Setting a time in dashboard to start the carheater

Hello everyone,

I couldn´t find anything in my 5min search so I open a new topic :grimacing:

I want to have an entrance in my dashboard where I can define a time when my car heating should be finished.
But I can’t find any information to set a specific time in the dashboard.
When I set the time at 13:00 in the dashboard I want it to start at 12:30. Does anyone have similar automation or dashboard function?

An Input Datetime Helper can be used to set a time in the Dashboard. You use it as the trigger for your automation by using a Time trigger

is there a possibility if the time is set to 10:00 to trigger it at 9:30?
