Could you provide a simplest possible example?

The example leaves me confused. Could you please provide an example for creating a template of the entity_card card and deploying it with one single entity? No mushroom card, stack_card, or other custom cards. Thank you!

I have the same issue. I don't know what code to write to get the templated card to display in other dashboards. In my case I have the template /lovelace-templates/example with the the card:
type: entity
entity: sensor.time
what is the simplest code to get this to be displayed on an empty view?

[stefanschaedeli]

just add a manual card with
template: example

This card will now create an error, which you can ignore for now.

Create anoter card (same view or somewhere else) with following card:
- type: custom:linked-lovelace-ui

next click the update all button on this card.

It should have now updated the first card we created

Hey! I'll do this soon!

I added a new card that helps you identify existing templates you can use, as well as what template data you can pass into it.

Although it's not documented anywhere... yet, you can pass data to a template card by surrounding anything with $ so
a template card of

type: markdown-card
name: '$name$'

would create a parameter of

template: demo
template_data:
    name: 'whatever you want'

To make sure you aren't blocked on implementing your templates, here is a Starter Template Dashboard that can be dropped into your own HA instance.

I should also note, the reason for the vertical stacks is because a template is limited to a View that has exactly one card. If there is more than one card on the view, I can't keep track of which one should be the template
