How to create an entity to call a service with data

Configuration

Hi, I have an widget on my watch which allows you to call entities in a group. What I’m trying to achieve is call a service and pass the vin data to this service to start my car. In order to do this I need to create an entity that calls the service and passes the data. This entity can then be added in the group. Then all I have to do is navigate to this widget on my phone and I can start my car.

The problem is that I have no idea how to create an entity to call a service with data. I’m not even sure if this is possible. Does anyone have any ideas?

Disregard, I figured out how to do it. I didn’t realize you could just create a script and it acts as an entity that you can add to groups. It works awesome.
