Zigbee2MQTT

Zigbee2MQTT is a bridge that connects Zigbee devices to an MQTT broker, allowing you to use Zigbee devices without the vendor’s proprietary hub. It translates Zigbee events and commands into MQTT topics so they can be integrated with many home automation systems.

Key Features

• Works with a wide range of Zigbee adapters and an extensive list of supported devices
• Publishes device events to MQTT and accepts MQTT commands to control devices
• Maintains a local state database for paired devices and their capabilities
• Web-based interfaces for monitoring and configuration (via companion frontends)
• Device model mapping via converters to support diverse vendor implementations

Use Cases

• Integrate Zigbee lights, sensors, and switches into an MQTT-based smart home setup
• Replace vendor Zigbee bridges while keeping local control and interoperability
• Build automations across platforms that can subscribe to and publish MQTT topics

Limitations and Considerations

• Requires a compatible Zigbee USB adapter/coordinator and an MQTT broker
• Device compatibility depends on available converters; uncommon devices may need custom support

Zigbee2MQTT provides a practical way to standardize Zigbee device control through MQTT, enabling broad integration options across smart home ecosystems. It is well-suited for users who want flexibility and independence from vendor-specific gateways.
