Our Services
Digitalization that delivers - from concept to operation.
IoT Platforms & Portals
Digital products instead of data silos
Custom IoT platforms and customer portals that turn sensor data into real value. Multi-tenant, white-label ready, and scalable.
Mobile Apps
Your data, everywhere
Native iOS and Android apps for field technicians or end users. Offline-capable, with push notifications and real-time data.
Interfaces & Integrations
No more island solutions
We connect your IoT infrastructure with existing systems - ERP, inventory management, BI tools, or cloud services.
IoT Infrastructure
From sensor to cloud
The complete IoT solution from a single source: network planning, installation, platform operation, and long-term support. GDPR compliant.
Hardware Consulting
The right technology for your use case
Selection and procurement of sensors, gateways, and connectivity. Pre-configured, tested, vendor-independent.
Data Analysis & Reporting
Data becomes decisions
Dashboards, reports, and alerts that make sense. Data-driven decisions instead of gut feeling.
Powered by the merkaio Stack
The merkaio Stack
A modular offering built around one unified foundation.
merkaio core
The unified IoT foundation
A standardized, proven IoT technology stack - from devices to dashboards.
One stack. Fully understood. Fully operable.
merkaio ops
Operated IoT platforms
We operate the complete merkaio stack as a managed service.
You don't run the stack. We do.
merkaio cloud
Cloud foundation for IoT workloads
The secure and scalable infrastructure layer for IoT operations.
Cloud-native by design. Built for IoT realities.
merkaio dev
Custom extensions & integrations
When standard components are not enough, merkaio dev extends the stack - from decoders to complete IoT apps.
We extend the stack - we don't reinvent it.
Hardware Expertise with Milesight
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.
Browse all Milesight devicesWe also work with hardware from other manufacturers such as Dragino, RAKwireless or Teltonika, whether proprietary or open-source. What matters is that it works reliably and integrates into our stack.
We break the pattern.
Why pay for software that's actually free?
Many IoT platforms are built on open-source technology like ThingsBoard or Grafana without disclosing it. We believe in transparency and play with open cards.
The Market Standard
The Trap- White-LabelingOpen-source software is sold as proprietary invention.
- License CostsYou pay high monthly fees per device for software that's actually license-free.
- Vendor Lock-inYour data and configurations are trapped in a "blackbox". Switching is nearly impossible.
- OpacityYou don't know what your business runs on.
The merkaio Way
The Solution- 100% TransparencyWe tell you exactly what we use (ChirpStack, ThingsBoard, Grafana).
- No License FeesYou pay for our work (setup, operations, security), not for the code.
- Full OwnershipThe stack belongs to you. You have full access to databases and admin panels.
- FreedomSince we use standards, you can theoretically take over operations yourself or switch providers at any time.
We don't hide behind licenses. We convince through operations.

About merkaio
IoT infrastructure that belongs to the company - open, sovereign, built to last.
Timo Wevelsiep
Founder
The idea behind merkaio: companies should own and control their IoT infrastructure themselves. An open-source stack, open standards and direct technical advisory - so data, configuration and cost stay in the customer's hands for the long run.
Timo Wevelsiep is also managing director at WZ-IT - an IT services company from the Ruhr area that helps companies from startup to enterprise worldwide build sovereign cloud infrastructure. GDPR-compliant, open-source-first and operated in Europe.

Client testimonial
Timo took our IoT requirements and turned them into a clean, white-labeled monitoring platform that just works. What stood out was that he built it to grow with us: each new customer and site slots into the same structure, so onboarding is fast and we're not redesigning dashboards or data flows every time. The foundation lets us expand without rethinking how the platform is put together. Highly recommended for serious IoT projects.
