KingKiosk

KingKiosk turns any Android phone, tablet, or dedicated kiosk device into a remotely programmable multi-window display surface — controlled in real time over MQTT.

It's not digital signage. It's not a kiosk app. It's not a dashboard. It's all of those, and none of them, because you decide what every screen becomes by sending it instructions.

A REAL WINDOWING SYSTEM ON ANDROID
Compose multiple widgets at once on the same screen — a clock, a live camera feed, a Home Assistant dashboard, weather, calendar, and a media player, each in its own resizable, independently controllable tile. Floating mode for pixel-perfect layouts. Tiling mode for automatic grids.

35+ BUILT-IN WIDGETS
Clocks, weather, media player, YouTube, image carousels, gauges, charts, maps, PDF viewer, animated text, RSS feeds, MQTT-driven images and buttons, an Alarmo security panel, an LED light panel, DLNA player, intercom, games, calendar with bidirectional sync, and a real-time canvas widget for declarative graphics.

MQTT-NATIVE
Every widget, every layout, every system setting is addressable over MQTT. 100+ commands. Build automations in Home Assistant, Node-RED, or any tool that speaks MQTT. Save layouts as named "screen states" and recall them on schedule.

DEEP HOME ASSISTANT INTEGRATION
Auto-discovers to Home Assistant. Publishes sensor data (battery, network, location, presence, person/object detection). Responds to automations. Bidirectional calendar sync.

KIOSK MODE — TWO LEVELS
Standard kiosk works on any Android device — set King Kiosk as your launcher and approve the requested permissions. Full Device Owner lockdown is supported for fleet-managed kiosk hardware where IT controls the device. Perfect for wall tablets, lobby screens, smart-home dashboards, retail panels, and dedicated control surfaces.

AI VOICE CONTROL
Connect to Home Assistant conversation agents, Anthropic Claude, OpenAI, Google Gemini, or local Ollama. Your displays can listen, understand, and respond.

INTERCOM & BROADCAST
Two-way WebRTC audio between devices. Room-to-room paging. Full-fleet broadcast.

DETECTION & MOTION
Person, object, and facial recognition (on-device or via the optional Feature Server). Motion-triggered camera snapshots. All published to MQTT for use in Home Assistant automations.

PRIVACY-FIRST
Your data stays on your network. Crash reports are off by default and require explicit opt-in. No analytics, no tracking, no cloud lock-in.

OPTIONAL ENTERPRISE SECURITY
Optional HMAC-SHA256 command signing ensures only authorized commands reach your displays. Perfect for multi-site deployments.

BUILT FOR FLEETS
One device or a thousand — replicate entire layouts across the fleet with a single MQTT message. Schedule layout changes by time of day or day of week.
