Architecture & Interfaces
ChirpStack Development & Integration
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').
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).
Infrastructure, integration and operations
ChirpStack as part of your infrastructure
We do more than provide an application. WZ-IT designs the technical architecture, integrates network and identity, operates the agreed scope and develops integrations when the standard product is not enough.
Network and identity
SSO, secure access, internal systems and existing security components are integrated appropriately.
Monitoring and service level
Updates, backups, technical monitoring and response paths follow a transparent operational scope.
Integration and development
APIs, automation and custom extensions can be delivered beyond basic deployment.
The exact scope depends on the application, edition, infrastructure and criticality. Vendor licences and non-standard components are quoted separately.
Target architecture
Integrate ChirpStack into your infrastructure with clear controls
IoT platforms connect devices, gateways, message transport, time-series data and business systems through controlled network and data paths.
Devices, gateways and sites
Sensors, equipment and edge components send telemetry and receive approved control information.
Secure access
TLS, firewall rules, reverse proxies or private network paths are designed around the platform's exposure.
Identity and permissions
Local accounts, SSO, directories, service accounts and emergency access are connected through clear roles.
ChirpStack platform
Device management, rules, processing and tenants are operated for the fleet and data volume.
Brokers and protocols
MQTT, LoRaWAN, HTTP or further protocols with governed device identities.
Telemetry and storage
Time series, retention, aggregation, capacity and recovery.
Dashboards and business systems
Visualisation, alerting, APIs and integration into operational processes.
The diagram is a resilient target model. Its implementation depends on edition, data flows, load, availability objectives and existing infrastructure.

Frequently Asked Questions about ChirpStack
Everything about the LoRaWAN Network Server, operations and our services
Topics
Basics
ChirpStack is an open-source LoRaWAN® Network Server stack that allows you to connect, manage, and securely integrate LoRaWAN gateways and end devices into your systems - typically via MQTT/HTTP/API.
For IoT/IIoT such as sensors in buildings, industry, agriculture, smart city, tracking, and monitoring - anywhere long battery life and wide radio range are important (LoRaWAN).
Typically: Gateway Bridge, ChirpStack (Network Server + Web UI), and backend components (e.g., PostgreSQL, Redis, MQTT Broker).
In standard setups, ChirpStack uses PostgreSQL (persistence), Redis (caching/state), and an MQTT broker for messaging/integrations.
Gateways & Devices
The gateway is the radio bridge between your LoRaWAN end devices and the server stack. It forwards LoRaWAN frames to ChirpStack (and downlinks back).
Yes - we set up gateways, connect them to ChirpStack, and test the radio link (gateway ↔ device), including proper documentation and acceptance testing.
Basically: Create the gateway in ChirpStack, configure the forwarder/station, verify connectivity, and validate LoRaWAN frames.
All LoRaWAN-compatible sensors/trackers/modules, provided the region/parameters and activation (OTAA/ABP) match and the necessary identities/keys are available.
ChirpStack works with Device Profiles (capabilities/versions/region params) and Applications (logical grouping of devices by use case).
At minimum: DevEUI, LoRaWAN MAC version, and Regional Parameters Revision. For ABP, also DevAddr + session keys; for OTAA, root keys - unless using an external join server.
Yes. In practice, OTAA is usually standard (better key handling/provisioning), ABP is used depending on device/use case.
In ChirpStack, you can check LoRaWAN frames and device events (JoinRequest/JoinAccept, uplinks, etc.).
Yes: Device Profiles can reference a payload decode function to transform raw data into usable values.
Integrations & Data Flows
Typically via MQTT (events/topics), alternatively via APIs/integrations. MQTT is a central integration pattern in ChirpStack.
Yes - we set up the MQTT broker properly (TLS, credentials, permissions/topics), connect ChirpStack, and provide clear documentation of data flows.
ChirpStack publishes events like Uplink, Join, etc. - and tools like Node-RED can subscribe to and process these events.
Yes - e.g., forwarding to databases/time series, dashboards, alerting, or to your business systems. Common components: Node-RED, workers/streams, TSDB, data lake.
Infrastructure & Scaling
Yes. ChirpStack is suitable for self-hosted setups - on-prem or in a private/isolated cloud environment, including controlled network segments and data flows.
Yes - we plan and build secure connectivity (e.g., VPN/S2S, segmented networks, firewall rules) so gateways reliably and securely communicate with ChirpStack.
Yes - depending on architecture/provider/network design (e.g., multiple gateway locations, central processing, separate environments).
Scaling typically happens through: broker/DB performance, horizontal components, clean topic structure, backpressure, and capacity planning.
Operations & Security
They prevent chaos: Profiles bundle LoRaWAN version/region parameters/activation/decoder and ensure device groups remain consistent and operable.
Classics: wrong DevEUI/keys (MIC errors), wrong region/parameters, gateway config, frame counter issues.
Via metrics/logs from components (ChirpStack, DB, Redis, broker) and infrastructure monitoring. Goal: detect drops/backlogs early before uplinks disappear.
Yes - especially for PostgreSQL (configuration/state), plus robust backup strategy and regular restore checks.
Yes - in the sense that you can operate, integrate, and secure it in a controlled self-hosted manner. Enterprise primarily comes from the operational concept (monitoring, backups, updates, documentation, SLAs).
TLS wherever possible, least privilege, separate service accounts, network segmentation, secrets handling, update policy, logging/auditing, and documented data flows.
Yes - we handle operations, updates, monitoring, backups, incident response, and performance tuning as managed hosting / managed operations.
WZ-IT Services
Typically: ChirpStack stack setup (infrastructure + services), gateway rollout (config, site check, tests), private networks/VPN, sensor onboarding, MQTT broker + integration pipelines, data processing (DB/TSDB/dashboards/alerts).
Usually in 5 steps: 1. Requirements (region, use case, device types, data targets), 2. Architecture & security baseline, 3. Stack setup + MQTT + monitoring/backups, 4. Gateway + device pilot (1-3 device types), validation, 5. Rollout + operations (SLA/runbooks/documentation). More details on our ChirpStack page.

The structured consulting as well as the reliable and swift implementation deserve special mention. We are very satisfied with the services provided and are happy to recommend WZ-IT.”

“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)”

“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)”
