Anyone intrested in a esp32 version running micropython check here https://github.com/maragelis/micropython_paradox
ParadoxRs232toMqtt
This project uses a WEMOS ESP8266 to read the events of the serial bus on Paradox alarm systems and send them to an MQTT server
Making a connection
There are 2 ways to connect the devices together:
- Alarm system serial to WEMOS through RX/TX
- paradoxTX into GPIO15 (WEMOS D8), paradoxRX to GPIO13 (WEMOS D7), using serial_swap 1
Arduino IDE settings
Edit the PubSubClient.h header file and change MQTT_MAX_PACKET_SIZE to 256
Libraries:
- Arduino Core 2.4.1
- WifiManager by tzapu 0.12.0
- PubSubClient by Nick O`Leary 2.6.0
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 WEMOS board, connect to it's Wi-Fi (paradoxdCTL), 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 |
|---|---|
| paradoxdCTL/out | All alarm event messages |
| paradoxdCTL/status | The program messages |
| paradoxdCTL/in | Input topic |

| paradoxdCTL/hassio/Arm/zoneX | Gives values ON/OFF |
| paradoxdCTL/hassio/Arm | Gives values: disarmed, armed_home, armed_away, triggered |
Sending commands
The command payloads are in JSON. Template:
{
"password":"1234",
"Command":"arm",
"Subcommand":"0"
}The password is the user's 4 digit password.
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 | partition |
| bypass | The zone number from 0 to 31 |
| panelstatus | panel data |
| panelstatus | panel voltage and battery data |
