⚠️ Deprecated

This version of EXODESÉUS has been superseded by EXODESÉUS Essential,
which features a simplified Firebase-only architecture, Flutter-based cross-platform support, improved performance, and a plug-and-play household model.

👉 See: EXODESÉUS Essential for the current and actively maintained system.

• What is EXODESÉUS (Version 1) and how does it work?
• System architecture overview
• App Preview

EXODESÉUS is a comprehensive application designed to deliver real-time news updates and provide emergency response (SOS) features for selected households.

This document describes the original implementation of EXODESÉUS, including:

• News scraping and storage
• Centralized API and database usage
• User-generated content
• Emergency alert workflows

The app was available on:

• iOS, developed in Swift
• Android, developed in Kotlin

A Raspberry Pi continuously scrapes news data from multiple sources, including:

• Sky News
• LiveUaMap
• Other monitored sources

The collected data is formatted and sent to a centralized API, hosted on Google Cloud Platform (GCP).

Upon receiving data from the Raspberry Pi:

• The API processes the incoming news content
• Articles are stored in a centralized database
• Stored articles become available for retrieval by users

When a user opens or refreshes the EXODESÉUS app:

• The app sends a GET request to the API
• The API retrieves relevant news articles from the database
• The latest news is returned to the client

Version 1 allowed users to submit their own content.

• Users could submit news articles or messages through the app
• The app sent a POST request containing the user’s message
• The API stored this content in the database
• Submitted content became visible to other users

⚠️ Note:
User-generated content has been fully removed in EXODESÉUS Essential.

Available only for selected households.

The app included an SOS tab integrated with:

• Philips Hue lights
• Sonos speakers

Integration was managed via Firebase, which stored device state values. These values were continuously monitored by the Raspberry Pi.

When an SOS alert was triggered:

1. The app updated SOS-related values in Firebase
2. The Raspberry Pi detected these changes
3. Scripts were executed to activate:
   • Audio alerts via Sonos
   • Visual alerts via Hue lights

Upon SOS activation:

• All users received an immediate notification
• The app switched to a CODE RED ALERT screen
• Normal app functionality was restricted to maintain emergency focus

To exit CODE RED ALERT:

• A unanimous decision from connected users was required
• This voting mechanism prevented accidental or malicious deactivation

The Raspberry Pi performed continuous monitoring, including:

• 24/7 DEFCON level tracking

If DEFCON 1 was detected:

• CODE RED ALERT was triggered automatically
• No user interaction was required

• Runs every first Monday of the month at 12:00 PM
• Duration: exactly 1 minute and 26 seconds
• Ensures full system readiness

Users could opt in to receive notifications:

• The app registered a Firebase Cloud Messaging (FCM) token
• Tokens were used to deliver alerts and updates in real time

EXODESÉUS Version 1 was a closed application:

• Access via invite keys only
• Invite keys contained user-specific information
• Available exclusively to selected households

Despite its closed nature, the system architecture allowed for rapid public deployment if required.

EXODESÉUS Version 1:

• Used a centralized API and database
• Supported user-generated content
• Required per-household customization
• Served as the foundation for later improvements

➡️ This version is now deprecated.
➡️ See EXODESÉUS Essential for the modern, maintained implementation.
