IoT platforms do not have to run in a vendor cloud and do not have to be billed per device. We build and run sovereign, self-hosted IoT stacks on open-source foundations - ThingsBoard, ChirpStack, LoRaWAN, MQTT, Node-RED and Grafana - on your own infrastructure (Proxmox, Hetzner, on-prem). Here we explain the fundamentals, the real costs instead of per-device licences, and the setup step by step.
What is LoRaWAN?
LoRaWAN is an open LPWAN radio standard for IoT: long range, years of battery life, AES encryption. Architecture, device classes and EU868 explained.
What is MQTT?
MQTT is the lightweight publish/subscribe protocol for IoT: brokers, topics, QoS levels, MQTT 5.0 and TLS security, explained clearly by WZ-IT.
What is ThingsBoard?
ThingsBoard is the open-source IoT platform for device management, telemetry, rule engine and dashboards. Editions, architecture and protocols explained.
What is ChirpStack?
ChirpStack is an open-source LoRaWAN Network Server under the MIT license. We explain its components, supported gateways and self-hosted operation, no lock-in.
IoT architecture in layers
IoT architecture explained layer by layer: from sensors over LoRaWAN/MQTT, gateway and ThingsBoard to InfluxDB and Grafana - fully self-hosted and open source.
LoRaWAN vs NB-IoT vs WLAN/5G
LoRaWAN, NB-IoT, LTE-M or 5G for IoT? Compare range, battery life, data rate, cost and who owns the network - plus the self-hosted LoRaWAN angle.
ThingsBoard pricing & editions
ThingsBoard pricing 2026: Community Edition is free, Professional Edition from $10/month, Cloud charges per device. Honest self-hosted vs cloud TCO.
How much does ChirpStack cost?
How much does ChirpStack cost? It is open source and free (MIT). The real costs: servers, gateways, operations and maintenance - honest LoRaWAN TCO inside.
ThingsBoard vs ChirpStack
ThingsBoard vs ChirpStack: they do not compete. ChirpStack is the LoRaWAN Network Server, ThingsBoard the IoT platform. Here is how they complement each other.
IoT platform: self-hosted vs cloud
Self-hosted IoT vs. cloud: data sovereignty, GDPR, real costs and lock-in compared. ThingsBoard/ChirpStack vs. AWS IoT, Azure IoT, Cumulocity.
Open-source IoT platforms compared
ThingsBoard vs Node-RED vs EdgeX Foundry vs Eclipse Ditto vs OpenRemote: purpose, device management, dashboards, rules, licensing and self-hosting compared.
ThingsBoard vs AWS IoT Core & Azure IoT Hub
ThingsBoard vs AWS IoT Core and Azure IoT Hub 2026: features, current pricing with a worked example, GDPR and lock-in - self-hosted or hyperscaler?
Install ThingsBoard with Docker
Install ThingsBoard CE with Docker: step-by-step docker-compose guide with PostgreSQL, ports, first login, demo account, device and dashboard.
Set up ChirpStack & a LoRaWAN gateway
Install ChirpStack with Docker, register a LoRaWAN gateway, add an OTAA device and read sensor data via MQTT. Self-hosted step-by-step guide.
Grafana IoT dashboard with InfluxDB
Self-hosted Grafana IoT dashboard with InfluxDB: install InfluxDB, ingest IoT data via MQTT/Telegraf or ThingsBoard, add the data source, panels and alerts.
ThingsBoard Rule Engine: alarms & notifications
ThingsBoard Rule Engine setup: threshold alarms, severity and notifications via email, Slack and webhook - with an example rule chain and test.
Milesight sensor in ChirpStack: payload decoder
Decode a Milesight LoRaWAN sensor in ChirpStack: grab the official JavaScript decoder from GitHub and add it to the device profile as a payload codec.
Node-RED MQTT dashboard for sensor data
Node-RED MQTT dashboard step by step: install Node-RED 5 with Docker, set up Dashboard 2.0, parse a JSON payload and show live sensor data as a gauge and chart.
Predictive maintenance & retrofit
Retrofit legacy machines without a modern interface using sensors, an edge gateway and OPC-UA/Modbus, then analyse it in ThingsBoard and Grafana - self-hosted.
Building IoT / smart building with LoRaWAN
Smart building IoT with LoRaWAN: monitor occupancy, CO2, energy and leaks with one gateway per building - self-hosted on ChirpStack, ThingsBoard, Grafana.
WZ-IT builds and runs IoT in production for companies - design, build and operations from one team.
