Condition template for automation with state_changed as trigger

Configuration
1

I want to add a condition so that the automation only triggers if the sensor belongs to a certain integration (mqtt), is it possible? How can I do it?

alias: Teste bateria
description: ""
trigger:
  - platform: event
    event_type: state_changed
condition:
  - condition: template
    value_template: >-
      {{trigger.event.data.new_state.attributes.device_class | default('') ==
      'battery' and
        trigger.event.data.new_state.state < '9'}}
action:
  - service: notify.mobile_app_sm_g985f
    data:
      title: Dispositivo Zigbee com bateria baixa
      message: "{{ state_attr(trigger.event.data.entity_id, 'friendly_name')\_|\_capitalize\_}} em {{ trigger.event.data.new_state.state}}%"

This automation will trigger on every state and attribute change of every entity… do not use that trigger. It’s inefficient, will likely be unreliable, and difficult to debug.
