How to render the following template?

[gitmirko]

Hi,
I'm struggling for hours to find the right approach to render the following template to be rendered by Home Assistant at the end.

Right now I was able to use the template node to render the following template:

state_attr("{{{flow.entity_id}}}", "volume_level")*{{{flow.volume_factor}}}|float

Is there any way to render this kind of template while preserving the double curly braces at the beginning and the end? If so I should be able to pass the output to node-red-contrib-home-assistant-websocket (api-render-template) directly and finaly achive my goal

{{ state_attr("{{{flow.entity_id}}}", "volume_level")*{{{flow.volume_factor}}}|float }}

Best regards
Mirko

Hi @gitmirko , welcome to the forum.

I assume you are using the core Template node for this?

If you check the sidebar help for that node, it explains what to do if you need {{/}} to appear in the generated content:

If you need to use {{ }} within your content, you can change the characters used to mark the templated sections. For example, to use [[ ]] instead, add the following line to the top of the template:
{{=[[ ]]=}}

Example

{{=<%  %>=}} {{ <%={{ }}=%>state_attr("{{{flow.entity_id}}}", "volume_level")*{{{flow.volume_factor}}}|float }}

Thank you. This worked like a charm:

{{=[[ ]]=}}
{{ state_attr("[[flow.entity_id]]", "volume_level")*[[flow.volume_factor]]|float }}

I still have not found the part in the help where it states this information.

Thank you as well. I got it to work with the first approach right away.

Think it depends on node-red version but there is a link in the help to this page. mustache(5) - Logic-less templates.

I see in your use of change delimiter, you no longer require that html entities are not escaped i.e the {{{ has become [[.
