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.
From API integration to complete custom solutions – we cover the entire spectrum.
We make your systems talk to each other. Whether REST, GraphQL, or webhooks – we connect software with your CRM, ERP, or identity provider.
Often data formats from System A don't match System B. We develop middleware that sits in between, transforms data, and controls processes.
Want to use software features in your own intranet or customer portal? We embed software headlessly and build custom UIs around it.
Save manual work through intelligent automation. We develop bots and scripts that handle tasks automatically.
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.
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.
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.
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').
How we implement ChirpStack development in practice.
You use specialized sensors or in-house developments for which there is no standard profile in ChirpStack.
Reverse engineering of the byte payload and development of an efficient JavaScript codec according to manufacturer specifications.
Sensor data should be stored for long-term analysis, but ChirpStack only stores short-term.
A Go/Python service that listens to the MQTT stream and writes optimized data to InfluxDB or TimescaleDB – ready for Grafana.
Alarm on threshold violation, but please not with every single packet (debouncing).
Middleware logic that analyzes the data stream and only alerts if a value remains critical for X minutes (hysteresis).
Update-safe, scalable, and secure – why you should trust us with your development.
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.
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.
We use modern, type-safe technologies: React, TypeScript, Node.js, Python, Go. Plus PostgreSQL, Redis, and Docker/Kubernetes for infrastructure.
Every line of code is written with security in mind. Input sanitization, secure authentication (OAuth2/OIDC), and compliance with data protection regulations are standard.
Our Tech Stack
From requirements to go-live – transparent and structured.
We review API documentation, analyze your requirements, and identify optimal integration points.
We design the solution: middleware, plugin, or script. Data flows, interfaces, and security concept are defined.
Agile implementation with code reviews, automated tests, and continuous coordination. You see progress in real-time.
Integration into your CI/CD pipeline or hosting on our infrastructure. Documentation and training included.
Let's get technical. We'll assess feasibility and effort.
