Home Assistant

The companion application provides a mobile interface for the Home Assistant home‑automation platform, enabling users to receive and act on notifications, control devices, and access Home Assistant’s features from smartphones and wearable devices. It supports secure connections to a Home Assistant server and offers integrations for iOS, Android, Apple Watch, Wear OS, Android Auto, CarPlay, and Meta Quest, allowing control of lights, sensors, and other entities directly from those environments.

Key functionality includes actionable notifications that keep users informed even when away, URL handling for deep linking into specific Home Assistant screens, and the ability to run custom actions from watch complications or vehicle interfaces. The app also supplies a gallery of screenshots and troubleshooting resources to assist with setup and problem resolution.

Designed for macOS as a core platform, the companion app is released as a stable product and is available through official distribution channels, with beta versions offered via TestFlight for iOS and standard releases for Android.
