How to reset a input.datetime as a service-call

what am I doing wrong?

Using templates in Lovelace. Pretty much only the markdown card supports that.

Call a script that resets your helper or use this custom card and JavaScript templates:

100% Templatable Lovelace Configurations

Lovelace Templates I’ve gone and made a crazy card that allows you to pretty much template anything in Lovelace for your card configurations using any information available on the frontend; states, attributes, user, etc. Want state/attribute-based icons? DONE! Want dynamic stacks; vertical vs horizontal based on user? DONE! Want OR conditionals? DONE! The list is pretty much endless and I’m sure you all will come up with some crazy stuff. Be sure to share. Go nuts! Enjoy!
