Send entty_id and state telegram

my automations.yaml file is like this:

- id: '1580730150400'
  alias: Poco Away
  description: ''
  trigger:
  - entity_id: binary_sensor.maindoor
    platform: state
    to: 'on'
  - entity_id: binary_sensor.maingate
    platform: state
    to: 'on'
  - entity_id: binary_sensor.gatestairs
    platform: state
    to: 'on'
  - entity_id: binary_sensor.bathroom_pir
    platform: state
    to: 'on'
  - entity_id: binary_sensor.motion_sensor_158d0002246c35
    platform: state
    to: 'on'
  - entity_id: binary_sensor.sonoff2_pir
    platform: state
    to: 'on'
  condition:
  - condition: state
    entity_id: binary_sensor.pocophone
    state: 'off'
  action:
  - data:
      message: alert {{  trigger.to_state.state  }} + {{  trigger.entity_id  }}
    service: notify.telegram

the automation is triggered, but the message isn’t sent. i think it’s in my syntax. i tried using just the word alert, and it sends. i need to have the entity_id that triggers the automation and it’s state sent also. how do i do this?
Thank you
