HomeAutio.Mqtt.GoogleHome is a software bridge that connects Google Home's Actions API with MQTT, enabling home automation integration without relying on a cloud service provider. It includes an in-process OAuth 2 server to handle Google Actions Account Linking and provides fulfillment for SYNC, QUERY, and EXECUTE intents. The software translates these intents into MQTT messages and vice versa, allowing seamless communication between Google Home and MQTT-based devices. It is designed for developers and home automation enthusiasts who want to integrate Google Home control with their existing MQTT infrastructure while maintaining self-hosting capabilities. Configuration and Google Device metadata definitions are documented in the project wiki.
