Offset with Input_datetime trigger

I wish there was an option to have a set offset for a input_datetime trigger. It’s possible to have this functionality with sunrise or sunset, so it’s a bit weird this isn’t availible with time input.

I know this is easily doable with a template, but it would still be pretty nice for users who don’t know a lot about templates
{{ now() >= today_at(states('input_datetime.example')) - timedelta(minutes = 30) }}

Thanks for reading my request :slight_smile: Have a nice day

Don’t forget to vote for your own request.

I’m stunned this isn’t already a feature!
