Blueprint: use !inputs (or variables) in templates

Just wanted to say your edit in your comment helped me solve my frustration. Never knew Trigger Variables existed! Many thanks.

Hi I’m trying to create a blueprint that has a input named remote_id of type text , how can I use the input in a condition?
{{ trigger.event.data.id_string.startswith( states(remote_id) + ':') }} does not seem to match the event data correctly?

blueprint:
  input:
    remote_id:
      name: Remote id
      selector:
        text:

variables:
  remote_id: !input remote_id

trigger:
  - platform: event
    event_type: rfxtrx_event

condition:
  - condition: template
    value_template: "{{ trigger.event.data.id_string.startswith( states(remote_id) + ':') }}"

event:

remote_id: 1599e6a
all_off_action:
  ...
1_on_action:
  ...
1_off_action:
  ...
2_on_action: []
2_off_action: []
3_on_action: []
3_off_action: []
this:
  entity_id: automation.sovrum_fjarrkontroll
  state: 'on'
  attributes:
    last_triggered: null
    mode: single
    current: 0
    id: '1679664439381'

    parent_id: null
    user_id: null

      parent_id: null

  description: event 'rfxtrx_event'

What am I doing wrong here?
The remote_id is specified as 1599e6a and trigger.event.data.id_string is 1599e6a:1, so why doesn’t {{ trigger.event.data.id_string.startswith( states(remote_id) + ':') }} match the event?

The full source of the blueprint can be found here

I didn’t understand what states() did, but removing it and just using remote_id solved my issue

Hello,

You are very close. The only change you need is to use a different name for the input variable in the blueprint section. One may apply an input_ prefix to the variable name as follows.

blueprint:
  input:
    input_alarm_trigger:

variables:
  alarm_trigger: !input input_alarm_trigger

trigger:
  - platform: template
    value_template: "{{ states('alarm_trigger') == true }}"

Placing the variables under the variables: OR the trigger_variables: stanza worked for me.

I feel like this should be better explained in Blueprint Entity Selector Tutorial.

Thanks to @bverkron for finding and @joshcrosby for pointing it out after I skimmed passed it.

kristofferbas I am rewriting it here, so people coming off the Google train don’t have to read so much, in-case you want to mark it as answer.

P.S.
I think trankillity is correct in stating that the rendering engine should be able to handle this. If technically feasible, a input() Jinja call, in addition to states() would make this work-around not needed.

This is a very old post, but I think I need to set it straight.
The name as long as it is valid doesn’t matter. What you show @vittorio88 will not work.
If you want to put a variable into a trigger, it has to be built using the trigger_variables: key.
This is because that key is rendered when you save the automation (or blueprint) and will exist for the trigger to use.
Variables:, no matter where they are in the automation (or blueprint) are rendered after the trigger and do not exist before, so when put in the trigger are probably ‘unavailable’ or ;null’ or something.
This is also why template_triggers: are limited in what they can do as they only have access to some of the jinga and only information available when the automation (or blueprint) is saved. They know what the !inputs are, so that works fine. Not a lot beyond that.
The documentation is covered here:
Automation Trigger - Home Assistant.

(PS, pinging people years after they posted something is not a great idea. )

Hi All,
I want to make an automation firing every 10 -20 seconds and do the following:

  • When max_cell_voltage is above the protected_max_cell_voltage
  • Reduce the max_charge_current by 1
    The problem is max_cell_voltage is a sensor and returns a string represents a float value (such as 3.124) while protected_max_cell_voltage is an integer.
    The automation does not run and throws the following error: “Stopped because a condition failed at October 3, 2024 at 7:08:30 PM (runtime: 0.00 seconds)”.
    Can anyone be so kind to help me with thanks.
variables:
  target_var: number.homehna_charging_current_max
  input_condition_var: sensor.homehna_max_cell_voltage
trigger:
  - platform: time_pattern
    seconds: /10
condition:
  - condition: numeric_state
    entity_id: sensor.homehna_max_cell_voltage
    value_template: '{{ states(input_condition_var) | float * 1000 | int }}'
    above: number.homehna_over_voltage_protection
action:
  - action: number.set_value
    metadata: {}
    data:
      value: '{{ states(target_var) | int - 1 }}'
    target:
      entity_id: number.homehna_charging_current_max
