Mate, you fixed my issue with the original blueprint. Well done!

thanks, this also solved an issue I had with time zones/summer winter time

Thanks for this. I have one minor issue in that it fills the logs with messages like the below, obviously not an immediate issue:

2025-02-11 07:29:57.023 WARNING (MainThread) [homeassistant.components.light] Got `color_temp` argument in `turn_on` service, which is deprecated and will break in Home Assistant 2026.1, please use `color_temp_kelvin` argument

Hi @lnlyssg, I modified the two spots in the blueprint that were using color_temp, and replaced them with color_temp_kelvin. I haven't tested it out, so if you have a chance, please kick the tires and let me know if it worked.

Working perfectly thanks!

Hi @triplepoint, is there an Option to Implement an other Time Class? Something like:

      selector:
        entity:
          domain:
          - input_datetime

I would like to use a helper to set an time value instead of an device_class: - timestamp

Yeah that's what I've done, I updated the input like this:

    timestamp_sensor:
      name: Alarm timestamp sensor
      description:
        "Datetime helper with timestamp of next alarm or set to 'none' for manual alarm time"
      default: none
      selector:
        entity:
          filter:
          - domain:
            - input_datetime

I replaced the "timestamp_sensor" with your code and restarted home assistant. Sadly it's not starting the automation. Did you change something else in the code? Ad additional check, i use an input_boolean helper.

@Edocsyl Probably... I made quite a few changes to it so just stuck everything in my own gist at https://gist.github.com/lnlyssg/65e47876a767385e331300d440404a31 if you want to take a look and compare
