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.

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.

Services by Division

merkaio core

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.

A valid blueprint that works.

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.

A system that runs reliably - operated by you or by us.
merkaio cloud

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.

A secure, scalable runtime environment.
merkaio dev

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 platforms and mobile apps for your sensor data (React, Vue, ThingsBoard).

Data that is usable, integrated, and visible.
Milesight

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.

How our divisions work together in a project:

01

Design

We select hardware and architecture.

core
02

Deploy

We set up the servers and networks.

cloud
03

Integrate

We connect data streams and build dashboards.

dev
04

Stabilize

We set up monitoring and take over operations - or hand over to your team.

FAQ - Engineering & Services

Yes. We also take on isolated project assignments, such as architecture concepts, hardware evaluations, or developing specific payload decoders. Many customers start with an engineering project (e.g., a PoC) to validate technical feasibility before committing to ongoing operations (Managed Hosting).
No. While we specialize in Milesight hardware because it integrates seamlessly into our merkaio core and we have deep expertise, our architecture is based on open standards (LoRaWAN, MQTT). We can technically integrate any hardware that properly implements these protocols (e.g., Kerlink, Dragino, Tektelic). We advise you neutrally on which hardware best suits your use case.
Yes, this is a classic "brownfield" scenario. Our Migration Services (part of merkaio cloud) are designed exactly for this. We audit your existing stack (e.g., self-hosted ChirpStack or TTN), identify bottlenecks, and migrate configuration and data into a clean, scalable merkaio architecture.
The code belongs to you. Our philosophy is "No Vendor Lock-in". Everything we develop individually for you in the merkaio dev area (dashboards, scripts, decoders), we hand over to you with full usage rights. Since we primarily use open-source technologies, you can theoretically run the stack we built yourself or with another provider at any time.
Yes. Within merkaio dev, we build custom IoT web applications and mobile apps. Our focus is strictly on data-driven solutions: We build dashboards, customer portals, or control apps that seamlessly integrate with the merkaio infrastructure. We use modern frameworks (like React, Vue, Node.js) or ThingsBoard's app features to make your sensor data user-friendly and accessible.
We offer two models: Fixed price for clearly defined packages like "Payload Decoder Development", "Gateway Pre-configuration", or standardized "PoC Setups". Time & Material for complex architecture consulting, custom development, or troubleshooting - transparently billed at daily rates.
Since we rely on a standardized stack (merkaio core), we're significantly faster than traditional custom developers. A typical PoC - from hardware ordering to cloud setup to the first dashboard - is often achievable within 2 to 4 weeks, provided the hardware is available.
Our focus is remote engineering, cloud, and pre-staging (pre-configuration). We deliver hardware "Plug & Play" ready to you or your installers. For physical mounting on buildings or masts, we typically work with your local electricians or facility teams, whom we guide via remote support and documentation.

Let's discuss your infrastructure. Digital and on-site.

Whether it's IoT platform development, hardware selection, managed hosting for ChirpStack, ThingsBoard, Grafana or NetBird VPN, or migration from a self-hosted setup - we'll find the right solution for your use case. Book a free 30-minute consultation, no commitment required.
