Automation error trigered

Configuration

Hi,

I am new to the world of automation, so be patient with me. :wink:
I am trying to send a notification if any temperature sensor has a value less than the default or preset value of my input_number.tempint entity, but I have this error in the LOGS view:

Error while executing automation automation.notificar_temperatura_interior. Error rendering template for call_service at pos 1: UndefinedError: 'trigger' is undefined

id: '1548707669979'
  alias: Send Temperature Int
  trigger:
  - platform: template
    value_template: '{{ (states.sensor.netatmo_salon_temperature.state|float ) <= (states.input_number.valor_tempint.state|float ) }}'
  - platform: template
    value_template: '{{ (states.sensor.netatmo_papas_temperature.state|float ) <= (states.input_number.valor_tempint.state|float ) }}'
  - platform: template
    value_template: '{{ (states.sensor.netatmo_dani_temperature.state|float ) <= (states.input_number.valor_tempint.state|float ) }}'
  - platform: template
    value_template: '{{ (states.sensor.netatmo_aina_temperature.state|float ) <= (states.input_number.valor_tempint.state|float ) }}'
  condition: []
  action:
  - data:
      message: "The temperature of sensor {{ trigger.to_state.name }} is {{ state_attr(trigger.entity_id, 'state' }} 
    service: notify.telegantoni

and I like add the value of the sensor too…

What am I doing wrong?

Thks!

Sorry I’m not great at yaml automations
Prefer node red.
From what I can see
You message statement is where your errors are
trigger.to_state.name ? does that even exist ?
Also you missing ) at the end of state_attrib()

You can’t use trigger.to_state with a template, because if the template triggers it will not give you the entity id, because there is no entity that triggered the automation.

ok, thanks @Burningstone, do you know how I can do it?

I can’t believe it !!, in the end it worked for me with this automation:

- id: '1548707669979'
  alias: Notify Temperature Int
  trigger:
  - platform: template
    value_template: '{{ (states.sensor.netatmo_salon_temperature.state|float) <= (states.input_number.valor_tempint.state|float) }}'
  - platform: template
    value_template: '{{ (states.sensor.netatmo_papas_temperature.state|float) <= (states.input_number.valor_tempint.state|float) }}'
  - platform: template
    value_template: '{{ (states.sensor.netatmo_dani_temperature.state|float) <= (states.input_number.valor_tempint.state|float) }}'
  - platform: template
    value_template: '{{ (states.sensor.netatmo_aina_temperature.state|float) <= (states.input_number.valor_tempint.state|float) }}'
  condition: []
  action:
    service: notify.telegantoni
    data_template:
      message: "Notify of sensor {{ trigger.to_state.name }} is: {{ trigger.to_state.state }}"

Thank you very much everyone!

What you have are valid templates, but there are better ones.

If you use this form:

value_template: "{{ states('sensor.netatmo_salon_temperature')|float <= states('input_number.valor_tempint')|float }}"

Instead of this:

value_template: '{{ states.sensor.netatmo_salon_temperature.state|float <= states.input_number.valor_tempint.state|float }}'

Your template will not generate errors when the entity is unknown or unavailable. See the warning in baby vomit yellow here: https://www.home-assistant.io/docs/configuration/templating/#states

Great change! Thank you very much! @tom_l
