Any advice on how to create a group of device that are just state home?

In the interface? If so, look at the conditional card.

Simply create a group.location and add all the location sensors you have.
If any one of them is “home” the whole group will be home.
If all of them are “not_home” the group will be not home.

# Templates

The `templates` attributes allow you to inject your own expressions and code using JavaScript code or template literals in order to override entity attributes and state. Within the code / template literals, you have full access to the entity's state object, which allows you to access other properties such as last_changed, attributes.friendly_name, etc. The full set of objects available is shown below.

Additionally, `extra_data_template` attribute is always evaluated as a template without using `templates` attributes for it.

In order for a template to return "nothing", for example so that `extra_data_template` won't take space or allow showing `show_last_changed` - return `null` from your template. Note that `null` can only be returned using code format, as template literal format always returns a string.

**Note that those are JavaScript templates evaluated in your browser, not Jinja2 templates which are evaluated server-side and use a different syntax.**

### Available variables
#### Global variables
Those variables allow one entity to set state / attribute based on another entity or some other "external" thing. Using those hurts UI performance, so use them only if you indeed want an entity to depend on something external.

`hass` - the hass object

`entities` - a map object from `entity_id` to state objects.

#### Local Variables
`entity` - the state object for the current entity.

Got it, that did the trick. Just gotta test it to see if it updates.

Works perfect and keeps up to day too. This is exactly what i was looking for.

You need custom ui

Create a group with no entities

homescreen_dash_whoshome:
  name: "Who's Home"
  control: hidden

Then under customize

group.homescreen_dash_whoshome:
  custom_ui_state_card: state-card-custom-ui
  templates:
    entity_id: "return Object.keys(entities).filter(key => entities[key].state === 'home' && key.startsWith('device_tracker') )"

custom-ui is for the old interface.

Homeassistant now uses lovelace for it’s interface.

For lovelace you just use a conditional card, as per my original reply.

You should upgrade your system.

Im on 84 don’t feel like moving all my custom stuff to LL.

Maybe you can share how you would handle it for lovelace users.
