Duplicate zone possible

G'day all and g'day Mike

My Konnected Pro/Homebridge setup has been running smoothly since my install and I continue to be incredibly pleased with the way it works.

One feature of our previous Bosch panel that we miss is the 'woop-woop' from our system when armed or disarmed. We usually arm the alarm via a key fob remote (as described here) and we do this from outside the house. 

Ideally, our phone would give us instant feedback that the system was armed - but in practice, this isn't the case. If we're JUST out of wifi range, then it can be a 5-10 seconds before a Home app notification comes through, by which time I've already hit the fob button again, thinking the arming wasn't successful!

So, what I'd like is for the siren/strobe to woop/flash once.

For background, I have two sirens - one is the external siren/strobe box on the front of the house and the other is an internal siren mounted in the roof space. 

I have set up the external siren/strobe on the ALARM 1 output, and the internal alarm on the ALARM 2 output. 

This is my config

{
                            "enabled": true,
                            "zoneNumber": "alarm1",
                            "zoneType": "siren",
                            "zoneLocation": "Siren and Strobe"
},
{
                            "enabled": true,
                            "zoneNumber": "alarm2_out2",
                            "zoneType": "siren",
                            "zoneLocation": "Internal",
                            "switchSettings": {
                                "pulseDuration": 60,
                                "pulsePause": 940,
                                "pulseRepeat": 1
                            }
}

I DO have this working using the internal siren. That's why I have it set to sound for a short time (60ms). To be clear, this works! Unfortunately, when we're outside the house in a running car, we can't hear the internal siren woop. That's why I'd like to use the external siren/strobe.

I tried setting up a new Zone, specifying the Alarm 1 output AGAIN, but this time by setting s short duration for the siren (we don't want it going indefinitely, like it would when the alarm is triggered). In this way, I was hoping to have a separately addressable output that just happens to use the same physical hardware. I see in the logs that this isn't allowed: 

[10/10/2021, 14:01:28] [Konnected] Duplicate Zone: Zone number 'alarm1' is assigned in two or more zones, please check your Homebridge configuration for panel with UUID XXXXXXXXXXXX.

 Could this be allowed in a future update to achieve custom siren/strobe behaviour only in certain circumstances? Or does this fundamentally go agains Konnected's allowed behaviour/function?

You might be thinking "Why not just create an automation in the Home app that activates the siren/strobe for a short time when the alarm is either armed or disarmed?"

Well, that's the first thing I tried. Unfortunately, the Home app doesn't allow a wait command of less than a second and sounding the siren for 1 second is a surprisingly long time when a 100+db siren is going off at 10pm :D

All suggestions or feedback are welcome. 

Thanks again, Mike for all your work in getting Konnected and Homebridge working so well together.
