aritech-client 0.2.1

Unofficial Python client library for ATS alarm panels

ATS Advisor Client for Python (Unofficial)

An unofficial, community-developed async Python client to monitor and control ATS alarm panels over your local network.

This project is not affiliated with, endorsed by, or supported by UTC, Carrier, or any of their subsidiaries.

Compatibility

This library supports the ACE 2 ATS version 6 protocol, which works with Advisor Advanced panels (ATS1500A, ATS3500A, ATS4500A series). The older version 4 protocol for Master/Classic panels is not supported.

Note that protocol behavior may vary based on panel firmware version. This library has been tested with a limited set of panels. If you encounter issues, please mention your panel model and firmware version when reporting.

Requirements

• Python 3.11 or higher
• pycryptodome

Installation

pip install aritech-client

Or install from source:

cd aritech-py
pip install -e .

Configuration

Create a config.json in the current directory or ~/.aritech/config.json:

{
  "host": "192.168.1.100",
  "port": 3001,
  "pin": "1234",
  "encryptionPassword": "your-24-char-password!!"
}

CLI Usage

aritech-cli --help

Or run directly with Python:

python -m aritech_client.cli --help

For troubleshooting, enable debug logging:

LOG_LEVEL=debug aritech-cli zones
# or
aritech-cli --debug zones

Note: Debug logs may contain sensitive information such as your PIN code.

Library Usage

The library uses asyncio for all communication with the panel:

import asyncio
from aritech_client import AritechClient, AritechConfig

async def main():
    config = AritechConfig(
        host="192.168.1.100",
        port=3001,
        pin="1234",
        encryption_password="your-24-char-password!!",
    )

    async with AritechClient(config) as client:
        await client.initialize()

        # Get zone names and states
        zones = await client.get_zone_names()
        states = await client.get_zone_states([z.number for z in zones])

        for zone in zones:
            state = next((s for s in states if s.number == zone.number), None)
            print(f"Zone {zone.number}: {zone.name} - {state.state if state else 'unknown'}")

        # Arm area 1
        await client.arm_area(1, "full")

        # Disarm area 1
        await client.disarm_area(1)

asyncio.run(main())

Monitoring

import asyncio
from aritech_client import AritechClient, AritechConfig
from aritech_client.monitor import AritechMonitor

async def main():
    config = AritechConfig(
        host="192.168.1.100",
        port=3001,
        pin="1234",
        encryption_password="your-24-char-password!!",
    )

    async with AritechClient(config) as client:
        await client.initialize()

        monitor = AritechMonitor(client)

        monitor.on_zone_changed(lambda e: print(f"Zone {e.id} changed: {e.new_data}"))
        monitor.on_area_changed(lambda e: print(f"Area {e.id} changed: {e.new_data}"))
        monitor.on_output_changed(lambda e: print(f"Output {e.id} changed: {e.new_data}"))
        monitor.on_trigger_changed(lambda e: print(f"Trigger {e.id} changed: {e.new_data}"))

        await monitor.start()

        # Keep running until interrupted
        try:
            while monitor.running:
                await asyncio.sleep(1)
        except KeyboardInterrupt:
            monitor.stop()

asyncio.run(main())
