Home Assistant

Control your smart home from anywhere with the Home Assistant Companion app. Access your local Home Assistant instance on your smartphone or tablet, turning your device into a powerful home automation hub that keeps your data private and under your control.

Manage thousands of smart devices in one place. This app works with the biggest names in smart home technology—Philips Hue, Google Cast, Sonos, IKEA Tradfri, Apple HomeKit, Samsung, LG, Ring, Tesla, and hundreds more. New devices are discovered automatically, so you can add them with just a few taps. Whether you're controlling lights, thermostats, cameras, locks, or entertainment systems, everything connects through a single interface.

Automate your entire home to work the way you live. Set your lights to dim when a movie starts, turn off heating when nobody's home, or trigger security alerts when motion is detected. Share your phone's location and sensor data with Home Assistant to unlock location-based automations for climate control, security, and more. Receive notifications about what matters most—leaks detected, doors left open, package arrivals—with full control over what you're notified about.

Access your home from your car and beyond. Android Auto integration lets you control devices directly from your vehicle's dashboard—open the garage, disarm security, adjust temperature. Create custom widgets on your home screen for one-tap control of any device. Use voice commands with your local voice assistant. Wear OS smartwatch support keeps you connected with notifications, sensor data, tiles, and watch face complications.

Keep your home's data private and secure. Home Assistant runs locally on hardware you own, like Home Assistant Green or a Raspberry Pi. All your automation data stays in your home, not in the cloud. When you need remote access away from home, Home Assistant Cloud offers the most secure and straightforward connection option. Connect to open standards including Z-Wave, Zigbee, Matter, Thread, and Bluetooth for maximum flexibility and future-proofing.

Join over 1 million users who've taken control of their smart homes with privacy and sustainability in mind. Download Home Assistant today and discover a smarter way to live.
