ha-mqtt-autodiscovery

Works with MQTT brokers (Mosquitto), paho-mqtt Python library, and Home Assistant MQTT integration. Home Assistant MQTT Auto-Discovery

Automatically register IoT devices and sensors with Home Assistant by publishing MQTT discovery configurations.

MQTT auto-discovery allows devices to automatically appear in Home Assistant without manual YAML configuration. Publish a JSON config to the discovery topic and HA creates the entity automatically.

Configures and publishes MQTT auto-discovery messages to automatically register IoT devices and sensors with Home Assistant, defining discovery payloads with device classes, state classes, units, and device grouping for multi-sensor devices. Use when integrating custom IoT devices, creating MQTT sensors, building ESP32/ESP8266/Pi-based devices that auto-register with HA, or implementing resilient MQTT patterns with offline queuing and auto-reconnect.
