How to get the state attr from a device_id?

Configuration Blueprints
1

Hi, I try to get the current volume of a media_player entity. But in the Blueprint I only get the device_ID not the entity_id. Is it not possible to get the state or attributes from a device_ID?

There’s no link between devices and entities in templates.

3

So there is no way to get the state or attribute of the selected media_player?

4

You’d have to see if that information is contained in the trigger event data.

5

Can you show me an exaple please?

6

Uh, events don’t have examples. You have to look at the data yourself.

subscribe to this event and try and find the info

- platform: event
  event_type: deconz_event
  event_data:
    device_id: !input 'remote'
