Describe the enhancement

Some of the device types like binary_sensor expose the attributes map which is very useful for adding additional details. It would be great if the lock device type could support that as well. Or even better if all devices classes could support it.

p.s.: Many thanks @Petro31 for all your recent enhancements. I absolute love the Template integration, not sure how I would live without.

Use cases

Here is an example for a lock that computes its state based on whether the door is actually closed and exposes the door status in an additional attribute:

- lock:
  - name: Main door
    state: >
      {{ is_state('lock.main', 'locked') and is_state('binary_sensor.sonoff_door_main', 'off') }}
    lock: 
      action: lock.lock
      target:
        entity_id: lock.main
    unlock:
      action: lock.unlock
      target:
        entity_id: lock.main
    attributes:
      door_status: "{{ 'Closed' if is_state('binary_sensor.sonoff_door_main', 'off') else 'Open' }}"

With that, it would be very easy to show additional data in a dashboard

type: tile
entity: lock.main_door
icon_tap_action:
  action: toggle
name: Main
state_content:
  - state
  - door_status
