ESSL Biometric Attendance

Overview

  • This module is an addon to Odoo Attendance that enables synchronization of attendance data captured by ESSL biometric devices into Odoo.
  • This module does NOT connect directly to the biometric device, it works with the database created and maintained by ESSL software (Desktop or Web-based, eTimeTrack). The module fetches attendance data from that database and creates corresponding records in Odoo.

How the ESSL Ecosystem Works

  • ESSL devices always rely on an ESSL-provided application to download and store attendance data.
  • ESSL provides two common options:
    1. ESSL Desktop Application
    2. ESSL Web Application (eTimeTrack)
  • Both applications store attendance data in a database (commonly MS SQL Server).
  • This Odoo module integrates at the database level, not at the device level.

Data Flow & Architecture

Key Takeaway

  • The module reads attendance from MS SQL Server
  • The ESSL application must already be syncing devices to database

Supported Attendance Modes

  1. Desktop Application Mode
    • Attendance is downloaded manually from device to ESSL Desktop Software
    • Data is stored in MS SQL Server
    • Odoo fetches attendance when sync is triggered
    • Attendance in Odoo is NOT live
  2. Web Application Mode (eTimeTrack)
    • Devices automatically sync with eTimeTrack
    • Attendance is continuously stored in MS SQL Server
    • Odoo fetches attendance periodically
    • Attendance in Odoo is near real-time (live)

Key Features

  • Seamless integration with the Odoo Attendance module.
  • Fetches attendance data directly from the ESSL MS SQL Server database.
  • Supports both manual (desktop) and automatic (eTimeTrack) attendance workflows.
  • Configurable synchronization logic.
  • Reliable database-level integration (no device instability).
  • Scalable for multiple biometric devices handled by ESSL software.

Technical Prerequisites

  1. Database
    • MS SQL Server used by ESSL Desktop or eTimeTrack
    • Database must contain attendance data populated by ESSL software
  2. Network Connectivity
    • One of the following must be true:
      • Odoo server is in the same network as MS SQL Server
        • OR
      • MS SQL Server is accessible remotely (IP, Port, Firewall rules configured)
  3. Python Dependency
    • The following Python library must be installed on the Odoo server:
      1. pip3 install pymssql
    • This library enables Odoo to communicate with MS SQL Server.

Current Limitations

  • Supported: Only MS SQL Server.
  • Not supported by default:
    • MS Access
    • MySQL
  • Support for MS Access or MySQL can be added based on client requirements.

What This Module Does NOT Do

  • Does NOT connect directly to biometric devices
  • Does NOT replace ESSL Desktop or eTimeTrack software
  • Does NOT pull attendance from Excel or PDF reports

This module strictly works with ESSL-managed databases.

Screenshots

Configure SQL Server Connection

  • Fill SQL Server Connection Details.

Attendance Sync Timing

  • Select how frequently Odoo should fetch new attendance data.

Add Employee Biometric Code

  • You need to add a biometric code in employee's hr settings.

Attendance Log

  • In Attendance Logs Menu View the detailed attendance logs fetched directly from the Biometric Attendance.

Attendance

  • In Attendance Menu View automatically creates attendance records with checked in and checked out time.

FAQs

Frequently Asked Questions

  1. Q1. What does this module do?
    • This module seamlessly synchronizes attendance data from ESSL biometric systems into Odoo’s Attendance application.
  2. Q2. Can I get live attendance in Odoo?
    • Yes, but only if you use ESSL eTimeTrack (Web Application). If you use the desktop application, attendance must be downloaded manually.
  3. Q3. Can I use this module if my attendance data is stored in a different SQL Server database?
    • Yes, If that database contains ESSL attendance logs and accessible remotely from the Odoo server, Additional Customization Needed.
  4. Q4. Does Odoo need to connect directly to the biometric device?
    • No. Odoo does not connect directly with the biometric device. It connects only to the database (such as MS SQL Server) where the ESSL software stores attendance information.
  5. Q5. Can I control how often attendance data is synchronized?
    • Yes. You can configure the attendance synchronization frequently as you choose.
  6. Q6. Can this module synchronize attendance from multiple MS SQL Server databases?
    • Yes. The module supports multiple MS SQL Server database connections, with each connection operating independently using its own scheduled synchronization.
  7. Q7. Is this module compatible with Odoo Online or Odoo.sh?
    • Yes. The module works smoothly with Odoo Online, Odoo.sh, as well as On-Premise.
  8. Q8. Can Odoo fetch attendance from Excel files exported by ESSL?
    • No. This module fetches attendance directly from the ESSL database, not from reports.
  9. Q9. Do I need to install anything on the ESSL server?
    • No additional ESSL-side installation is required. Only ensure:
      • MS SQL Server is accessible
      • Correct database credentials are available

Summary

  • This module provides a clean, reliable, and scalable bridge between ESSL attendance systems and Odoo Attendance by integrating at the database level.
  • For customization or extended database support, please contact the developer.
