ParadoxMqtt32

This project uses an ESP32 to read the events of the serial bus on Paradox alarm systems and send them to an MQTT server

Making a connection

Connect the panel: -Connect Alarm system serial to ESP32 using RX2/TX2 of ESP32

Arduino IDE settings

Set the Hassio flag to 1 for Home assistant, and check out the wiki (Home Assistant in V2)

The 37 byte message is broken down into a json message with "Event Group" and "Sub-group", and one more dummy attribute which is the zone/partition label.

See the wiki for more info on Groups and Sub-groups

After flashing the ESP board, connect to it's Wi-Fi (paradox32CTL password: configParadox32), open the 192.168.4.1 IP address in your browser, input your Wi-Fi credentials and MQTT server address. That's all.

MQTT Topics

Topic Notes
paradox32CTL/out All alarm event messages
paradox32CTL/status The program messages
paradox32CTL/status/ACFailure ACFailure if true there is a ACFailure
paradox32CTL/in Input topic

HomeAssistant MQTT Topics

Topic Notes
paradox32CTL/hassio/y/zoneX Where x is zone number from 1-32
paradox32CTL/hassio/y/zoneX Gives values ON/OFF
paradox32CTL/hassio/Arm/y Gives values: disarmed, armed_home, armed_away, triggered
y is the partition always 0 in single partition systems

Sending commands

The command payloads are in JSON. Template:

{
 "password":"1234",
 "Command":"arm",
 "Subcommand":"0"
}

The password is the user's 4/6 digit password. set USE6DigitCode true in main.h file

A command can be any of the following:

  • arm
  • disarm
  • sleep
  • stay
  • bypass
  • armstate
  • panelstatus
  • setdate
  • PGM_ON
  • PGM_OFF

Subcommands depending on the main command

Main Command Subcommand
arm,sleep,disarm 0-1 partition
bypass 0-31 zone number -1
panelstatus '0' panel data
panelstatus '1' Partition state & zone status
