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 Gelsenkirchen.
ChirpStack, ThingsBoard, and Grafana on hardened infrastructure. Including automatic backups, security updates, and availability guarantees for Gelsenkirchen-based companies in the solar, chemical, and industrial sectors.
Complete LoRaWAN network deployment in Gelsenkirchen: hardware selection (Milesight gateways & sensors), radio coverage analysis for solar parks, chemical plants, and urban areas, 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 real-time solar yield visualization to chemical plant alerting logic – individually developed for Gelsenkirchen-based companies.
Hosting IoT platforms for real-time monitoring of inverters, solar yields, module temperatures, and grid feed-in power. We operate the server infrastructure connecting your photovoltaic systems and energy parks across Gelsenkirchen, Germany's solar city.

Themen
We operate monitoring platforms for photovoltaic systems and energy parks: real-time capture of inverter data, solar yields, module temperatures, and grid feed-in power. Including automated alerting for performance drops or malfunctions.
Yes. Through continuous monitoring of module temperature, shading, and inverter performance, we identify power losses early. This enables faster maintenance cycles and maximizes energy yield.
Yes. Beyond solar monitoring, we build IoT platforms for wind turbines, heat pumps, and battery storage systems. The platform aggregates all energy sources into a single centralized dashboard.
We integrate vibration sensors, temperature probes, gas detectors, and pressure transmitters. Depending on requirements, we use LoRaWAN sensors, ATEX-certified devices, or wired sensors with Modbus interfaces.
Yes. We conduct a radio coverage analysis upfront and account for ATEX zones, metal structures, and interference sources in Gelsenkirchen's chemical parks and industrial sites. Where required, we deploy ATEX-certified hardware.
The IoT platform monitors defined thresholds for temperature, gas concentrations, and vibrations. When limits are exceeded, automatic notifications are sent via email, SMS, or webhook to the responsible teams.
IoT technology enables the digitalization of former industrial sites: from building automation at Nordsternpark to environmental monitoring on brownfield conversion areas. Connected sensors make the transformation measurable and manageable.
Yes. Beyond standard dashboards with Grafana and ThingsBoard, we develop custom web apps and mobile apps for specific use cases – such as energy management portals, plant monitoring cockpits, or facility management apps for Gelsenkirchen-based companies.
Yes. Via REST APIs, MQTT, webhooks, and OPC-UA, we integrate IoT data into existing ERP, SCADA, and process control systems. This is particularly relevant for Gelsenkirchen's chemical industry, where legacy systems need seamless integration.
On GDPR-compliant infrastructure in German data centers. Alternatively, we set up the platform on-premise in your Gelsenkirchen data center or server room.
We offer SLA tiers with availability guarantees up to 99.9%. Redundant infrastructure, automatic failover, and 24/7 monitoring ensure continuous operation – critical for safety-sensitive applications in the chemical industry.
Yes. We install and harden IoT platforms directly in your Gelsenkirchen server room – including VPN connectivity for remote maintenance and proactive monitoring. Ideal for chemical plants with heightened security requirements.
A standard installation is production-ready within a few days. For complex projects involving solar monitoring and chemical plant integration, 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 – from solar parks to chemical plants to municipal properties in Gelsenkirchen and across the Ruhr area. With location-specific dashboards, access controls, and custom alerting logic.
