All,

Here is a script I put together to take RF events and system events and push them to openHAB. I have also included corresponding samples from the openHAB item file and the translations used.

It should be a fairly simple to change this to monitor zones instead of RF devices, but I want to monitor RF contacts that are not configured in my panel.

If you have any questions or run into issues, please let me know.

Cool stuff! I went ahead and added openHAB and your repo to our list of supported home automation systems. Thanks!

Hi, thanks for putting this together. Will this script work with the AD2Pi or just the USB version?

Looking at the code it looks to target USB devices, however it could be modified to be used with the AD2Pi

in ad2openhab.py

If you want from the raw serial port of the AD2Pi:
FROM

Code: Select all

from alarmdecoder.devices import USBDevice

# Global Variables
LOG_FILE = '/opt/ad2openhab/messages'
OPENHAB_HOST = 'localhost'
OPENHAB_PORT = '8080'

def main():

    try:
        # Setup logging
        logging.basicConfig(
            filename = LOG_FILE,
            level = logging.INFO,
            format = '%(asctime)s %(message)s',
            datefmt = '%m/%d/%Y %H:%M:%S'
        )

        # Retrieve the first USB device
        device = AlarmDecoder(USBDevice.find())

        # Set up an event handler and open the device
        device.on_rfx_message += handle_rfx_message
        device.on_arm += handle_arm
        device.on_disarm += handle_disarm
        with device.open():
            while True:
                time.sleep(1)


TO

Code: Select all

from alarmdecoder.devices import SerialDevice

# Global Variables
LOG_FILE = '/opt/ad2openhab/messages'
OPENHAB_HOST = 'localhost'
OPENHAB_PORT = '8080'

#default AD2Pi device on Raspberry Pi
SERIAL_DEVICE = '/dev/ttyAMA0'
BAUDRATE = 115200

def main():

    try:
        # Setup logging
        logging.basicConfig(
            filename = LOG_FILE,
            level = logging.INFO,
            format = '%(asctime)s %(message)s',
            datefmt = '%m/%d/%Y %H:%M:%S'
        )

        # Retrieve the Serial Device
        device = AlarmDecoder(SerialDevice(interface=SERIAL_DEVICE))

        # Set up an event handler and open the device
        device.on_rfx_message += handle_rfx_message
        device.on_arm += handle_arm
        device.on_disarm += handle_disarm
        with device.open(baudrate=BAUDRATE):
            while True:
                time.sleep(1)


Or if you are using Ser2Sock:
TO

Code: Select all

from alarmdecoder.devices import SocketDevice

# Global Variables
LOG_FILE = '/opt/ad2openhab/messages'
OPENHAB_HOST = 'localhost'
OPENHAB_PORT = '8080'
SER2SOCK_HOST = 'localhost'
SER2SOCK_PORT = 10000

def main():

    try:
        # Setup logging
        logging.basicConfig(
            filename = LOG_FILE,
            level = logging.INFO,
            format = '%(asctime)s %(message)s',
            datefmt = '%m/%d/%Y %H:%M:%S'
        )
        # Retrieve an AD2 device that has been exposed with ser2sock on localhost:10000.
        device = AlarmDecoder(SocketDevice(interface=(SER2SOCK_HOST, SER2SOCK_PORT)))

        # Set up an event handler and open the device
        device.on_rfx_message += handle_rfx_message
        device.on_arm += handle_arm
        device.on_disarm += handle_disarm
        with device.open():
            while True:
                time.sleep(1)


Thanks for the quick reply Kevin!

Do you recommend one protocol vs the other? I am new to this.

If you are using Ser2Sock with our AD2Pi raspbian image, it gives the ability for multiple devices to interface with the AlarmDecoder products over TCP/IP. I think this is the preferred method unless you have something prohibiting it.

Can you tell me where this file should be located? I am using your Raspberry image and have successfully connected to my panel but I am not sure if the Python interface is already installed or if I need to install that first. I can get around but definitely a novice.

Thanks!

According to his source, everything is in /opt/ad2openhab/

But realistically, you could run it from anywhere provided you are using the correct device type - if you are using our image, you would want to make sure that it is a socket device, as that is the only way to have multiple applications speak to the alarmdecoder device at the same time.

You would just execute python ad2openhab.py from a shell, or modify an init script to start that automatically on boot (after ser2sock of course).

Thanks,
Kevin

Thanks Kevin. Really appreciate the quick replies!

How do I determine if this is a socket device?

You said you were using our Raspberry Pi image? Try and telnet to the IP address Port 10000 - if you can connect and see alarm messages, you are a socket based device.

Thanks,
Kevin
