Paradox Alarm - Serial - MQTT interface

This code allows you to connecet Paradox MG5050 via serial interface via MQTT.

Credit

This is based on work in these two repositories:

• https://github.com/Tertiush/ParadoxIP150v2
• https://github.com/jpbarraca/ParadoxMulti-MQTT

Improvements

Improvements over the above scripts:

• Better code handling of alarm situations. Both the above failed to notify of zones under alarm.
• Handles more messages from the alarm.
• More zone states (including alarm, bpass, fire_alarm etc.)
• More logic for tracking zone/alarm/partition states.
• Publishes in Homie standard

Install

1. Clone the repository
2. cd into the project folder
3. Copy the config_sample.py to config.py and uncomment the settings you wish to change. The commented values represent the default values.
4. Create a virtual enivornment with python3 -m venv venv
5. Activate it with source venv/bin/activate
6. Install requirement with pip install -r requirements.txt
7. Run with python main.py.
8. Use the supplied paradox_mqtt.service to setup a service to start this automatically.

MQTT Topics

The script publishes alarm details under various topics (as per defaults):

This publishes on the Homie standard.

Some high level topics are published:

• homie/alarm/panel/ contains panel details such as battery states etc.
• homie/alarm/panel/alarm/ is the alarm state
• homie/alarm/partition1/ contains the partition 1 arm states and alarm states.
• homie/alarm/partition2/ contains the partition 2 arm states and alarm states.
• homie/alarm/troubleindicators/ contains trouble indicators.
• homie/alarm/moduletroubleindicators/ contains module trouble indicators.
• homie/alarm/output1/ contains output details for output 1.
• homie/alarm/zone1/ contains zone details for zone 1.
• homie/alarm/zone1/open contain is the open status of a zone (e.g. movement for PIRs).
• homie/alarm/zone1/bypass contains whether zone is bypassed.
• homie/alarm/zone1/alarm whehter the zone is causing an alarm.
• homie/alarm/zone1/lowbattery whether the zone battery is low (for wireless battery powered PIRs)

Settable topics contain the property settable. For example homie/alarm/zone1/bypass/$settable true indicates that we can publish to this topic to set a value (and consequently bypass the zone).

Arming can be done in several ways but perhaps the easies is setting homie/alarm/partition1/armstate to an integer as follows:

• 0 - Disarmed
• 1 - Stay Armed
• 2 - Sleep Armed
• 3 - Armed
