Flow from @Peter_Kawa Device state time logger. It works fine but i can not save a name for the chronograph. I can change it in the flow it self and than it works.

> Device state Time logger (Fixed some logics issues) For how long was my device on or off today (or the last X hrs/days)? The example flow resets the stopwatch at midnight. 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.
