KioskHQ: Kiosk Browser

KioskHQ turns any Android tablet or phone into a locked-down, fullscreen web kiosk — perfect for Home Assistant wall panels, digital signage, point-of-sale, info displays, and dedicated single-purpose devices.

The full kiosk browser, lockdown and screensaver are FREE. A single one-time unlock — no subscription — adds the automation and integration layer (REST API, MQTT, Home Assistant, the JavaScript interface, motion detection, dashboard rotation, remote admin and tablet care).

KIOSK LOCKDOWN
• Fullscreen immersive WebView with the system bars hidden
• Lock-task / screen-pinning, with full device-owner lockdown when provisioned
• Status-bar swallow, hardware-key blocking, and a watchdog that restarts the app
• PIN-protected exit via a configurable corner multi-tap
• Optional launcher (HOME) replacement so the kiosk owns the device

WEB BROWSER BUILT FOR KIOSKS
• Start URL, URL allow/block lists, custom user agent, zoom and desktop mode
• Auto-reload on a timer, on screen-on, and on network reconnect
• Multi-tab support and multi-dashboard rotation
• File uploads, camera/mic access, and fullscreen HTML5 video

AUTOMATION & REMOTE CONTROL (one-time Pro unlock)
• Built-in REST API on port 2323 — query device info and drive the device remotely
• MQTT: publishes device state and events, with Home Assistant MQTT auto-discovery
• A JavaScript interface so your web app can control the device directly
• Wire-compatible command, event, and JSON formats — existing Home Assistant and other integrations work unmodified

SENSORS & MEDIA
• Camera motion detection wakes the screen and resets the idle timer
• Face/presence detection, QR/barcode scanning, camera snapshots and screenshots
• Text-to-speech, sound playback, and volume control
• Screensaver and Daydream with image, video, website, or true-black playlists

ALWAYS-ON TABLET CARE
• Scheduled screen on/off and brightness control
• Battery alerts and best-effort charge limiting to protect long-lived wall tablets
• Self-healing restart and network-reconnect handling

KioskHQ is a from-scratch native app built for reliability on devices that run 24/7. Set it up once, mount it on the wall, and forget about it.
