Hi all!

I’m busy with Heimdall setting up an alarm. I’d like to play a sound and blink lights until the alarm is disarmed of a specific time in example 60 minutes. What is the best practice to set this up?

Thanks in advance.

I would create a transition with the chronograph app ‘alarm triggered ‘ with duration 60 minutes en 3600 steps. When the transition is started it will reach a step every second.

So:

WHEN alarm is triggered THEN start transition ‘alarm triggered ‘

WHEN transition ‘alarm triggered ‘ reaches a step THEN play sound and switch desired lights

WHEN alarm is disabled THEN stop transition ‘alarm triggered ‘
