Alarm with calculated attributes

Hi,

I don't quite understand how to create an alert with a calculated attribute. In the example in the picture I created an "AlarmDoors" attribute of type alarm. I would expect to see it in the drop down menu of the notification screen, but it doesn't.
How do I get an email when the alarm occurs?

You can't define new types for alerts. You have to use one of the existing ones.

So it's impossible to create a custom notification?
for example if i want to receive an email if input1 < of 1000, there is no way?

You can create a notification for it, but you have to use one of the existing types.

Thanks Anton, I think I got it!
