Each feature of the composite will have to become a feature in Gladys — is that what you had in mind?
What’s blocking you in particular?
Yes, that’s exactly what I had in mind, but how exactly do you make the connection between the composite and all these different features?
I’m not sure that this case is already handled in the code; I think it needs to be coded! (I may be wrong, I’m not the creator of the Zigbee2mqtt integration)
That’s why I’m asking for help, because I don’t know how to go about it.
Do you want us to call each other to look at this together?
For this one I don’t have any magic answers, you have to do the work, you know 
Write the code (I’m not a very good teacher as you can see aha)
I figure you don’t have a magic answer and that we have to write the code. But as a beginner in JavaScript development I don’t know how to get started.
Also, yes, we can try to call each other.
No worries, when are you available?
Availability:
- From 4:30 PM to 6:00 PM (today) or at 8:00 PM
- Wednesday evening at 8:00 PM
- Thursday evening at 8:00 PM
- Friday all day
Thank you 
I’ll check and get back to you tonight.
What’s certain is that before 7 PM it’s not possible on any day of the week.
So it will preferably be at 8 PM.
@pierre-gilles thank you for your call.
That should unblock me
Hi @_Will_71, I’m revisiting this topic and I can’t remember whether we ultimately covered this case or not?
To know whether I can close this request or not
Hi @pierre-gilles , to be honest no, I haven’t figured out how to code that part and I honestly haven’t looked at it since.
I only added the ability to send a zigbee2mqtt message in scenes to fill the gap in the meantime
If you want us to call each other, we can 
@Hizo, Here is finally a test image for the woox siren.
Can you try it and give me feedback?
willde71/gladys-test:woox-siren
@pierre-gilles, the PR for the siren
Yes, tested in real life on my end.
It would be good if someone else who owns the siren tested it too.
Hi,
It’s been so long since I last touched my home automation that I don’t remember how to test it
Could you remind me please, I have a few days off, I’m going to try to do a test.
Hello @Hizo
Here is the tutorial:
Hi, thanks Pierre Gilles
So, here is some feedback that I hope is quite complete and clear
Battery: OK
Flash cycle: Doesn’t change anything for me but triggers the alarm.
The widget could be a slide bar as it goes from 0 to 10.
The value is not shared with Zigbee2mqtt.
Decimal duration: Goes from 0 to 10,000
Very difficult to be precise with a slide bar, a direct value widget would be needed (like the one for the flash cycle)
In Zigbee2mqtt the max value is 3,600 and not 10,000.
Stroboscopic flash: Doesn’t change anything for me but triggers the alarm.
The value is not shared with Zigbee2mqtt.
Flash intensity: Doesn’t change anything for me but triggers the alarm.
The value is not shared with Zigbee2mqtt.
Signal intensity: Shows me 1 bar but 5 in Zigbee2mqtt.
Alert mode: Doesn’t change anything for me but triggers the alarm.
The list is good as per Zigbee2mqtt.
The only way to stop my alarm is by setting it to « stop » mode.
The value is not shared with Zigbee2mqtt.
Sound level: Doesn’t change anything for me but triggers the alarm.
The list is good as per Zigbee2mqtt.
The value is not shared with Zigbee2mqtt.
Siren On/Off: Perfect
Average voltage: OK
Did you not plan to manage the alarm volume?
Because in this case, unlike the other parameters, this one really changes something on my alarm XD
When I say « Doesn’t change anything for me », it’s also the case when I trigger the alarm with Zigbee2mqtt, it’s probably because my alarm is very simple.
The values not shared with Zigbee2mqtt are those of the warning block which are not preserved when reloading the Zigbee2mqtt page.
It therefore seems normal that the values do not propagate from one side to the other.
I don’t know what the duration is used for here as there is no difference.
But above all, is it possible to trigger an alarm from a scene?
I haven’t managed to do it, the « control a device » block does not allow executing an action for example.
But maybe I haven’t found the right block.
And this is really the main interest from my point of view
In any case, thanks a lot Terdious for your work!
