Home Assistant

We support Home Assistant with MQTT autodiscovery.

Requirements

• Supported panel (SP/MG/EVO)
• MQTT Broker (Hass.io has an addon)

Installation

In your Hass.IO installation add 3rd party repository: https://github.com/ParadoxAlarmInterface/hassio-repository

Install Paradox Alarm Interface version 1.3.1+ from there.

Add new pai user in mosquitto for PAI to use. Check your mosquitto addon manual.

Configure the addon config. All configuration parameters from pai.conf.example should be supported even if they do not exist in the default configuration. Home Assistant web UI wants configuration in yaml. But our pai.conf.example is a python file. There may be differences in format. Make sure you understand what is YAML.

Make sure you specify MQTT_HOST properly. If you use hass.io own mosquitto addon core-mosquitto should work. 127.0.0.1 or localhost will not work.

See Configuration

LOGGING_LEVEL_* parameters accept numeric values:

CRITICAL = 50
ERROR = 40
WARNING = 30
INFO = 20
DEBUG = 10
NOTSET = 0

Serial connection

See serial connection method. You need to specify right port and baud rate. Inspect your hass.io for available tty ports. We recommend using a cheap USB to Serial module for 5v instead of raspberry pi pins directly with a level shifter.

SERIAL_PORT = '/dev/ttyUSB0'
SERIAL_BAUD: 9600

Permission denied: '/dev/ttyUSB0'

Login to Host OS

1. Connect a screen and keyboard to your Raspberry PI running Home Assistant Core.
2. Press Enter. You will see homeassistant login
3. Login as root. You will see ha >
4. Type in: login. You will see # (this means you are now on the Home Assistant Core Terminal as root)

Temporary solution

Permissions to the serial device will restore if you replug usb or restart the system:

5. chmod 0666 /dev/ttyUSB0
6. Restart the addon and verify PAI can connect to the serial device.

Permanent solution

7. Find your USB2Serial device's Vendor=xxxx ProdID=xxxx in cat /sys/kernel/debug/usb/devices | grep -E "^([PS]:|$)" output.

Note: if you are unsure which device. Unplug it. Run command. Then plug it back in and run command again. A device will appear in the output. Write down Vendor and ProdID. You will need them later. Let's assume our Vendor is 0403 and ProdID is 6001.

8. Type in: vi /etc/udev/rules.d/paradox.rules
9. Insert the following into the file by pressing i on your keyboard:

Note: Replace idVendor and idProduct attribute values with the ones you wrote down before.

SUBSYSTEMS=="usb", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", SYMLINK+="paradox", MODE="0666"

10. Press Esc
11. Type in (note the : in front of wq): :wq
12. Type in: cat /etc/udev/rules.d/paradox.rules. You should see

SUBSYSTEMS=="usb", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", SYMLINK+="paradox", MODE="0666"

13. Reload udev rules: udevadm control --reload-rules && udevadm trigger
14. Reboot your HASSIO or unplug and plug back your usb to serial device and restart the addon.
15. The addon should now be able to access /dev/ttyUSB0
