ChirpStack

ChirpStack Development & Integration

Custom extensions, API integrations, and seamless embedding into your system landscape.

Standard software often covers 90% – we close the last gap. We develop Payload Codecs, connect ChirpStack with your tools, and automate workflows.

Development Services

Our Development Services

From API integration to complete custom solutions – we cover the entire spectrum.

API & Interface Integration

We make your systems talk to each other. Whether REST, GraphQL, or webhooks – we connect software with your CRM, ERP, or identity provider.

  • Bidirectional data synchronization
  • Third-party system connections
  • Custom webhooks & event handlers
  • Legacy system integrations

Custom Middleware & Logic

Often data formats from System A don't match System B. We develop middleware that sits in between, transforms data, and controls processes.

  • Transformation layer (ETL)
  • Data stream validation
  • Caching layer for performance
  • Microservices architecture

Embeddings & Custom Apps

Want to use software features in your own intranet or customer portal? We embed software headlessly and build custom UIs around it.

  • White-label integration
  • Custom dashboards (React/Vue)
  • UI extension via plugins
  • Mobile app customizations

Automation & Bots

Save manual work through intelligent automation. We develop bots and scripts that handle tasks automatically.

  • ChatOps & slash commands
  • Automated reporting
  • Workflow orchestration
  • Trigger-based actions
Architecture & Interfaces

LoRaWAN Data Engineering

ChirpStack is the heart of your LoRaWAN network. The challenge lies in the data: sensors send hex bytes, your app needs JSON. We close this gap.

Payload Codecs (JavaScript)

The most important dev part: We write decoder functions for your specific sensors (Milesight, Adeunis, Custom). We convert `0x012F` to `{ temperature: 22.5, unit: 'C' }` – directly in the Network Server.

MQTT & HTTP Integrations

Data must flow. We configure and develop bridges that send decoded data via MQTT to your broker or push it via HTTP webhook into your business application.

Downlink Logic

IoT is not a one-way street. We develop logic that sends commands BACK to the sensor based on analysis (e.g., 'Close Valve' or 'Change Reporting Interval').

Practical Examples

Concrete Use Cases

How we implement ChirpStack development in practice.

Proprietary Sensor Decoders

Problem

You use specialized sensors or in-house developments for which there is no standard profile in ChirpStack.

Solution

Reverse engineering of the byte payload and development of an efficient JavaScript codec according to manufacturer specifications.

Time-Series Bridge (InfluxDB)

Problem

Sensor data should be stored for long-term analysis, but ChirpStack only stores short-term.

Solution

A Go/Python service that listens to the MQTT stream and writes optimized data to InfluxDB or TimescaleDB – ready for Grafana.

Smart Alerting

Problem

Alarm on threshold violation, but please not with every single packet (debouncing).

Solution

Middleware logic that analyzes the data stream and only alerts if a value remains critical for X minutes (hysteresis).

Why WZ-IT

Development with Foresight

Update-safe, scalable, and secure – why you should trust us with your development.

Update-safe (No Core Hacking)

We don't modify the open-source software's source code. Instead, we use official APIs and plugin architectures. Your installation remains updatable and maintainable.

Full-Stack Expertise

We understand not just the code, but the infrastructure beneath it. Our developers know how queries affect database performance and how to build scalable APIs.

Modern Tech Stack

We use modern, type-safe technologies: React, TypeScript, Node.js, Python, Go. Plus PostgreSQL, Redis, and Docker/Kubernetes for infrastructure.

Security by Design

Every line of code is written with security in mind. Input sanitization, secure authentication (OAuth2/OIDC), and compliance with data protection regulations are standard.

"I recently worked with Timo and the WZ-IT team, and honestly, it turned out to be one of the best tech decisions I have made for my business. Right from the start, Timo took the time to walk me through every step in a simple and calm way. No matter how many questions I had, he never rushed me. The results speak for themselves. With WZ-IT, we reduced our monthly expenses from $1,300 down to $250. This was a huge win for us."

"Counting on WZ-IT team was crucial, their expertise and solutions gave us the pace to deploy in production our services, even suggesting and performing improvements over our configuration and setup. We expect to keep counting on them for continuous maintenance of our services and implementation of new solutions."
"

Timo and Robin from WZ-IT set up a RocketChat server for us - and I couldn't be more satisfied! From the initial consultation to the final implementation, everything was absolutely professional, efficient, and to my complete satisfaction. I particularly appreciate the clear communication, transparent pricing, and the comprehensive expertise that both bring to the table. Even after the setup, they take care of the maintenance, which frees up my time enormously and allows me to focus on other important areas of my business - with the good feeling that our IT is in the best hands. I can recommend WZ-IT without reservation and look forward to continuing our collaboration! (translated)

"

We have had very good experiences with Mr. Wevelsiep and WZ-IT. The consultation was professional, clearly understandable, and at fair prices. The team not only implemented our requirements but also thought along and proactively. Instead of just processing individual tasks, they provided us with well-founded explanations that strengthened our own understanding. WZ-IT took a lot of pressure off us with their structured approach - that was exactly what we needed and is the reason why we keep coming back. (translated)
