle class. We understand that WiFi often doesn't reach every corner of a modern logistics hall - and why you still need data from there.
Our team on the road in the Ruhr area
On-Site
We're quickly at your location - whether at the port, Phoenix West or the technology park.
Logistics Focus
We understand the requirements of freight forwarders, warehouses and port operations.
Tech Expertise
From sensor to API - we build end-to-end IoT solutions.
Our Service Portfolio for Dortmund.
Smart Logistics & Tracking
We make material flows transparent. Asset tracking on company premises or fill level monitoring in silos - wireless and without expensive cabling in large halls.
Custom IoT Development
Standard dashboards often aren't enough. Through merkaio dev, we build your logistics platform or driver app. We integrate sensor data directly into your dispatch software.
Managed LoRaWAN
We build and operate private wireless networks on your campus. GDPR-compliant, secure and independent of mobile contracts. Ideal for large areas like the port or Phoenix West.
Solutions for Dortmund.
How we can support local key industries:
Smart Port
Efficiency is the currency at the port.
Monitoring of truck parking spaces, container tracking and water levels. Robust outdoor sensors that work even in fog and industrial conditions. Real-time status of available loading docks directly on the dispatcher's tablet.
Milesight EM400 Outdoor Sensors.
Smart Building
Modern employers need modern spaces.
Flexible use of meeting rooms and open spaces. Anonymous people counting and CO2 measurement for ventilation and cleaning control. We integrate the data directly into Microsoft 365 or your room booking app.
People Counters & Room Climate Sensors.
Industrial Energy Management
Production meets climate protection.
Transparency about electricity and gas consumption in manufacturing (ISO 50001). Retrofit of existing meters using pulse and Modbus converters via LoRaWAN. Data lands automatically in the energy dashboard.
Current Transformers & Modbus Integration.
Technology for Concrete and Steel.
In the sprawling halls of Dortmund's logistics companies, WiFi reaches its limits. That's why we use LoRaWAN. This radio technology penetrates thick concrete walls and bridges distances of several kilometers across the port area.
Combined with our IP67 hardware (waterproof, dustproof) and open-source software, we build systems that are as robust as the region itself. No license traps, full data sovereignty.
