When Is The Bus Coming - SBB Integration Automation

@miaucl I have installed the SBB Integration that is linked to the transportation schedule in Switzerland. I have set up a service and it tells me in how many minutes the next bus I am interested in is coming. And it also gives the next 2 scheduled busses, too. I wanted to create an automation that made the light turn color when the bus is coming in 5 minutes. I chose the departure entity and assigned a numeric state of below 5 (I assume this is in minutes) to trigger the automation. Because the time stamps are text I created a template in config.YAML to make a new entity called bus time remaining then used it in the automation.

template:
  - sensor:
      - name: "Bus Time Remaining"
        unit_of_measurement: "minutes"
        state: >
          {% if states('sensor.xxx_to_yyy_departure') != 'unavailable' %}
            {{ (as_timestamp(states('sensor.xxx_to_yyy_departure')) - as_timestamp(now())) // 60 }}
          {% else %}
            0
          {% endif %}

Here is the yaml for the automation.

alias: Light To Yellow For Bus
description: ""
triggers:
  - entity_id:
      - sensor.bus_time_remaining
    below: 5
    trigger: numeric_state
conditions: []
actions:
  - data:
      scene_id: before_blink
      snapshot_entities:
        - light.jimmy_s_office_light_2
    action: scene.create
  - data:
      rgb_color:
        - 254
        - 199
        - 0
    target:
      entity_id:
        - light.jimmy_s_office_light_2
    action: light.turn_on
  - delay:
      seconds: 10
  - data:
      entity_id: scene.before_blink
    action: scene.turn_on
mode: single

It also creates scene to go back to the original state of the light. I also wanted to make the light blink, but as it is an aqara ceiling light I am not sure that blinking is possible with a flash command. Anyway, the automation runs, but there is no light change. The traces come back clean but I get the feeling that it doesn’t recognize the 5 minutes. I am not an expert at yaml so it could all be wrong. I am fairly sure this should be possible. Perhaps there is another way. Any help or insight is appreciated.
