ZKTeco LAN Agent for Your Local Environment

Bridge non-ADMS ZKTeco devices (Ethernet / PC Connection only) to your application via ADMS HTTP. Runs on a Office LAN laptop or Pi. If LAN is not available, the device should

Device(s) ──TCP 4370──► Office Laptop (agent) ──HTTP :80 /iclock/*──► Production Cloud Server

Package on PyPI: zkteco-lan-agent

Install (Office Laptop)

Use Python 3.10–3.12 (3.12 recommended). The ZKTeco client is PyPI package pyzk (from zk import ZK), not the unrelated zk package.

With uv (recommended)

uv python install 3.12
uv tool install --python 3.12 zkteco-lan-agent
# or one-off:
uvx --python 3.12 zkteco-lan-agent --config devices.yaml

With pip

# create a 3.12 venv first if your system python is 3.14
python3.12 -m venv .venv
source .venv/bin/activate   # Windows: .venv\Scripts\activate
pip install zkteco-lan-agent
zkteco-lan-agent --config devices.yaml

If you stay on system Python 3.14 and must compile

sudo apt install python3-dev build-essential
uv pip install zkteco-lan-agent

From this repo (development)

cd zkteco_lan_agent
uv sync --python 3.12
uv run zkteco-lan-agent --config ../devices.yaml

Copy and edit config:

cp devices.yaml.example devices.yaml   # from repo root, or create manually

Example devices.yaml/devices.yml:

server_url: http://subdomain.domain.com
poll_interval_seconds: 30
command_poll_interval_seconds: 10
heartbeat_interval_seconds: 60

devices:
  - name: Device One
    device_ip: 192.168.1.100
    device_port: 4370
    device_sn: "CHANGEME_SN"
    comm_password: 0
    timezone: Asia/Dhaka

  - name: Device Two
    device_ip: 192.168.1.100
    device_port: 4370
    device_sn: "CHANGEME_SN"
    comm_password: 0
    timezone: Asia/Dhaka 

  ..........

Keep the laptop awake (disable sleep while the gym is open).

The agent polls attendance regularly and also syncs device users (USERINFO, including card numbers) every userinfo_sync_interval_seconds (default 300). That is what populates the Fingerprints page with card holders from the device. You can also click Sync Now on the Devices page to pull users immediately.

Run as a background service

systemd does not exist on Windows. Use the section that matches the OS.

Linux — systemd

# After: uv tool install zkteco-lan-agent
which zkteco-lan-agent   # note the path, e.g. ~/.local/bin/zkteco-lan-agent

sudo cp zkteco-lan-agent.service /etc/systemd/system/
# edit ExecStart, WorkingDirectory (config path), User=
sudo systemctl daemon-reload
sudo systemctl enable --now zkteco-lan-agent
sudo systemctl status zkteco-lan-agent

Windows — Task Scheduler (built-in) — Always Use the Latest Version

If you installed zkteco-lan-agent using uv, you should use uv for upgrades, as zkteco-lan-agent upgrade is not a built-in command of the agent and does not exist. Instead, run uv pip install --upgrade zkteco-lan-agent before starting the agent.

1. Create start-lan-agent.bat like this:

@echo off
cd /d C:\gym\agent
uv pip install --upgrade zkteco-lan-agent
zkteco-lan-agent --config devices.yaml

2. In Task Scheduler, Create Task, set to run at startup: Action: start the .bat file created above.
3. Enable restart on failure; uncheck “Stop if runs longer than…”.

This setup will upgrade zkteco-lan-agent to the latest available version every time before launching it, as long as you installed using uv.

Windows — NSSM (Windows Service)

nssm install ZktecoLanAgent "C:\Users\You\AppData\Local\Programs\Python\Python312\Scripts\zkteco-lan-agent.exe"
nssm set ZktecoLanAgent AppDirectory "C:\gym\agent"
nssm set ZktecoLanAgent AppParameters "--config devices.yaml"
nssm set ZktecoLanAgent AppRestartDelay 10000
nssm start ZktecoLanAgent

Dashboard registration

Field	Value
Profile	ZKTeco
Model	K40 (or actual model)
Mode	TCP Relay
Serial	Exact hardware SN

Production ADMS smoke tests

curl -v "http://<tenant>.fitssort.com/iclock/cdata?SN=<YOUR_SN>"
curl -v "http://<tenant>.fitssort.com/iclock/getrequest?SN=<YOUR_SN>"

Use http:// only (HTTPS ADMS paths are not routed).

Card + fingerprint

• Enroll fingerprints from the web app (ADMS or TCP Relay) or on the device.
• Provision cards from the app so USERINFO includes Card=.
• Device needs a card reader module for card taps.

Publish to PyPI (maintainers)

Uses uv.

One-time setup

1. Create a PyPI account at https://pypi.org (and TestPyPI at https://test.pypi.org).
2. Create an API token (Account → API tokens). Scope: entire account or project zkteco-lan-agent.
3. Prefer env vars (never commit tokens):

export UV_PUBLISH_TOKEN=pypi-AgEIcHlwaS5vcmc...   # PyPI
# or for TestPyPI:
export UV_PUBLISH_TOKEN=pypi-...                 # TestPyPI token

Build & test locally

cd zkteco_lan_agent
uv sync --group dev
uv run pytest
uv build
# artifacts in dist/: .whl and .tar.gz

Publish to TestPyPI first

cd zkteco_lan_agent
uv build
uv publish --publish-url https://test.pypi.org/legacy/ --token "$UV_PUBLISH_TOKEN"

Install from TestPyPI to verify:

uv tool install --index https://test.pypi.org/simple/ --index-strategy unsafe-best-match zkteco-lan-agent

Publish to PyPI

1. Bump version in pyproject.toml (and ensure changelog/notes if you keep them).
2. Build and publish:

cd zkteco_lan_agent
uv build
uv publish --token "$UV_PUBLISH_TOKEN"

Or interactive (uv prompts for username __token__ and the API token as password):

uv publish

Version bumps

Edit version in pyproject.toml. Reinstall picks up __version__ via importlib.metadata.
