@Emile any comments on this issue?
The top card should work
@ZDrKondler
Unrelated, but it can return unexpected values:
What doesn’t work is firing the timeline card without delay.
You probably assume the top card is fired before the card below, but Homey fires all “Then” cards at once.
To give the logic card time to finish, you’d add a 1s delay to the timeline card.
(a few ms should do, but the smallest value possible is 1s)
Delay doesn’t make any changes. The main problem is the error in the first row. Temp. value isn’t stored in any case 
I"ve tried to explain it’s unrelated to the card going wrong 
But when you want correct results (when the bug is fixed), you’d add a delay to the timeline card
What happens if you create a new number variable with a different name and assign the value?
It’s the same. The variable isn’t stored, and the error says it’s not a number.
