MQTT
MQTT (Message Queuing Telemetry Transport) is a lightweight publish/subscribe messaging protocol operating over TCP/IP. Developed by IBM and standardized by OASIS, it is designed for environments with limited bandwidth, unreliable networks, or constrained computational resources, featuring low overhead and low power consumption. MQTT is widely used for asynchronous message communication in the Internet of Things, embedded systems, and mobile devices.

Edge gateways take on responsibilities such as protocol conversion (e.g., converting Modbus or OPC UA to MQTT), local caching and store-and-forward during network outages, and data filtering and downsampling, and often run lightweight inference to enable local alerts at millisecond-to-second latency.
A typical AIoT technology stack includes edge computing nodes (low-latency inference on the device side), a cloud data platform (model training and long-term trend analysis) and device management protocols (such as MQTT and OPC UA).
After logging in, Postman supports more protocol types (such as gRPC and MQTT) and supports managing interface requests through directories; without logging in, it mainly supports the HTTP protocol.
In industrial scenarios, AIoT and IIoT overlap heavily: IIoT focuses more on the industrial protocol stack for device connectivity and data collection (such as OPC UA, Modbus, MQTT), while AIoT's focus is on using models such as machine learning and computer vision to turn data into judgments and decisions.
IoT protocols such as MQTT and CoAP generally lacked mandatory encryption mechanisms in their early designs.
Lamp's environmental data is accessible in read-only mode via Web and MQTT.
Playback runs on a K3S cluster on a local server, connects to local camera streams and an MQTT broker, and feeds data into a time-series database.
The second step of the solution is to fully replicate Roborock's backend technology stack, including the MQTT messaging channel and REST interface.
Roborock vacuum cleaners report cleaning status in real time, receive commands, and synchronize sensor data via the MQTT channel, while obtaining map data and updating device configuration via the REST interface.
Telemetry data is typically pushed periodically to a backend API via MQTT, HTTP, or proprietary protocols.
