Automation triggered, but service: alarm_control_panel.alarm_disarm not really executed

Configuration
1

Automation is correctly triggered
All actions are logged as executed (both in automation log and general log)
Last action “service: alarm_control_panel.alarm_disarm” not really executed (also logged as executed)
If I trigger the automation manually all is executed correctly.

I’m lost in this. Checked and checked again…
Thank in advance

Here the automation code:

Hi katangus, welcome to the forums.

Does your alarm need a code to be disarmed?

Hi,
thank you!

no, code is not needed.

4

To be sure: The alarm has been armed, the automation is triggered, but the alarm won’t be disarmed, right?

5

Exactly.

But the very strange things is that if now I trigger r automation manually the alarm is disarmed.
In all the situation I got all the notification defined

Thanks

This is intended; basically, the manual triggering should work.

Is the service alarm_control_panel.alarm_disarm working, when you call it in the Developer Tools or in a most simple automation?

7

Yes, both.

Can you please add a delay of let’s say 10 seconds between service: notify… and service: alarm… ?

no changes

Can you try reducing the action: to just the disarm service call and try it.
