Home Assistant

Home Assistant is the world's largest open-source home automation platform, putting local control and privacy first. Founded in 2013 by Paulus Schoutsen, it has grown to serve over 2 million households and was recognized as a top open-source project by contributors on the platform in 2025. The platform supports 1,500+ integrations with over 1,000 brands including Philips Hue, Nest, Sonos, Ring, IKEA TRADFRI, and MQTT devices. Home Assistant runs entirely locally on hardware like Raspberry Pi, Home Assistant Green (32 device integrations), and Home Assistant Yellow (with Zigbee and Matter support built-in), requiring no cloud account for core functionality. Key features include: powerful automation engine with YAML and visual editors, customizable dashboards (Lovelace UI), voice assistant (Assist) with local wake word detection via Wyoming Protocol, companion apps for iOS/Android/Wear OS, home energy management with real-time consumption tracking, NFC tag automation, Blueprint templates for easy setup, and integration with Amazon Alexa and Google Assistant. The project is governed by the Open Home Foundation, a non-profit ensuring it cannot be sold or acquired. As of 2026, the latest release is 2026.6.4, with the codebase available on the platform with 75,000+ stars.
