Wildcard in target entity id

Configuration
1

How would I write an automation to automatically update? This is what I have so far though I’m unable to find a way to use a wildcard when specifying an entity id:

update_automatic:
  automation:
    action:
      - data:
          backup: true
        service: update.install
        target:
          entity_id: update.*
    alias: "Update - Automatic"
    id: update_automatic
    trigger:
      - at: "00:00:00"
        platform: time

Templating

update_automatic:
  automation:
    action:
      - data:
          backup: true
        service: update.install
        target:
          entity_id: > 
            {{ states.update | selectattr('state','eq', 'on')
            | map(attribute='entity_id') | list }}
    alias: "Update - Automatic"
    id: update_automatic
    trigger:
      - at: "00:00:00"
        platform: time

Is there anyway to detect if an entity supports backup? I receive an error for ESPHome devices.

Backup is not supported for Firmware

Looking at the expanded state object, it seems to include each supported feature’s title, so you should be able to use:

{{ states.update | selectattr('state','eq', 'on')
| selectattr('attributes.supported_features', 'search', 'BACKUP') 
| map(attribute='entity_id') | list }}

Just FYI, make sure your backup methodology is as reliable as possible before auto-updating without checking breaking changes.
