Danboard: Standalone Fire TV Smart Display & Family Calendar
An open-source, zero-subscription smart display and calendar dashboard engineered specifically for Amazon Fire TV (as well as Android TV and web browsers). Runs 100% standalone on device hardware with direct Google Calendar iCal sync, live Open-Meteo weather, and 4K rotating landscape photography.
The Friction: Proprietary Hardware & Subscription Fatigue
Smart family calendars and wall displays (such as Skylight Calendar, DAKboard, and Hearth Display) solve a genuine household coordination problem. But the modern ecosystem comes with significant friction:
- Mandatory Monthly Subscriptions: Paying $10 to $20/month indefinitely just to display calendars and weather data you already own.
- Proprietary & Fragile Hardware: $300+ single-purpose screens with locked-down operating systems that become e-waste when vendor cloud servers shut down.
- Fragile Home Server Setups: DIY alternatives typically require a Raspberry Pi, Docker container, or an always-on desktop computer running 24/7 on the local network.
Architecture & Key Innovations
100% Standalone on Fire TV
Compiled into a lightweight ~4.2 MB Android APK using Capacitor and Android WebView. Executes entirely on the Fire TV Stick hardware with zero server dependency.
Direct iCal & RRULE Parsing
Connects directly to Google Calendar secret iCal addresses. Uses ical.js for client-side recurrence expansion, bypassing browser CORS restrictions natively on Android.
Zero-Key Open-Meteo Weather
Direct client integration with Open-Meteo for live temperatures, humidity, wind speeds, and a 3-day forecast without requiring API keys, accounts, or billing quotas.
4K Landscape Photo Wallpapers
Cycles curated high-resolution landscape photography with smooth crossfade transitions, auto-contrast vignettes, and an optional rotating family photo frame widget.
24/7 Smart Display Mode
Configured with Android's FLAG_KEEP_SCREEN_ON window flag so your Fire TV screen stays active without dimming, timing out, or falling into ambient sleep.
Native Ring Doorbell PiP
Because it runs natively within Fire OS, Alexa and Ring Doorbell automatically overlay Picture-in-Picture camera video feeds when someone rings the front door.
Quick Start & Installation
1. Visual Web Preview (Mac / PC)
Test and configure calendars comfortably from your computer browser before deploying to your TV:
Open http://localhost:5173 in your browser. Press S to open the Settings modal and configure Google Calendar iCal feeds, coordinates, and display options.
2. Fast Fire TV Deployment via ADB over Wi-Fi
Once configured, push the compiled APK directly over your home Wi-Fi to your Fire TV Stick:
Danboard appears immediately under Your Apps & Channels on Fire OS, booting straight into your full-screen family dashboard.
Open Source & Free Forever
Danboard is completely open source under the MIT license. Fork it, customize your widgets, or contribute new display integrations.
