HoneywellSecurityMQTT

This project is based on fusterjj's HonewellSecurityMQTT project which was based on jhaines0's HoneywellSecurity. It listen's for events from 345MHz security sensors and sends messages via MQTT.

I attempted for simple event/message translation, but some state/persistance was required to acheive debouncing of signals.

Features

Decodes data from sensors based on Honeywell's 345MHz system. This includes rebrands such as 2GIG, Vivint, etc.
Requires no per-sensor configuration
Decodes sensor status such as tamper and low battery
Reports alarm and sensor status to an MQTT broker
NEW Support for multisensors. For example, a water sensor with high-temp and low-temp alerts.
NEW Support for some 345 keyfobs and 345 keypads.

Requirements

RTL-SDR USB adapter; commonly available on Amazon
rtlsdr library
mosquittopp library
gcc

Installation

Dependencies

On a Debian-based system, something like this should work:

  sudo apt-get install build-essential librtlsdr-dev rtl-sdr libmosquittopp-dev

To avoid having to run as root, you can add the following rule to a file in /etc/udev/rules.d:

  SUBSYSTEMS=="usb", ATTRS{idVendor}=="0bda", ATTRS{idProduct}=="2838", MODE:="0660", GROUP:="audio"

Then add the desired user to the audio group. If you plugged in the RTL-SDR before installing rtl-sdr, you probably will need to do something like sudo rmmod rtl2832 dvb_usb_rtl28xxu then remove and reinstall the adapter.

Configuration

Modify mqtt_config.h to specify the host, port, username, and password of your MQTT broker. If "" is used for the username or password, then an anonymous login is attempted. Also, the payloads of some signals can be configured.

Building

  cd src
  ./build.sh
