Timestamp sensor for Wake-up light alarm with sunrise effect blueprint


I have spend hours on trying to understand how to setup the timestamp sensor for the Wake-up light alarm with sunrise effect. The blueprint is working when setting the timer manually. I would like to use shortcuts app on my iPhone to set the alarm automatically via the calendar. I have enabled the ‘date_time_iso’ and ‘date’ sensors.

I have searched the forum and tried creating different sensors like Using an input helper to update a timestamp sensor and setting the timer from a helper with date and time.

But nothing works… I am not able to get it to work.

Thank you for your help.

Same problem…
