Hello and welcome, Dexter,
In most triggercards, you can’t use a variable as value, but as you’ve noticed, there’s no warning and the card can be saved.
I prefer to use a Chronograph timer:
- You can use a numeric variable as timer value
- It survives a power outage / Homey restart
Example
.
Not to my knowledge. You happen to have used an invalid input method.
Pls write to Athom support why there’s no warning / why you can save the card (homey.app/support).
