Wake-up light alarm with sunrise effect

I’m fairly new to HA, but I found a possible solution to your issue. The below reference is a way to set the time helper to a timestamp. However, I did also have to use an automation to update_entity at 2:30 each morning.

Using an input helper to update a timestamp sensor

Assuming the input_datetime contains date and time: template: - sensor: - name: whatever device_class: timestamp state: "{{ states('input_datetime.something') | as_datetime | as_local }}" Assuming the input_datetime contains time only: template: - sensor: - name: whatever device_class: timestamp state: "{{ today_at(states('input_datetime.something')) }}" EDIT Correction. Added as_local filter to ensure datetime has timezone information.
