Hi,

When facing a timeout issue integrating a Zkteco F18 biometric device with Odoo's attendance module, start by checking the Odoo server's firewall to ensure it's not blocking communication to the device's IP address and port. Verify the port number in the Odoo module settings and confirm that both the Odoo server and the device are on the same network (same subnet).

Also, consider potential module bugs or compatibility issues, and check the Zkteco device's configuration, including the device ID and communication protocol. Ensure the Odoo user has sufficient permissions and that the time is synchronized between the server and the device.

Hope it helps
