Can't seem to find a good example on the structure of this.

https://www.home-assistant.io/docs/scripts/#variables

#

Standard YAML syntax for dicts, lists, and key/value pairs

#

Curious why it is giving me curly brackets then

humble fable Apr 17, 2025, 5:32 AM

#

It's an empty dict

#

Represented in JSON syntax

#

Remove that and follow the examples in the docs to populate it with whatever you want

#

Ah, so it doesn't crash I suppose

#

However, am getting an error when creating the automation like this following the example. Am I missing something?

#

#

You're missing the {{ }} in your variable definition

#

And you need to quote it

#

See how you used the template properly below

#

Oh right. And also quotes, like so?

variables:

Yes

next oasis Apr 17, 2025, 5:39 AM

#

Message malformed: invalid template (TemplateSyntaxError: unexpected ')') for dictionary value @ data['actions'][0]['choose'][1]['sequence'][1]['sequence'][0]['variables']['new_volume']

Bonus paranthesis

You gave an extra )

#

Gosh darn it's late. Thanks for the help by the way!

#

I'm finishing it up right now, trying to add multiple variables

#

variables: 
  curr_volume: " {{ state_attr('media_player.chromecastultra1943', 'volume_level') }}"
  increment: 0.05

action: media_player.volume_set
metadata: {}
data:
  volume_level: "{{ curr_volume }} + {{ increment }}"
target:
  device_id: 62676f98a5d747221ed9faf9fb48d8f7
