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 (firmwares below 7.50.000) 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 (ip module 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.

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

We do not recommend using SWAN because of

Firmware Upgrade WARNING:

Do not upgrade EVO firmware versions to 7.50.000+ if you use Serial connection. Process is irreversible! Paradox introduces serial communication encryption which most probably will break our PAI ability to talk to the panel.

How to use

See wiki

Tested Environment

Tested in the following environment:

  • Python 3.6, 3.7, 3.8, 3.9, 3.10, 3.11
  • Mosquitto MQTT Broker > 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)
