Blueprint+Automation with template trigger and trigger_variables does not trigger

Configuration

1

Hello, I’m trying to create a blueprint with trigger_variables and a template trigger. However, the trigger is never fired. I tried setting the states of the entities used in my automation, and while the developers show true/false respectively, the trigger never fires. Is this not supported?

Developer Tools / Template

This is the template I used in the developer tools that shows the correct true/false outcome:

{{ ((states('sensor.storage_humidity')|float(0) < (states('sensor.e01_tf_humidity')|float(0) + 1|float(0))) and
(states('sensor.storage_temperature')|float(0) < (states('sensor.e01_tf_temperature')|float(0) + 0.5|float(0)))) }}

Try removing the "" from the value_template, like this:

    value_template: >-
      {{ ((states(humidity)|float(0) < (states(humidity_ref)|float(0) + humidity_offest|float(0))) and
        (states(temperature)|float(0) < (states(temperature_ref)|float(0) + temperature_offest|float(0)))) }}
