[Feature]: Get entity values such as name or icon in Template card

[ov1d1u]

Requirements

• [X] I have updated Mushroom to the latest available version
• [X] I did a search to see if there is a similar issue or if a pull request is open.

Is your feature request related to a problem?

I know that I could use {{ state_attr('switch.entity_id', 'icon') }} for icon in a template card, but this requires a request to the HA backend (which causes some rendering issues) and it doesn't return an icon reflecting the current state of the entity. It would be nice to directly reference the entity icon (and other things, such the entity's name) in the template card fields.

Describe the solution you'd like

I'm not sure how the best solution would look here. I made an implementation here for my personal use which detects if the icon value is not a template and contains a . (dot) and if it does, it uses stateIcon with that value. I know it is a stupid solution (I just discovered this project yesterday so I'm not really experienced with the code) so something better needs to be designed. I'm not primarily a TypeScript developer, but I'm willing to contribute with a solution.

I have an issue that is very close, trying to built a weather mushroom card using either entity or template card (I want it bigger that the wonderful weather chip...)

• I can have a nice card with good icon with the entity card, but I cannot display the temperature or wind or alert (I would need a templated second line)
• I can display all information I want with the template card, but I am not able to recover the default icon from the entity.

This would be a great feature as I also frequently find myself resorting to using icon: "{{ state_attr(entity, 'icon') }}". I find that this doesn't always work though as some entities don't appear to expose an icon attribute. In particular I'm having problems with a weather entity. It would be great if the card could behave more like the Mushroom Entity card when not using a template value.

Along the same lines, I have trouble with the entity state using the Template card, again with a weather entity. If I have something like secondary: {{ states(entity) }} it might display partlycloudy rather than Partly Cloudy, as it would appear using the Mushroom Entity card.

For the icon, options I can think of might include:

• Have the default icon be the state icon as it is in the Mushroom Entity card, however, this would affect existing cards. You'd need to specify something like icon: None to hide the icon. To be consistent with the Entity card I suppose you'd specify icon_type: none instead.
• Do something like the OP has done by checking the value is not a template and either contains a "." (period) or does not contain ":" (colon), as in "mdi:". This does mean you'd have to duplicate the entity name again, as in icon: sensor.xyz. The entity may already have been specified under entity: sensor.xyz, although this would allow you to reference a different entity if desired. It might be nice (and consistent) to allow any of icon: entity (which references the card's entity) or icon: sensor.xyz.

Do something similar for the primary: and secondary: values:

• If not using a template, allow primary: entity or primary: sensor.xyz to be specified, which would display the regionalized entity state string as occurs with the Mushroom Entity card.
• Alternatively, if not specifying a template then just behave like the Entity card and allow options like name, state, none, etc. to be specified.
