Help with service template and shell command

Configuration
1

I was trying to be efficient and avoid to create two automations.
Basically I want to trigger two different shell commands depending on trigger time.

I can´t get it to work however:

automation:
  - alias: "Send Message to Kitchen"
    trigger:
    - platform: time
      after: '08:00'
    - platform: time
      after: '20:00'
    action:
    - service_template: shell_command.{% if (trigger.now, '08:00') %}
      play_morning_greeting_in_kitchen
    {% else %}
      play_evening_greeting_in_kitchen
    {% endif %}

Anyone got a clue how to set this up?

I am not expierenced with datetime to give you a complete solution but it would be something like this.

service_template: >
  {% if trigger.now [IS CLOSE TO 8.00] %}
   shell_command.play_morning_greeting_in_kitchen
  {% else %}
    shell_command.play_evening_greeting_in_kitchen
  {% endif %}

Please take a look here https://home-assistant.io/topics/templating/ and don’t forget you can try out templates in the dev-console on your HA website.

PS: If this stays open long enough I might give it a try to solve it completly.

Thank you, I´ll experiment with this.

At first try I got an type error
unorderable types: datetime.datetime() < float()

Seems like trigger.now is datetime

EDIT: {% if trigger.now|float < 9.00 %} seems to work
EDIT2: spoke too soon. It seems that it always trigger the morning script

@PhyberApex: How can I see trigger.now in dev-console?

This is apparently true when time is 20:00:

trigger.now|float < 9.00

Just using now() should give you a current date time object.

If I float now() in the template tester, I get 0.0.

So this should do the trick for you…

service_template: >
  {% if trigger.now.time().hour == 8 %}
   shell_command.play_morning_greeting_in_kitchen
  {% else %}
    shell_command.play_evening_greeting_in_kitchen
  {% endif %}

As you can see this makes the assumption that it will trigger within the hour which should be fine in your case.
If you wonder how I found out how to do this:
I went into the template tester in the dev console and produced a datetime object to test around with according to the templating guide “now()” produces a datetime for now. From there I tried a few template functions until realizing that datetime is a python object which has attributes so I decided to look it up and found the way to access the hour with “datetimeobject.time.hour”. I provided my way of finding the solution in case you need something similar in the future to provide you with a way of thinking :slight_smile:

Thank you for digging into this, I´ll try your code
So trigger.now.time.hour is 24h clock then? Else 8 AM/PM would both show 8?

Do you mind sharing your code for testing in dev-console? Can be useful for me and others.

Hey,

yes it is 24h as can be seen here (forgot to link): https://docs.python.org/2/library/datetime.html#datetime.datetime.hour

My code I had in the dev console was:

{% set d= now() %}
{{ d }}
{{ as_timestamp(d) }}
{{ d.time().hour }}

PS: I edited the solution as I forgot the parenthesis after time

~Cheers
