Hello, I can not get this alarm card to trigger when I am using tags. If I write 1 minute in the card it works, but if I make a tag called “Duration” with a “1” then it does not work. How come?
That’s correct, it is a limitation or known issue
But probably wil not be fixed.
You could ask Athom support for it.
Well this is a major problem! How is a small bug like this not prioritized to be fixed? Where do I report a complaint?
I have an engine block heater that needs to run for a variable amount of time based on the outside temperature. So I want to set the pick up time as an alarm and have the start time be calculated based on the temperature. How do I do that if I can not set the alarm with tags, and I can not pull the DateTime value of the alarm to use in some other logic?
Not at the community… you could try https://homey.app/support/
If that gives you a good feeling.
But I guess you better work to a flow that doesn’t need this tag in the trigger.
Workaround:
I assume you already have an algorithm that calculates the number of minutes needed to preheat your engine depending on outside temperature . Let’s say X minutes.
Set an alarm ‘ time to leave home’ for the time you want to leave home.
WHEN
Alarm ‘time to leave home’ goes off in 60 minutes.
THEN
Start timer ‘preheating engine’ with runtime {{60-X}} minutes.
WHEN
Timer ‘preheating engine’ ends
THEN
Start preheating engine

As workaround, the Timey app can trigger flows with the time set by variables/tags:
In our country we say “Where can I send an improvement proposition” instead
