Interface to Paradox Alarm Panels

Project description

PAI - Paradox Alarm Interface

Middleware that aims to connect to a Paradox Alarm panel, exposing the interface for monitoring and control via several technologies. With this interface it is possible to integrate Paradox panels with HomeAssistant, OpenHAB, Homebridge or other domotics system that supports MQTT, as well as several IM methods.

It supports MG/SP/EVO panels connected through a serial port, which is present in all panels (TTL 5V), or through a USB 307 module. It also supports connections using the IP150 module, both directly (firmware version < 4.0 or >= 4.40.004), and through the SITE ID (firmware versions >4.0).

Support for Magellan, Spectra and EVO panels is very stable. If you find a bug, please report it.

For further information and detailed usage refer to the Wiki.

If you are having issues, or wish to discuss new features, join us at our Gitter community

On Android, if you install MQTT Dash, and follow the instructions you will automatically get a panel like this: mqtt_dash

Things you need to have to be able to connect

We support two connection options: via Serial and via IP150 Module.

For all connection methods

  • PC Password: 4 digit [0-9a-f] password. Can be looked up in Babyware (Right click on a panel ⇾ Properties ⇾ PC Communication (BabyWare) ⇾ PC Communication (BabyWare) ⇾ PC Password)

In case of IP150 you need additionally:

  • IP Module password: Default is paradox
For IP150 firmware > 4.0 if you connect via Paradox Cloud (SWAN)
  • Email registered in the site

How to use

See wiki

Tested Environment

Tested in the following environment:

  • Python 3.6, 3.7, 3.8
  • Mosquitto MQTT Broker >v 1.4.8
  • OrangePi 2G-IOT, NanoPi NEO, and Raspberry Pi 3 through their built in Serial Port (with a level shifter!), or a USB RS232 TTL adapter (CP2102, PL2303, CH340, etc..)
  • Ubuntu Server 16.04.3 LTS
  • Paradox MG5050, SP7000 and EVO panels
  • Signal Cli through a DBUS interface
  • SIM900 module through a serial port
  • Serial over TCP (ESP32 or Arduino connected to the panel's serial port acts as a proxy)


  • João Paulo Barraca - @jpbarraca - Main code and MG/SP devices
  • Jevgeni Kiski - @yozik04 - Main code and EVO devices
  • Ion Darie - @iondarie - PAI Logo, Homebridge integration, testing


This work is inspired or uses parts from the following projects:


  • Ivan Markov - @ivmarkov - Multi-platform Docker builds with Travis


Paradox, MG5050 and IP150 are registered marks of PARADOX. Other brands are owned by their respective owners.

The code was developed as a way of integrating personally owned Paradox systems, and it cannot be used for other purposes. It is not affiliated with any company and it doesn't have have commercial intent.

The code is provided AS IS and the developers will not be held responsible for failures in the alarm systems, or any other malfunction.


João Paulo Barraca @jpbarraca does not accept any donations.

Raised money will be spent on different hardware required for PAI development.
