[Help]: Is there a way to send an z-wave Alarm Cancellation Message ?

How can we help?

First off, Awesome project. I first used the OpenZWave implementation but this is so much better.
So I have not used my zwave nodes like lights, dimmers etc. as alarm nodes. This because I do not know how to cancel a wave alarm. I know it is possible for zwave nodes to send and/or receive an alarm cancellation, but if I want to create my own manual switch for this (for example via the node-red Dashboard UI), I do not know what type of message to sent.
Anyone got any ideas on this ?

Any more details?

HI @dionmes ,

Are you referring to a z-wave siren of sorts?
we first need to define what your 'alarm' is, is it a z-wave siren of some kind?

or are you using your z-wave lights as a strobe of some kind?
I use a z-wave siren, and controlling it is a breaze.

I would also update to 6.2.0 - this has some killer features that allows to streamline all your commands with incredible ease!

Hi Marcus, going to update this weekend. So the Alarm I am talking about is the specific Alarm Command Class (0x71). A node can generate such an alarm, such as a door sensor or motion sensor, and if I understand correctly this will be broadcasted. And nodes configured to receive this command class like lights and other will respond (like lights connected to a Fibaro zwave switch which will start blinking) . You can see this in the z-wave device configuration.
So I am able to trigger the Alarm via a sensor, and devices will respond, but I do not know how to send an Alarm Cancellation Messages (so these lights will stop blinking, Siren will stop sounding etc.).

So,

The CC 0x71 and the Reference to Alarm was deprecated by Zwave Alliance quite some time ago.
0x71 is now called Notification - and its used for many types of notifications.

There are 1000 ways to achieve what you want: Easy -> Not So Easy

NOTE: I am creating the commands manually here, but the new CMD-Factory (6.2.0) - will construct them for you.

Triggering:

1. Just listen for your door being opened or motion being triggered within Node-Red
   • When that happens - send a command to your lights (presumably they have a flash function?)
   • If your lights depend on a notification, send the expected event and type they want, in order to trigger said strobe.

  {
       "mode": "CCAPI",
        "cc": "Notification",
        "method": "sendReport",
        "params": [
             {
                "notificationType": 7, /* Home Security */
                "notificationEvent": 1 /* Intrusion */
             }
         ]
     }

2. Use Associations
   Whilst this works, both devices needs to support each others output messages
   you will use the UI to set this up - it can be very simple or extremely annoying - really depends on your devices

Stopping:

If Using 1:
just send the commands to stop everything (usually the Binary CC) - but it depends on the devices
and if your lights need a notification to stop

  {
       "mode": "CCAPI",
        "cc": "Notification",
        "method": "sendReport",
        "params": [
             {
                "notificationType": 7, /* Home Security */
                "notificationEvent": 0 /* Idle */
             }
         ]
     }

I am using Home Security - but there are loads

If Using 2:
I would have thought the associations would take care of this

How I do it (I only have a siren):

When my motion is triggered I send this to my siren

  {
       "mode": "CCAPI",
        "cc": "Notification",
        "method": "sendReport",
        "params": [
             {
                "notificationType": 7, /* Home Security */
                "notificationEvent": 1 /* Intrusion */
             }
         ]
     }

when I want to stop the alarm, I send this (but I could use idle in a notification - but have never really tried it with my siren).

    {
         "mode": "CCAPI",
          "cc": "Binary Switch",
          "method": "set",
          "params": [false]
       }

What notification types/events you devices support will be in their manual, as well as there supported CC's obviously.
