Zigbee2mqtt is a service that functions as a bridge between Zigbee radio signals and the MQTT messaging protocol. It acts as a smart home hardware controller, enabling the management and communication of sensors, lights, and switches through local USB or network-based radio adapters.
The project serves as a network manager for local mesh environments, handling the pairing of new hardware and the ongoing administration of device connections. It translates proprietary radio payloads into standardized data structures using a declarative schema, ensuring that device states are reconciled in real time and exposed through a centralized message broker.
The software provides a comprehensive interface for smart home device management, including the discovery of hardware adapters and the maintenance of network topology. It facilitates the integration of wireless hardware into broader automation platforms by decoupling device-specific logic from client applications.
