Ad2usb from a serial port, what to do ?

[PPz1961]

I'm a newbie here. I can work a little bit with node-red and I try to obtain messages from my ad2usb unit.

installed NR + serial and ademco palette: OK my computer has a functionnal com3 port working (when plugged the usb cable from ad2usb) on a flow, I added the node com3 input and set at 9600,n,8,1 (connected) connected to this a node com3 request (connected)

I imported the function (labeled as Ademco messages), that begins with "var partition = msg.payload;", etc the ademcolistener node is set to report All data the Ademcostatus is set to Partition1 (because my Vista honeywell unit has 1 partition)

After this, I'm lost. I don't know how to connect all those nodes together and add the proper functions, etc to obtain valid messages

I hope you will read this message ! Thank you

This flow connects the AD2USB / ADSerial Hat to my network mostly via MQTT to spread the load across multiple hosts.

The Serial Hat from the AD2Serial and Pi2 does have some glitches, if the pi is busy it may get corrupt messages (Nightly upgrades do this) and I get notices of the Partition 2 going from ARM AWAY to ARM STAY and back again. I think if I upgraded that back to a Pi3 or Pi4 with more memory this would go away. the USB version from AD2USB never gave me issues until a lightning strike of the barn that fried it.

You can also control the Panel from NodeRed, You need to encode a passcode into it, but it can send the same keypad values back to the panel to change states.

Thank you for the explanation. However, when I try to import this flow, I obtain a syntax error (see screen capture). I'm using node-red v 16.13.2 on a Windows 10 computer (I just set because normally my node-red is working on a NAS machine).

Any idea ?

Looks like GitHub isn't escaping the JavaScript in the JSON, try \"\" in that location. (Quotes should be escaped when embedded by... Quotes.

[jlong23]

// Content in the first Flow outside JSON

var partition = msg.payload;

if( partition !== undefined ) { var alarmText = "";

// Format for core alarm State
alarmText += "Partition ";
alarmText += partition.partitionNumber;
alarmText += " is ";
var alarmState = "";
switch ( partition.systemState ) {
    case 0:
        alarmState += "DISARMED";
        break;
    case 1:
        aalarmState += "NOT READY";
        break;
    case 2:
        alarmState += "DISARMED READY";
        break;
    case 3:
        alarmState += "ARMED AWAY";
        break;
    case 4:
        alarmState += "ARMED STAY";
        break;

    alarmText += partition.messageLine1.trim();

    alarmText += partition.messageLine2.trim();         
}

msg.payload = alarmText;

// Route the Messages to the correct output
