Hi Ranney

You can do it like this:  
Create a numeric variable, I called it `dryer_remaining_minutes`

The tag [`dryer_remaining`] represents the tag from your dryer, which should be a string(text) tag (right?)

You can view the result from the Timeline card next to it in the Timeline Viewer

(All cards are ‘Then’ cards)
