Flask Integration with Odoo (Middleware & System Migration)

The existing Flask-based biometric and access control system was redesigned and implemented within Odoo 18 to centralize device management, attendance processing, user enrollment, access control, and device communication.

The system enables real-time synchronization between biometric devices and Odoo using WebSocket communication, automated command processing, and structured data management.

Scope of Implementation

Device Management

• Development of Odoo models for biometric devices and configuration management

• Device registration and status tracking functionality

• Management of active device connections via WebSocket communication

Attendance & Log Synchronization

• Synchronization of attendance records from biometric devices to Odoo

• Storage and management of device logs within Odoo

• Processing and retrieval of attendance data from connected devices

User & Enrollment Management

• Synchronization of user data between Odoo and biometric devices

• Management of user enrollment information

• Support for user creation, update, and removal on devices

Access Control Management

• Configuration of access day and access week rules

• Management and synchronization of device access policies

• Processing of device lock and access control commands

Device Command Management

• Command queue system for device communication

• Generation, tracking, and execution status management of commands

• Support for user synchronization, deletion, and access rule updates

WebSocket Communication

• Implementation of WebSocket-based real-time communication between Odoo and devices

• Handling of device registration, attendance logs, user synchronization, and command execution

• Management of device connection and disconnection events

Automated Background Processing

• Scheduled cron jobs for processing pending device commands

• Automatic retry mechanism for offline device handling

• Tracking of command execution status and synchronization history

Testing Framework

• Development of Python-based mock device scripts for simulation

• Validation of device communication workflows including registration, logs, users, and commands

• End-to-end testing of system synchronization processes

Process Flow

Key Deliverables

• Biometric device management system

• Attendance and log synchronization module

• User and enrollment management system

• Access control configuration framework

• WebSocket-based device communication layer

• Device command queue and processing engine

• Automated synchronization using scheduled jobs

• Mock device testing framework

• Logging, monitoring, and error handling mechanisms

The implementation successfully migrated and integrated Flask-based biometric system functionality into Odoo 18, enabling centralized control, real-time synchronization, and scalable device management within the ERP ecosystem.
