Connect a Unity scene to an MQTT broker with MQTTnet, animate a pump from live telemetry on the main thread, publish start and stop commands back to the device and move to TLS for production.
A practical comparison of open-source digital twin tools across modeling, data, visualization and history, with notes on how each one connects to an MQTT broker and when to combine them.
Component, asset, system and process twins differ in scope, data rate and the questions they answer. See examples of each and the MQTT topic and payload design that fits every level.
A practical guide to the digital twin in manufacturing, covering product, process and production twins, high-value use cases and a step-by-step plan to build the MQTT data foundation.
A practical guide to the mapping layer of a digital twin: how to bind IoT data to a 3D model by mapping MQTT topic values to glTF nodes, materials, morph targets and animation clips, with bindings stored in the model itself.
A practical six-level digital twin maturity model, with the capabilities, data infrastructure and MQTT patterns each level requires, plus a self-assessment to plan your next step.
A practical introduction to DTDL, the Digital Twin Definition Language: how interfaces, telemetry, properties, commands, components and relationships work, and how to map them to MQTT topics on a broker.
A simulation explores what could happen; a digital twin tracks what is happening. Learn the practical differences, how live MQTT data turns a model into a twin, and how the two work best together.
Why MQTT is the natural transport for digital twins, and how to design topics, retained state, presence and commands so a twin stays in sync with real assets, with runnable Python and JavaScript.
How to create a building digital twin that links BIM geometry with live HVAC, occupancy and energy data streamed over MQTT, with topic design, code and a rollout checklist.
How to build a warehouse digital twin that tracks inventory movement, AGVs and conveyor states in a live 3D model fed by MQTT topics, with topic design, code and pitfalls.
How to keep a digital twin and its physical asset in sync: reported and desired state, version numbers, conflict handling, reconnect recovery and retained MQTT topics, with a working Python device.
Build a lightweight digital twin where every property is a retained MQTT topic. Viewers get full twin state the instant they subscribe, with no database. Includes a Python simulator, a Node.js viewer and cleanup commands.
How fast does a real-time digital twin need to be? Latency budgets for visualization, monitoring and control twins, where the milliseconds go, how MQTT QoS and broker placement affect them, and a script to measure your own.
A hands-on Eclipse Ditto MQTT tutorial: run Ditto with Docker, create a thing, add an MQTT 5 connection to a broker, map device JSON into features and publish twin change events back to MQTT.
How city digital twins combine a geographic model with live traffic, street lighting and environmental sensor data published over MQTT, including topic design, code and a pilot checklist.
A step-by-step guide to a production-style web based 3D digital twin: model preparation, a Vite project, configuration-driven MQTT bindings, click-to-inspect details, connection health and static deployment.
Build an interactive Babylon.js digital twin of a cooling skid that reads live MQTT telemetry over secure WebSocket, highlights alarms, moves a gauge needle and sends start and stop commands when you click the pump.
How to model a site's energy flows as a digital twin fed by meters streaming over MQTT, then use it to find waste and test efficiency scenarios before spending money.
The difference between a digital model, a digital shadow and a digital twin comes down to which way data flows. See each level mapped to concrete MQTT telemetry and command topics.
Build a web digital twin dashboard where a Three.js scene, KPI cards, a trend chart and an alarm list share one MQTT connection and one state store, with click-to-focus navigation and stale-data handling.
A practical seven-step process for building your first digital twin: scope it, model the asset, design MQTT topics, stream live data, secure the broker, visualize it and add history.
Azure Digital Twins is not the only way to model connected assets. Compare open-source platforms and lightweight stacks built on standard MQTT, and see how to model a twin graph without platform lock-in.
