IoT Engineering Services.
Built on the merkaio stack.
We support companies with architecture, hardware sourcing and system integration. Our services follow a clear structure: We use the building blocks Core, Cloud and Dev to build tailored solutions that are Ops-ready.
Engineering, not consulting slides.
IoT projects often fail due to complexity. We solve this not through theoretical consulting, but through engineering along our proven stack. Every service package is directly assigned to one of our divisions – ensuring that everything we build can be operated reliably later.
Services by Division
Foundation & Hardware Engineering
We define the foundation of your IoT project.
- IoT Architecture Design
Selection of the right topology (LoRaWAN, MQTT, gateway placement).
- Hardware Sourcing
As hardware experts, we don't just advise – we source and validate sensors and gateways.
- Connectivity Planning
Network coverage planning and selection of transmission paths.
- Proof of Concept (PoC)
Building a validated minimal stack for testing.
Operations Setup & Managed Service
The final step of engineering is preparing for continuous operation – or we take over operations completely as a managed service with SLAs.
- Monitoring Setup
Setting up Prometheus exporters and alert rules.
- Disaster Recovery Planning
Setting up and testing backup routines.
- Documentation
Technical documentation of the built stack.
- Managed Service / Handover
Clean handover to managed service or to your internal team.
Infrastructure Setup & Provisioning
We build the environment where your data lives.
- Cloud Architecture
Design of the server landscape (Hetzner, AWS, Private Cloud).
- VPN & Network Setup
Setting up secure tunnels between gateways and cloud (WireGuard/OpenVPN).
- Security Audit
Hardening existing systems and setting up firewalls/IAM.
- Migration Services
Moving legacy systems (e.g. TTN or V2 stacks) to a clean merkaio environment.
Custom Development & Integration
We close the gaps between standard tools and build data-driven applications.
- Payload Decoder
Development of complex JS decoders for industrial sensors/controllers.
- Middleware & APIs
Scripts (Node.js/Python) for data transformation or forwarding to ERP/SAP.
- Dashboard Development
Building complex Grafana panels or ThingsBoard rule chains beyond standard configs.
- IoT Apps & Portals
Custom web apps and mobile apps for your sensor data (React, Vue, ThingsBoard).
Hardware expertise that understands the stack.
Software is nothing without the right hardware. We specialize in the Milesight ecosystem and seamlessly integrate gateways and sensors into the merkaio core.
- Pre-Staging
We configure devices before shipping. Unpack, power on, online.
- Firmware Management
We validate firmware versions against our stack.
- Sensor Consulting
We find the right sensor for temperature, fill level or people counting.

The "Build to Operate" Flow
How our divisions work together in a project:
Design
We select hardware and architecture.
coreDeploy
We set up the servers and networks.
cloudIntegrate
We connect data streams and build dashboards.
devStabilize
We set up monitoring and take over operations – or hand over to your team.
opsFAQ – Engineering & Services
Engineering for the real world.
Let us design and build your stack – ready for operation.
