Simple Light Automation Not triggering?

Configuration
1

Hi, I’m trying to create a simple light transition to change scenes depending on the time of the day. Does anyone know what I’m doing wrong?

  • id: transition_light
    alias: “Light transition”
    trigger:
    • platform: time
      minutes: ‘/5’
      seconds: 00
      condition:
    • condition: state
      entity_id: group.lights
      state: ‘on’
      action:
    • service: scene.turn_on
      data_template:
      entity_id: >
      {% if (float(as_timestamp(now)) > 18) and (float(as_timestamp(now)) < 19)%} # 6pm ~ 7pm
      scene.sunset
      {% elif (float(as_timestamp(now)) > 19) and (float(as_timestamp(now)) < 20)%} # 7pm ~ 8pm
      scene.feet_up
      {% elif (float(as_timestamp(now)) > 20) and (float(as_timestamp(now)) < 21)%} # 8pm ~ 9pm
      scene.Laila
      {% elif (float(as_timestamp(now)) > 21) and (float(as_timestamp(now)) < 22)%} # 9pm ~ 10pm
      scene.Jump
      {% elif (float(as_timestamp(now)) > 22) and (float(as_timestamp(now)) < 23)%} # 10pm ~ 11pm
      scene.relax
      {% elif (float(as_timestamp(now)) > 23) and (float(as_timestamp(now)) < 24)%} # 11pm ~ 12am
      scene.bedtime
      {% else %}
      scene.night_light
      {% endif %}

The error I’m seeing in the logs are:

Hi @bobokun, if you paste the above in Dev Tools/Templates you will see that it returns ‘None’.
as_timestamp(now()) returns the current timestamp (1503249967.039868) but this is not what you want for your template.
If you want to compare the current hour you can use something like:

now().strftime("%H") | int < 19

Hi @VDRainer! Thank you so much that fixed the issue :slight_smile: Sorry I’m quite new with Home Assistant. How do you test a piece of code from the template? When I copied the code it just shows up as a string in the output

Just put it in double curly brackets like:

{{ now().strftime("%H") }}

or you can paste your whole template (from first ‘{%’ to last ‘%}’) to see what you get.
