By pausing the stopwatch, when the device status is changed back, the times get added automatically when the device status changed again, until one resets the stopwatch. The duration gets written into 2 variables, one with hh:mm:ss format and one with human time format.

Basically all TEF actually. The TEF’s are loading up fine and i can choose lights and sensor.  
I did however get it to work if i set Chronograph to “Do not change”

Here are some screenshots.

On this screenshot i dont get anything when Chronograph is set to “Create”

Here i change to “Don’t change”  
and now i get a script when i hit “Update Text”

So to me it seems to be a problem with Chronograph?
