Good input. I haven’t even thought about that 
So, we can note down that I am luckily not the only smart person here 
Seriously, @rockit4, what is the technical limitation? The iOS and android apps are showing the alarm. As far as I have understood, the binding builds up one the same API…
Thanks and
Best, Lui
I can only guess as I am not developing this binding. But the app is probably using push to send the message immediately to the client, but this binding collects information at the set time interval.
I think @FlorianSW knows 
But if I remember correctly he doesn’t even own any Ondus device so the development of this binding is understandably not prioritized.
I installed the binding, account goes ONLINE
The scan brings up the Guard + 3 sensors
The sensors go online, but the Guard thing reports
HANDLER_INITIALIZING_ERROR
Cannot invoke "java.lang.Integer.intValue()" because the return value of "io.github.floriansw.ondus.api.model.guard.Config.getMeasurementTransmissionIntervall()" is null
Is there a fix? Anything else I could change?
