Open Source IoT Software

Zigbee2MQTT is an open-source bridge that lets users operate Zigbee devices without relying on proprietary vendor gateways. It connects compatible Zigbee adapters to devices and translates their events and controls into MQTT messages. This makes Zigbee hardware usable with a wide range of home automation platforms rather than tying it to one ecosystem. The project maintains device state locally and provides web interfaces for monitoring and configuration. Its architecture combines zigbee-herdsman for radio communication with device converters that map individual hardware models to Zigbee capabilities. It supports an extensive device catalog and integrates with platforms such as Home Assistant, Homey, Domoticz, Gladys Assistant, and ioBroker.

MQTT is a Chinese translation of the OASIS MQTT 3.1.1 protocol specification for developers working with messaging, machine-to-machine systems, and the Internet of Things. It explains MQTT as a lightweight client-server publish-and-subscribe transport designed for constrained devices and networks. The documentation covers protocol concepts, control packet formatting, operational behavior, security, WebSocket transport, and conformance requirements. Individual chapters describe connection, publication, subscription, acknowledgment, heartbeat, and disconnection packets in detail. The material can be read through GitBook, the repository wiki, HTML, PDF, or ebook editions. Its structured table of contents makes specific packet definitions and normative rules easy to locate. The project is documentation rather than an MQTT broker or client implementation.

gigasetelements-cli is a python based program which allows you to control your Gigaset Elements home security system. It comes with an easy to use CLI (command-line interface) suitable for direct use or cron jobs.

IoT Technical Guide is a Chinese-language learning repository for understanding how high-performance Internet of Things platforms are designed and built. It walks readers through the architecture, concepts, and engineering stack behind IoT systems instead of only listing isolated tools. The guide covers topics such as IoT market context, device models, ThingsBoard source-code learning, MQTT broker setup, CoAP services, message peak shaving, data modeling, and database selection. It is intended for developers who want to learn how real IoT platforms organize devices, messages, protocols, and backend services. The repository is especially useful as a structured study path for readers preparing to build or customize an IoT platform. It functions more as a technical tutorial and roadmap than as a single installable software package.

JetLinks Community is an open-source enterprise IoT platform built with Java, Spring Boot, WebFlux, Netty, Vert.x, Reactor, and related reactive technologies. It is designed to help teams quickly build IoT business systems without starting from a blank backend. The platform supports unified device modeling, unified device access, and centralized management across different device types, vendors, and communication protocols. It can connect devices through TCP, UDP, MQTT, HTTP, TLS, DTLS, and other protocol patterns while hiding much of the complexity of network programming. JetLinks also includes real-time data processing, device alerts, message notifications, data forwarding, geographic features, visualization, and a configurable rule engine. It is best suited for companies that need a customizable IoT foundation for device management, telemetry, automation, and industrial or enterprise monitoring.

MQTT client is designed for communication in Machine to Machine (M2M) and Internet of Things (IoT) contexts and implements MQTT protokol versions 3.1 and 3.1.1. The client is written in Erlang and tested with MQTT servers like Mosquitto and RabbitMQ.

MQTT server is designed for communication in Machine to Machine (M2M) and Internet of Things (IoT) contexts and implements MQTT protocol versions 3.1 and 3.1.1. The server is written in Erlang as OTP application.

This is the Java client SDK for the Velisphere Internet of Things Cloud System. It provides tools and libraries to develop clients that connect as devices or services (with sensors, actors and other configurable function) to Velisphere, where you can connect them with other devices based on an easy to build rules-system, analyze data, locate devices, remote manage them, store binary data in a "dropbox for things", etc. Currently the SDK is available to connect to Velisphere via the AMQP message queuing protocoll, releases for MQTT and ReST will follow. This is still work in progress and will continue to evolve over time. To create your own account for free, go to http://www.velisphere.com

The aim of the project is a lightweight intrusion detection library for embedded devices which supports MSP430 and ARM Cortex based devices. Features include DSP/SIMD support, IoT and embedded protocols, distributed operation, event and history management, tool supported configuration and visualization. There is a Java port that supports less features.
