Script Blueprint: Apply action when condition is met

Configuration Blueprints

For the life of me I can’t figure out why an action won’t work when my condition is met. I have an action to turn a pump on, and when the condition (where tank volume >= water volume target) is met, it should turn the pump off.

I have checked with the debugging template and the condition is working

area of code I’m having issues with:

# Fill Nutrient Tank
  - action: switch.turn_on
    target:
      entity_id: '{{fill_tank}}'

  - condition:
    - condition: template
      value_template: >
          {% set waterVolume = states('input_number.water_volume') | float %}  
          {% set tankVolume = states(tank_volume) | float %} 
          {{ tankVolume >= waterVolume }}
  - action: switch.turn_off
    target:
      entity_id: '{{fill_tank}}'

Conditions are not Wait actions… if the condition isn’t true the moment it is checked then the script stops at that point.

Sometimes feel a little silly not thinking of it! Thank you very much, that solved my issue:

  - action: switch.turn_on
    target:
      entity_id: '{{fill_tank}}'

  - wait_template: >
          {% set waterVolume = states('input_number.water_volume') | float %}  
          {% set tankVolume = states(tank_volume) | float %} 
          {{ tankVolume >= waterVolume }}
  - action: switch.turn_off
    target:
      entity_id: '{{fill_tank}}'

FWIW, you can use inputs directly when they provide the type of value you need, you don’t have to use script variables. You only need to use script variables if you need to use the value in a template.

In your example snippet, you can use !input fill_tank instead of '{{fill_tank}}' to supply the entity ID’s.

  - action: switch.turn_on
    target:
      entity_id: !input fill_tank
  - wait_template: >
      {% set waterVolume = states('input_number.water_volume') | float(0) %}  
      {% set tankVolume = states(tank_volume) | float(0) %} 
      {{ tankVolume >= waterVolume }}
  - action: switch.turn_off
    target:
      entity_id: !input fill_tank

Thanks for clarifying that. I was aware of this but for one reason or another things weren’t working and so I do the usual of tweaking things here and there without fully knowing what I’m doing. Still learning when it’s appropriate to set a variable and when it’s not needed etc, which I’m pretty sure you’ve explained in a previous post. Thanks again for all your help
