Entities and actions

Device entities

Every device has a real assist_satellite.*. Enabled cameras create camera.*; media_player.* exists but is disabled by default. Runtime settings use EntityCategory.CONFIG, diagnostics use EntityCategory.DIAGNOSTIC.

Enabled sensors cover battery, charging, power source, Wi-Fi signal, network and IP, active tab, online/last seen, app/Android version, uptime, storage, display geometry and screensaver, voice, camera and service status. Available light, proximity, acceleration, gyroscope, magnetic field, pressure, humidity, temperature, rotation and step sensors are created disabled.

Switches, numbers and selects control profile, brightness, screen behavior, voice/wake word, VAD, audio route, screensaver, camera FPS/quality/resolution/transport, media player and sensor interval. Buttons reload configuration, wake the screen or restart the service.

Voice announcements and conversations use standard assist_satellite actions; playback uses media_player. Widgets cannot call arbitrary HA services. The integration extracts entities referenced by the effective dashboard, sends only their states, and permits a fixed typed operation set per domain.
